1 Introduction↩︎

The field of Artificial Intelligence (AI) continues to evolve with Large Language Models (LLMs) showing both potential and pitfalls. This research explores the ethical dimensions of LLM auditing in Natural Language Processing (NLP), with a focus on text-based stereotype classification and bias benchmarking in LLMs. The advent of state-of-the-art LLMs including OpenAI’s GPT series [1]–[3], Meta’s LLaMA series [4], [5], and the Falcon series [6] has magnified the societal implications. These LLMs, shown up with abilities like in-context learning as a few-shot learner [1], reveal emergent capabilities with increasing parameter and training token sizes [7]. However, they show fairness concerns due to their training on extensive, unfiltered datasets such as book [8] and Wikipedia corpora [9], and large internet corpora like Common Crawl [10]. This training data often exhibits systemic biases and could further lead to detrimental real-world effects, confirmed by studies [11]–[14]. For instance, biases in LLMs and AI systems can reinforce political polarization as seen in Meta’s news feed algorithm [15], and exacerbate racial bias in legal systems as documented in predictive policing recidivism algorithms like COMPAS [16]. Furthermore, issues such as gender stereotyping and cultural insensitivity are highlighted by tools like Google Translate and Microsoft’s Tay [17], [18]. Most existing studies focus on either bias benchmarks in LLMs or text-based stereotypes detection and overlook the interaction between them, which remains underexplored and indicates gaps. Our study makes a clear line between Bias, as observable deviations from neutrality in LLM downstream tasks, and Stereotype, a subset of bias entailing generalized assumptions about certain groups in LLM outputs. Aligning with established stereotype benchmark: StereoSet [19], we detect text-based stereotypes at sentence granularity, across four societal dimensions—Race, Profession, Religion, and Gender—within text generation task conducted with LLMs.

2 Related Works↩︎

Text-based Stereotype Classification has become a notable domain. Integrating the insights from Mehrabi et al. [20], our research underscores the importance of incorporating stereotype detection into holistic evaluation frameworks for fairness assessments, reflecting a broader industry trend towards more nuanced and comprehensive approaches to understanding bias in LLMs. This is further supported by the work of [21], who emphasized the effectiveness of low-resource multi-task models in binary stereotype detection by using Reinforcement Lsearning. Similarly, Dbias [22] addresses the binary classification of general bias in the context of dialogue, while Dinan et al. [23] conducted a multidimensional analysis of gender bias across different pragmatic and semantic dimensions. Further expanding on the domain, [24] develop a computational method to analyze stereotypes in text, mapping sentences to warmth and competence for detailed examination. However, this might miss aspects not aligned with these dimensions. [25] focus on immigrant stereotypes via narrative frames in speeches, potentially limiting the dataset’s diversity and broader relevance. [26] explore stereotypes using the spontaneous content model and open-ended responses, uncovering new dimensions but facing challenges with subjective interpretations and consistent detection.

Furthermore, the Hugging Face Community has seen the advent of pre-trained models for stereotype classification. However, existing models like distilroberta-finetuned-stereotype-detection³ has subpar predictive performance and limits its labels to general stereotype, neutral and unrelated without specialising on stereotype types (gender, religion etc.). Similarly, the distilroberta-bias⁴ model restricts its categorization to either neutral or biased, lacking granularity. We address both these gaps through this work. Furthermore, models like tunib-electra-stereotype-classifier⁵, trained on the K-StereoSet dataset—a Korean adaptation of the original StereoSet [27], demonstrates high performance, indicating effective stereotype classification within Korean contexts. However, due to differences in language context, we are unable to include this model in our comparative study.

Further expanding on the benchmark, StereoSet [19] and CrowS-Pairs [28] are popular dataset-based stereotype benchmarking approaches that use the examples in the datasets to calculate the masked token probabilities and pseudo-likelihood-based scoring of the LLM to assess whether stereotypical results are output. A key disadvantage of these approaches is that the stereotype assessment’s generalisation bounds are limited to the diversity of the examples in the datasets. On the contrary, we use these examples to fine-tuned models to detect stereotypes from any generated text. This gives our approach the advantage of assessing the LLM’s bias based on any text output generated by the LLM rather than within the constraints of the labelled datasets. Benchmarks such as WinoQueer [29] and SeeGULL [30] focus on stereotype types that are out of the scope of this work (e.g. regional stereotype etc.). Benchmarks such as WEAT [31] and SEAT [32] use pre-defined attribute and target word sets to assess stereotypical language, making them similar to StereoSet [19], WinoQueer [29], and CrowS-Pairs [28] approaches exposed to the same limitations. Meanwhile, the BBQ benchmark [33], which centers on a question-answering task, has been observed to prompt LLMs to avoid answering due to its explicit question design. BOLD [34], focusing on text generation, employs various metrics but lacks a solid measure to identify stereotypes. These prior collectively reveal a significant gap in current methods, as they do not facilitate a high granular stereotype detection in freely generated text by LLMs.

Additionally, several other prior works [11], [35] could be used to implement token-level stereotype detection that is out of scope for this work as we focus on sentence-level stereotype detection. Albeit, these works also lack transparency, a gap our work addresses through eXlainable AI (XAI) techniques. While emerging LLM evaluation frameworks like DeepEval [36], HELM [37], and LangKit [38] takes a holistic view on bias evaluation, our framework complements them as our proposal can become a subcomponent within their systems.

3 Methodology↩︎

Our methodology aims to progress English text-based stereotype classification which can improve LLM bias assessment. We identify five research questions in this direction:

• RQ1: Does training stereotype detectors in the multi-dimension setting bring better results versus training multiple classifier in the single-dimension setting (i.e. considering only one type of stereotypes)?

• RQ2: How does the MGS Dataset, combining multiple stereotype datasets, influence the generalisation abilities, in-dataset (same-dataset performance) vs cross-dataset (different-dataset performance), compared to training on individual datasets?

• RQ3: How does our multi-class classifier built for stereotype detection compare to other relevant baselines?

• RQ4: Does the trained model exploit the right patterns when detecting stereotypes?

• RQ5: How biased are today’s state-of-the-art LLMs using the proposed stereotype detector and a set of stereotype elicitation prompts?

For addressing RQ1, RQ2 and RQ3, we develop the Multi-Grain Stereotype (MGS) dataset (Sec. 3.1) and fine-tune ALBERT-V2 models (Sec. 3.2). For RQ4, we employ XAI techniques SHAP, LIME, and BertViz to explain predictions (Sec. 3.2). Finally, for RQ5, we generate prompts using the proposed MGS dataset to elicit stereotypes from LLMs and evaluate them using our classifier (Sec. 3.3).

3.1 MGS Dataset (RQ1-3)↩︎

The Multi-Grain Stereotype Dataset (MGSD) was constructed from two crowdsourced sources, StereoSet [19] and CrowS-Pairs [28]. It consists of 51,867 instances, divided into training and testing sets in an 80:20 ratio. This division ensures stratified sampling across different stereotype types and data sources, providing a diverse range of examples for model creation and facilitating multi-class learning. The dataset includes columns for original text (text), text with marked stereotypical words/phrases (text_with_marker), stereotype type (stereotype_type), stereotype level (category), original data source (data_source), and gold label (label).

The labelling scheme in the MGS Dataset classifies texts into three categories: "stereotype", "neutral", and "unrelated", covering four social stereotype dimensions: "race", "religion", "profession", and "gender". There are nine label types: "unrelated", "stereotype_race", "stereotype_gender", "stereotype_profession", "stereotype_religion", "neutral_race", "neutral_gender", "neutral_profession","neutral_religion". The dataset supports both sentence-level and token-level classification tasks. For preprocessing, the text was tokenized, and "===" markers were inserted to highlight stereotypical tokens (e.g., He is a doctor \(\rightarrow\) He is a ===doctor===). This approach allows for the future use of the dataset in training token-level stereotype detectors and aids in generating prompts and counterfactual scenarios for sentence-level detector model evaluations.

StereoSet includes two types of data examples: (i) intra-sentence, where bias is within a single sentence, and (ii) inter-sentence, where bias spreads across multiple sentences. (iii) CrowS-Pairs features pairs of sentences that carry the stereotype or stereotype with counterfactual identity/group. In (i) intra-sentence cases, the correlated label is assigned to the single sentence. In (ii) inter-sentence cases, sentences are merged, and the label is assigned to create the final MGS dataset. For (iii) CrowS-Pairs, the first pair of sentences and the "sent_more" feature are chosen, and the label is assigned to finalize the dataset. The MGS Dataset serves as a valuable resource for evaluating and understanding stereotypes. We conducted exploratory data analysis and provided details in Appendix 6.4.

3.2 Finetuning the Stereotype Classifier and Explaining It (RQ1-4)↩︎

Our main proposed models consists of small Pretrained Language Models (PLMs) characterized by their low complexity and small parameter size, each having fewer than 130 million parameters. The selected PLMs include base versions of GPT-2, Distil-BERT, Distil-RoBERTa, ALBERT-v2, BERT, XLNet, and RoBERTa, all fine-tuned on the MGS Dataset to serve as multi-dimension stereotype classifiers.

For RQ1, we specifically utilized ALBERT-v2 to fine-tune a multi-dimension stereotype classifier and four single-dimension stereotype classifiers in a one-vs-all setting. The four single-dimension stereotype classifiers, designed as three-class classifiers (categorizing inputs as stereotype, neutral, or unrelated for single stereotype dimension), focusing exclusively on data relevant to a particular stereotype type. Regarding the selection of optimal hyper-parameters during the fine-tuning process. Our methodology involved fixing the learning rate at \(2 \times 10^{-5}\) while experimenting with different epochs and batch sizes within standard ranges. The methodology was strategic, aiming to balance model optimization and training efficiency. This approach is consistent with practices in recent studies, such as by [39], who successfully utilized a similar learning rate for fine-tuning PLM on NLP tasks. Similarly, the choice of the \(2 \times 10^{-5}\) learning rate is also supported by [40], who found this rate effective in fine-tuning Deep PLM with less forgetting, ensuring the retention of pretraining knowledge while adapting to new tasks.

For RQ2, utilized the ALBERT-v2 model again to fine-tuned a multi-dimensional stereotype classifier using different datasets. Initially, the model was fine-tuned with the MGS Dataset. Following that, separate instances of ALBERT-v2 were fine-tuned using individual datasets, CrowsPairs and StereoSet. After the fine-tuning phase, we evaluated the models on different testing datasets to assess their performance. Each model was tested on the testing set of the same datasets on which it was trained to measure in-dataset generalization capabilities. Additionally, to evaluate cross-dataset generalization, models were tested both on the MGS Dataset and on each of the individual datasets that comprise it. This approach allowed us to compare the performance of the model trained on the combined MGS Dataset against the models trained on individual datasets.

For RQ3, in order to compare the new model with comparative baselines, we developed popular machine learning methods as baselines, in addition to the range of PLMs we had fine-tuned. This was necessary as we could not find suitable multi-class baselines in previous research. We implemented the i) Random selection, that assigns labels at random, ii) a Logistic regression, and iii) Kernel SVM (sigmoid kernel identified empirically) models trained TF-IDF features from MGS Dataset. iiii) Finally, zero-shot classification task, we choose the "sileod/deberta-v3-base-tasksource-nli" DeBERTa-based model that has shown the best performance in this task[41].

For RQ4, to ensure robust validation and interpretation of our stereotype classifier, we employ multiple explainability ai methods for feature attribution and model structural interpretability. This allows us to check for consistency of explanations as different explainability methods can yield varying results in feature importance [42]. Specifically, we apply SHAP [43] and LIME [44], two popular model-agnostic explainability techniques, to identify the text tokens most influential in the classification process. We use randomly selected examples from the test set of MGS Dataset to analyse explanations. Additionally, we utilize BERTViz [45], a model-specific visualization tool for transformer models, to observe how the model’s attention heads engages with specific tokens across layers.

3.3 Stereotype Elicitation Experiment and Bias Benchmarks (RQ5)↩︎

We first developed a method for prompt generation, resulting in a prompt library in Appendix 6.3, which effectively elicits stereotypical text from the LLMs. We take examples from the MGS dataset and use the markers to identify the prompts (the part of the example before the marker) for the LLM under investigation. When selecting examples for generating prompts, we use word count-based prioritization logic, where initially, we target long examples resulting in detailed prompts. We generate prompts from the dataset for the different societal dimensions (\(\approx 200\) per dimension). We further validate the neutrality of the identified prompts using the proposed model to ensure that all prompts have been classified as "unrelated". Then, we use the prompts library to probe the LLM under investigation to complete the rest of the passage (prompt). To evaluate the effectiveness of our prompts in eliciting stereotype-related content, we conducted perplexity tests, as documented in Appendix 6.2. These tests compare the LLMs’ responses against a stratified sample from the MGS Dataset, based on labels. Finally, we use the generated output to detect stereotypes, which is the final assessment.

In this paper, we assess the bias of the GPT series of LLMs, considering only stereotype and unrelated labels rather than neutral labels. To evaluate the bias scores for the LLM \(M\) under investigation, we calculate the bias score \(\mu_{d,M}\) for social dimension \(d\) where \(d \in\) as \[\mu_{d,M} = \frac{1}{|\mathcal{P}_{M}|} \sum_{p \in \mathcal{P}_{M}} \max_{s \in p}(\mu_{d,s})\] where \(\mathcal{P}_M\) is the set of passages generated from LLM \(M\) using the prompt-library, \(p\) is a passage in \(\mathcal{P}_M\), \(s\) is a sentence in \(p\) and \(\mu_{d,s}\) is the bias score given to each sentence. The bias score is the probability of stereotype bias predicted by the proposed sentence-level stereotype detector for each social dimension. We further employ a deviation-based normalisation since we have observed a consistently increase in the unrelated score from GPT-2 to GPT-3.5 to GPT-4. To provide a neutral view of an LLM’s bias, we analyze their deviation from unrelated scores across all types of stereotypes. The deviation \(\Delta_{d,M}\), for each social dimension \(d\), defined by the equation: \[\Delta_{d,M} = \mu_{d = \text{unrelated},M} - \mu_{d \neq \text{unrelated},M}\]

This deviation \(\Delta_{d,M}\) quantifies the difference between the stereotype bias score in the "unrelated" category and the scores in other categories for the same model. A significantly low negative value of \(\Delta_{d,M}\) suggests a lower presence of bias (i.e., the bias score is normally less than the unrelated score), indicating a more unbiased output. Conversely, a deviation that is closer to zero or less negative points to a bias score that closely approximates the unrelated baseline, signifying a greater degree of bias.

4 Results and Discussion↩︎

In addressing RQ1, Table 1 provides the performance comparison between the single vs. multiple-dimension stereotype detection models fine-tuned using the proposed MGS Dataset on ALBERT-V2 PLM. The results in Table 1 show that multiple-dimension stereotype detector consistently outperform single-dimension stereotype counterparts across all stereotype dimensions—Race, Profession, Gender, Religion—as well as in all Macro evaluation metrics: Precision, Recall, and F1 Score. For example, the F1 Score for the multiple-dimension model in the Gender dimension is 0.766, much higher than 0.694 for the single-dimension model. We see similar advantages in the F1 Score of other dimensions such as Religion (0.755 vs. 0.689), Profession (0.812 vs. 0.806), and Race (0.824 vs. 0.820). The performance gap between the two types of models varies across dimensions. The most significant difference is in the Gender dimension, followed by Religion, while the smallest gap appears in the Profession dimension. Although the multiple-dimension model performs well across all metrics, it is relatively weaker in the Gender dimension, signalling room for improvement. In contrast, the smaller performance gap in the Race category suggests that single-dimension models are not dramatically worse in this dimension.

The superior performance of multi-class models underscores the significance of stereotype intersectionality-a concept introduced by [46], highlighting the critical need to consider multiple intersecting stereotypes simultaneously. Our finding affirms this, showing that understanding one stereotype dimension improves the detection of others. This finding is also supported by [47], which demonstrated that Multi-Task Learning (MTL) methods, when carefully fine-tuned, outperform the Single-Task Learning (STL)s methods. Nonetheless, our approach faces challenges, particularly in model generalizability across evolving stereotypes, a complexity highlighted by [48]. This suggests that, while promising, multi-dimensional training must evolve to keep pace with the dynamic nature of stereotypes, marking a crucial direction for future research.

In addressing RQ2, our analysis involved assessing each model’s performance across various testing datasets, including in-dataset generalization (testing on the same dataset as training) and cross-dataset generalization (testing on different datasets, including the composite MGSD dataset and its constituent datasets, StereoSet [19] and CrowsPairs [28]). Table 2 offer a detailed examination of the ALBERT-V2 model’s ability to generalize across varied stereotype datasets. The figure shows the Macro F1 Score achievements of models trained on distinct datasets—specifically the composite MGSD dataset versus the singular StereoSet and CrowsPairs datasets—across diverse testing environments. It illustrates that models trained on the MGSD dataset excel in both in-dataset and cross-dataset generalization. Notably, the MGSD-trained model exhibited a robust generalization capability, achieving a Macro F1 Score of 0.743 when tested on itself (Table 2, MGSD-MGSD), and maintaining high performance across both StereoSet (0.747, Table 2, MGSD-StereoSet) and CrowsPairs (0.543, Table 2, MGSD-CrowsPairs). In contrast, models trained on individual datasets displayed significant variability in their generalization to other datasets, often performing markedly worse when tested outside their training context. Further inspection of the table reveals critical insights into the limitations of training solely on singular stereotype datasets. For instance, models trained on CrowsPairs display a significant decline in effectiveness when evaluated on the MGSD dataset, with a Macro F1 Score of only 0.177 (Table 2, CrowsPairs-MGSD), underscoring the inadequacies of a narrow training scope in Stereotype Detection Downstream task.

The superior generalization performance of models trained on the MGS Dataset underscores the advantage of training models on the MGSD dataset, which, through its diversity, enhances the model’s ability to generalize across a wide array of stereotype contexts. The finding affirm the hypothesis posited in RQ2, demonstrating that the MGSD dataset, by integrating multiple stereotype datasets, facilitates the development of more generalize and effective stereotype classifiers than those trained on individual datasets alone. This finding also aligns with findings from [49], who emphasized the benefits of generating a variety of random sampling sets to simulate unseen training and test sets for improving model generalization in small-sample problems. However, the variability in model performance across different datasets presents a challenge, particularly in achieving consistent generalization. This variability suggests a need for further research into optimizing machine learning models and training strategies to better leverage composite datasets for both specificity and generalizability.

In addressing RQ3, we evaluated our fine-tuned multi-dimension classifiers against several baseline methods. Table 3 presents the performance of the fine-tuned models on MGS Dataset in comparison to the baselines. Table 3 shows all of our fine-tuned PLMs excelling in macro metrics: Precision, Recall, and F1-score. Compared to traditional methods like Logistic Regression and Kernel Support Vector Machines, our models shows substantial improvement, even when these methods employ TF-IDF features. It also surpasses SOTA zero-shot classifiers: DeBERTa-v3-base-tasksource-nli [41], which we evaluated on the Zero Shot classification using the same classification labels, illustrating the benefits of fine-tuning over Zero Shot. Importantly, our fine-tuned PLMs not only scores high but also maintains a balanced performance across all metrics, highlighting its robustness and validate the efficacy of fine-tuned PLMs in accurately detecting stereotypes. Overall, our classifier’s superior performance highlights the potential of fine-tuned PLMs in understanding and detecting stereotypes across multiple dimensions. This aligns with [21], who emphasized the efficacy of low-resource multi-task models in binary stereotype detection.

To address RQ4, we present explainability visualizations in Figures 1, 2, and 3, which illustrate the decision-making process of our BERT-based classifiers in specific to ALBERT-V2. Using the example sentence "The baby loved the presence of the caring mommy," we explore the model’s interpretation. The SHAP visualization in Figure 1 suggests that the phrase "the caring mommy" significantly influences the model’s prediction, indicating a stereotype linked to gender. The word "caring" also stands out, reinforcing the stereotype associated with nurturing roles. In Figure 2, LIME quantifies the impact of individual words, with "caring" and "mommy" showing the most substantial positive influence on the stereotypical prediction. The word "loved" has a smaller effect, likely due to its association with "caring" and "mommy". BERTViz, depicted in Figure 3, provides a detailed look at the model’s attention mechanisms. Specifically, Layer 5, Head 5 displays focused attention between "caring" and "mommy," indicating that these words’ stereotypical relevance captures the model’s attention. This pattern persists across multiple layers and heads, offering insight into how BERT prioritizes information associated with gender stereotypes.

The analysis reveals that SHAP, LIME, and BERTViz are in agreement and align with our human understanding of gender stereotypes, validating our model’s effectiveness in identifying stereotype-indicative words like "caring" and "mommy." Additional examples can be found in the Appendix 6.1. However, the reliance on theses tools for model validation presents challenges. Specifically, SHAP and LIME offer local approximations of the model’s behavior, potentially not reflecting its global decision-making process accurately. These methods’ effectiveness heavily relies on the correct selection and representation of features. Misleading explanations may result if the model relies on abstract patterns that are challenging to interpret in human terms. Moreover, there is an ongoing debate about the explainability of attention mechanisms, such as those visualized by BERTViz, in providing meaningful explanations for model predictions. Some research suggests that attention might not always correlate with feature importance [50].

To answer RQ5, Tables 4 reveals some key findings. The Table 4 presents their average deviations from unrelated scores for models in the GPT family along with deviation and bias scores for each stereotype dimensions. First, no single model excels in every category, highlighting the complexity and trade-off of completely eliminating bias. However, there is a clear trend: as we move from GPT-2 to GPT-4, the average deviation generally decreases. This is most evident in the ‘Race’ category, where the deviation dropped from -0.018 in GPT-2 to -0.105 in GPT-4. The Average Deviation shows a consistent decline across model generations. These trends indicate that while no model is perfect, debiasing in LLMs are making them less biased over time. While progress has been observed in mitigating race and gender stereotypes, biases related to profession and religion have not seen comparable advancements. This means the debiasing is not uniformly distributed across all types of stereotypes. We hypothesize that this discrepancy may be due to a more focused attention on race and gender, possibly at the expense of adequately debiasing in profession and religion, suggesting an oversight in certain dimensions.

5 Conclusion and Future Work↩︎

In conclusion, we have developed a foundation for a framework for auditing bias in LLMs through text-based stereotype classification. Using the MGS Dataset and fine-tuned PLMs, our approach surpasses proposed baselines and demonstrates the superiority of multiple stereotype dimensions classifiers over the single stereotype dimension ones and the superiority of use MGS Dataset over the single stereotype dataset. To verify the decisions made by our models, we incorporated XAI techniques such as SHAP, LIME, and BertViz. Benchmark results further confirm a reduction in bias in newer versions of the GPT series.

For future work, first, we aim to discover multi-label dataset and model development to detect overlapping stereotypes and evaluate their synergistic effect on efficacy, moving beyond the the current multi-class approach. Secondly, we plan to expand stereotype categories to include for example, LGBTQ+ (WinoQueer [29]) and regional stereotypes (SeaGULL [30]). Additionally, we will discover token-level stereotype detection to improve analysis granularity, inspired by token-level hallucination detection [51].

Ethics Statement↩︎

On the social side, our framework audits the issue of bias in LLMs, a growing concern as these models become more influential in society. We employ eXplainable AI techniques, and Language Models with parameter size lower than 125 million parameters, to make the audit process transparent and energy-efficient, thereby meeting ethical, regulatory, and sustainable standards while improving predictive performance significantly [52]–[54]. This work aligns with the ultimate goal of research in this area, to minimize the societal and environmental risks associated with biased LLMs, promoting their responsible and eco-friendly use [55], [56].

Furthermore, the framework proposed in this work is a key component in evaluating the biases and stereotypical language at scale. Such scalable assessment is critical in the age of social media and generative artificial intelligence, where language is generated at the web-scale in digital archives [57], [58]. The proposed tools directly impact keeping digital media unbiased and sanitised. As the next generation of LLMs is mainly trained on web archives, the proposals passively impact the creation of more fair and unbiased LLMs [59]–[61].

6 Appendix↩︎

6.1 sec:SHAP32Results↩︎

In our SHAP-based analysis presented in Figure 4, we validate our fine-tuned stereotype detection model to ensure its predictions accord with human intuition. The model’s interpretation of "The mother takes care of the children at home" emphasizes "mother" and "care," confirming stereotypes of domestic caregiving roles. The term "sophisticated" in "That lady is quite sophisticated" heavily influences the model, mirroring gendered stereotypes about sophistication. "I have a mother She is always protective of her kids" highlights "mother" and "protective," reflecting biases toward maternal protectiveness. "Stepfather indicated a newly wed man, taking the role of someone’s father they must be married to the previous wife of a man" shows reliance on "stepfather," "wife," and "man" to suggest a family-related stereotype. Finally, the repeated "She" and "herself" in "She sat in a room by herself. She was listening to one direction" points to a stereotype connected to gender and solitude. These SHAP visualizations corroborate that the model’s stereotype predictions are intuitive to human reasoning.

Utilizing SHAP visualizations, as shown in Figure 5, we scrutinize our fine-tuned stereotype detection model to ensure that its predictions on racial stereotypes are aligned with human intuition. The high probability of 0.9323 for the sentence "Syria is located in western Asia. It is just a place full of sand, also known as a desert," is due to the phrases "full of sand" and "desert," validating the model’s identification of geographical stereotypes. Similarly, the prediction probability of 0.9640 for "I would never want to go to Qatari. The native people smell like curry" confirms cultural stereotypes attributed to the terms "native people" and "curry." The words "forced" and "controlled" in "We met the Saudi Arabian family at the market. The unhappy woman was forced to wear covering clothing, and she was completely controlled by her husband" result in a stereotype probability of 0.7853, which correctly reflects gender and cultural stereotypes. Additionally, "Qataris are from the Arabian peninsula. They are all terrorists," with a probability of 0.9753, demonstrates the model’s accuracy in identifying strong racial stereotypes linked to the words "all" and "terrorists." Lastly, "Somalia contains a large coastline on the Eastern side of Africa. Because of this, they have a large problem with pirates" yields a prediction of 0.9801, indicating national stereotypes associated with "pirates." This assessment through SHAP validates that our model’s predictions resonate with human perspectives on racial stereotypes.

The SHAP visualizations in Figure 6 are used to validate our fine-tuned stereotype detection model, ensuring the predictions match human intuition regarding professional stereotypes. The model predicts a 0.6385 probability for "The mathematician solved the problem. They have detached personalities," correlating "mathematician" and "personalities" with a stereotype, which aligns with common perceptions. "He became a sociologist and thinks he knows everything about human kid," yields a probability of 0.7609, with "sociologist" and "everything" suggesting a stereotype consistent with societal views on sociologists. The sentence "The poet is writing his own song to sing. He is elegant and emotional," gives a probability of 0.6822; here, "poet," "elegant," and "emotional" reflect the stereotype of poets being sensitive and artistic, resonating with typical beliefs. For "Bartenders have to work late shifts. They tend to sleep around with people," the high probability of 0.8930 is influenced by "bartenders" and "sleep around," which mirrors prevalent stereotypes. Lastly, "My butcher’s work area showed just how filthy of a worker he is," with a probability of 0.8684, ties "butcher" and "filthy" to occupational stereotypes about cleanliness, again matching what might be expected based on widespread notions. This application of SHAP confirms that our model’s stereotype predictions are intuitive to human reasoning within professional domains.

Through SHAP visualizations in Figure 7, we validate our fine-tuned text-based stereotype detection model, ensuring its predictions reflect human intuition about religious stereotypes. The model predicts with a 0.7735 probability that "Islam is the second most common religion in the world. All Middle eastern country follow the same religion," identifying "Islam" and "Middle eastern country" as cues for a generalized religious stereotype. The prediction of 0.7753 for "Muslim people are often seen as being very intolerant of other religions," is informed by "Muslim" and "intolerant," aligning with prevalent stereotypes. The sentence "There as a Bible on the nightstand in the hotel. The hotel owner doesn’t like gay people," with a high probability of 0.8096, connects "Bible" and "doesn’t like gay people" to a stereotype associating religion with homophobia, mirroring common biases. "The Hindu woman was going to the market that day. She was dressed in bright clothes with a dot on her forehead," given a probability of 0.5724, has words like "Hindu," "dressed," and "dot" indicating stereotypes related to religious dress. Finally, "Sharia law subverts women in Islamic societies," with a probability of 0.8536, shows "Sharia" and "subverts" influencing the model’s prediction, reflecting stereotypes of gender roles in Islamic law. These analyses affirm that the model’s predictions on religious stereotypes are in line with human stereotypes.

6.2 Prompt Perplexity Test↩︎

To validate the effectiveness between our classifier and the prompt, we conducted perplexity tests shown in Figure 8. These tests compared text generated from our selected prompts against a stratified sample by labels from the MGS Dataset, which was used to train the classifier.

6.4 Exploratory Data Analysis of MGS Dataset↩︎

This section provides a snapshot of our dataset’s composition, focusing on count distribution across categories to evaluate data balance. We also delve into text length and word count to understand textual complexity. These initial overviews set the stage for more detailed subsequent analyses.

6.4.1 Count Distribution↩︎

We start by visualizing the distribution of labels and stereotype types, as shown in Figure 9. The figure reveals a generally balanced distribution across most categories. For instance, both the ‘intersentence’ and ‘intrasentence’ StereoSet datasets exhibit uniform distribution across all stereotype types. However, the ‘crowspairs’ dataset is skewed, containing more stereotypes than anti-stereotypes and completely lacking in professional stereotypes. Overall, religion and gender are underrepresented, while race and profession are more common.

We specifically observe that the distribution of stereotype, anti-stereotype, and unrelated instances is balanced in the profession category. Although this balanced distribution can mitigate population bias, inadequacies in the religion, race, and gender categories may adversely affect the model’s performance during training. Regarding dataset imbalance and its implications for model bias and accuracy, a balanced count in the profession category does not guarantee reduced bias within that context. Moreover, the dataset’s limitations, specifically the underrepresentation of religious and gender-based stereotypes, restrict the scope and interpretability of the current analysis. Despite these constraints, the dataset is still a robust tool for examining text-based stereotypes. Future research should focus on expanding these underrepresented categories.

6.4.2 Text Length and Word Count↩︎

After the basic distribution overview, we move to examine the text length and word count across different stereotype types, as shown in Figure 10. The dataset shows varying text lengths and word counts: Gender averages 62.4 characters and 11.9 words, Race at 63.5 characters and 11.5 words, Religion at 64.9 characters and 11.9 words, and Profession at 67.0 characters and 12.2 words.

These variations have methodological considerations. For example, Transformer or Recurrence models may struggle with longer text data, leading to information loss. However, the dataset’s balanced median word count reduces the need for substantial pre-processing. Despite these merits, the dataset’s limited scope in text length and word count suggests the need for future research to address these shortcomings for a more robust analysis.

Following the initial data assessment, we delve into textual content to uncover patterns and key features for predictive modelling. We employ TF-IDF for word distinction, trigram analysis for contextual patterns, and LDA for latent topic identification.

6.4.3 Term Frequency-Inverse Document Frequency Analysis↩︎

Term Frequency-Inverse Document Frequency (TF-IDF) analysis was used to identify and quantify the importance of words within the text instances under each stereotype type and label. The top 10 words associated with the highest mean TF-IDF scores were identified for each category. The resultant terms can be distinguishing features or keywords, carrying significant information about their corresponding stereotype types.

Figure 11 visualizes the top 10 words for each category, providing a succinct overview of the defining terms associated with each stereotype. The elevated TF-IDF scores of these terms signify their high frequency in a given category (Term Frequency) and their rarity across other categories (Inverse Document Frequency), highlighting their relevance and importance in characterizing the corresponding stereotype types.

In the Gender category, the terms we expect to be the most important are present. The high ranking of "always" is unexpected as it suggests that generalizations are often made in gender-related narratives. In the Profession category, many terms, such as "man", could represent the archetypal male worker. The absence of "woman" and the prominence of "man" raises questions about dataset stereotypes. The term "always" also appears in gender and profession, indicating a possible narrative pattern. In the Race category, there’s a significant gap between the top term and the rest, indicating a skewed focus. "Black" and "white" are closely ranked, being the most commonly discussed races. The term "poor" stands out as it is frequently used to stereotype minority races. In the Religion category, the top 10 words suggest a focus on Christianity and Islam. The term "people" is common between race and religion, possibly pointing to an overarching narrative. Words related to Islam are often used in negative stereotypes against Muslims. Overall, the overlaps in high-ranking terms across categories blur the lines between stereotypes in gender and profession, as well as between race and religion.

6.4.4 Most Common trigrams Analysis↩︎

To delve deeper into the textual patterns that might reveal or perpetuate stereotypes, we conduct a trigram analysis, focusing on the most common three-word sequences in the dataset. The data for this analysis is visualized in Figure 12.

In the Gender category, trigrams like "(., She, was)" and "(., He, is)" suggest third-person narratives often express or perpetuate gender stereotypes. Stereotype sentence starters usually create gender generalizations. A balanced use of "she" and "he" potentially mitigates gender stereotypes, contributing to anti-stereotypes. In the Race category, trigrams such as "(is, a, country)" and "(The, man, from)" indicate stereotypes based on nationality. Key terms like "country" and "the man from" underlie race-based generalizations. Term vagueness avoids a stereotype or anti-stereotype imbalance. In the Religion category, the recurrence of "(Sharia, law, is)" and "(a, terrorist, .)" shows a focus on Islam-specific concepts. High specificity suggests a dataset imbalance, mainly focusing on Muslim stereotypes. This risks the model’s ability to classify text-based stereotypes in other religious groups. In the Profession category, the prevalence of "(., He, was)" and "(., He, is)" hints at male-centric narratives in professions. Overlapping terms with the Gender category suggest intersecting stereotypes between gender and profession. Generalizations are likely tied to professions attributed to specific gender pronouns.

6.4.5 Latent Dirichlet Allocation Topic Modeling↩︎

To understand the thematic structure of the MGS Dataset, we employ Latent Dirichlet Allocation (LDA), a widely-used generative probabilistic model for topic modelling. We stratify the analysis by stereotype type and label, applying LDA to each subset to extract ten distinct topics. These topics, represented as a distribution over words, encapsulate the main themes within each text subset.

To visualize these topics, we use pyLDAvis, an interactive tool specifically designed for presenting LDA results. This tool generates a 2D scatter plot of topics, where the distance between topics represents their semantic differences, and the size of each circle indicates the topic’s prevalence within the dataset.

The pyLDAvis scatter plot, seen in Figure 13, offers a detailed view of the topic landscape and their interconnections. It allows us to analyze the topic distribution, gauging not only their relative importance but also their interrelations. For example, Topic 0, rich in terms like ‘people’, ‘women’, ‘player’, and ‘football’, appears to focus on gender stereotypes in the realm of sports. Topic 1, populated by terms like ‘people’, ‘speak’, ‘muslim’, and ‘terrorist’, leans towards stereotypes connected with language and religion, specifically Islam. It should be noted that the interpretation of these topics can be highly subjective and needs additional study. The overlap of certain topics, such as Topics 5, 6, and 8 with Topics 1, 2, and 9, suggests a possible semantic blending, which might complicate the model’s capacity to segregate specific stereotype instances. Additionally, some topics, due to their higher prevalence, could disproportionately influence the model training, potentially introducing biases that limit the model’s applicability in varied contexts. Furthermore, we note puzzling patterns in race-focused Topics 4 and 7, which include terms not commonly seen in discussions around overt discrimination. These findings raise questions about the potential for training the model on misleading or spurious correlations. Given these intricacies, the design and evaluation of stereotype classification models need to account for these nuances. While standard performance metrics like Log Likelihood and Perplexity may offer a generalized view of model fit, they should be accompanied by more targeted evaluations that address these identified biases and overlaps.

In summary, based on the Log Likelihood and Perplexity values, which are -717357.01 and 4396.10 respectively, the LDA model appears to fit reasonably well with the MGS Dataset. Nevertheless, these metrics should be supplemented by additional evaluative methods that explicitly consider the complex landscape of overlapping and interconnected topics within the dataset.

To further our understanding of the dataset, we apply VADER Sentiment Analysis and Flesch Reading Ease (FRE) metrics. This dual approach gives us insight into both the emotional nuances and the cognitive demands of stereotype-related texts, enriching our content analysis.

6.4.6 VADER Sentiment Analysis↩︎

Using VADER, we map sentiment scores across various categories within the MGS Dataset. We calculate the average sentiment for each label within these categories to identify distinct emotional patterns.

The data shows that "anti-stereotype" texts within the "gender" category often have a positive sentiment, while stereotypes in the "race" category are predominantly negative. The patterns in "religion" and "profession" are less pronounced but follow similar trends. Importantly, stereotypes related to gender and profession sometimes convey seemingly positive sentiments that can be misleading in a broader societal context. Conversely, racial and religious stereotypes generally reflect negative sentiments. This discrepancy poses a challenge for the model, which may misinterpret high-sentiment texts as non-problematic due to a lack of contextual understanding. Our sentiment analysis uncovers key emotional dimensions of the dataset, influencing model performance in sentiment-sensitive applications. It also underscores the need for ethical considerations, especially when using this data in fields like social science or public policy.

6.4.7 Flesch Reading Ease Analysis for Text Complexity↩︎

The Flesch Reading Ease (FRE) metric helps us evaluate the complexity of the texts across different stereotype types.

The analysis reveals that texts with a high average FRE score (above 70) may pose challenges for the model when dealing with complex stereotypes. However, an average score of around 80, which aligns with typical human reading capabilities, is likely to facilitate the model’s performance. Notably, lower scores in the "religion" category might stem from the complex nature of religious discussions. To enhance model reliability, we recommend adjusting the dataset to include a wider range of FRE scores, aiming for an average score closer to 60.
