The field of natural language processing is rapidly evolving, with a growing focus on fairness and bias evaluation in large language models (LLMs). Recent studies have highlighted the importance of addressing biases in LLMs, particularly in sensitive areas such as healthcare, finance, and law. Researchers are developing innovative methods to identify and mitigate biases, including metamorphic testing, causal reasoning analysis, and debiasing techniques.
One key direction in this field is the development of multimodal approaches to analyze and detect biases in LLMs. This includes the use of multimodal datasets, such as videos and images, to evaluate the performance of LLMs in detecting sexist and biased content. Additionally, researchers are exploring the use of causal inference and information theory to develop autonomous debiasing methods for LLMs.
The evaluation of social bias in LLMs is also an active area of research, with studies focusing on the analysis of bias in low-resource languages and dialects. This includes the development of new datasets and evaluation metrics to assess the performance of LLMs in detecting biases against marginalized groups.
Notable papers in this area include: Metamorphic Testing for Fairness Evaluation in Large Language Models, which introduces a metamorphic testing approach to systematically identify fairness bugs in LLMs. BiasCause: Evaluate Socially Biased Causal Reasoning of Large Language Models, which evaluates the causal reasoning process of LLMs when answering questions that elicit social biases. UoB-NLP at SemEval-2025 Task 11: Leveraging Adapters for Multilingual and Cross-Lingual Emotion Detection, which demonstrates the effectiveness of adapter-based fine-tuning for multilingual emotion detection. Information Gain-Guided Causal Intervention for Autonomous Debiasing Large Language Models, which proposes an information gain-guided causal intervention debiasing framework to autonomously debias LLMs.
