Explainable artificial intelligence in finance: a bibliometric and topic modeling analysis using BERTopic
摘要
This study investigates the evolving intersection of explainable artificial intelligence (XAI) and the financial sector. It explores how machine learning models’ transparency and interpretability shape decision-making processes in areas such as credit scoring, risk assessment, and market prediction. While conventional AI methods often function as opaque black boxes, XAI offers a solution to promote model accountability, fairness, and trust, which are critical factors in highly regulated and risk-sensitive financial environments. Drawing on 90 peer-reviewed articles retrieved from Scopus and Web of Science, this research applies both co-word analysis and BERTopic modeling to uncover major research themes and semantic structures within the relevant literature. The co-word network reveals distinct thematic clusters related to explainable credit risk models, interpretability in financial forecasting, and the integration of environmental, social, and governance (ESG) factors into AI-driven financial analysis. Meanwhile, topic modeling uncovers additional topics, including SHapley Additive exPlanations (SHAP) and Local Interpretable Model-agnostic Explanations (LIME)-based explainability techniques, human-AI collaboration in decision-making, and explainable deep learning for asset pricing and sovereign risk analysis. A temporal analysis of publication trends indicates increasing scholarly attention to transparency in AI in the wake of regulatory pressure and ethical considerations in finance. The findings point to a growing emphasis on embedding interpretability into AI models to support fairness, regulatory compliance, and better-informed financial judgments. This study contributes to both academic discourse and practical application by offering a detailed map of current XAI research in finance and identifying key directions for future inquiry and technological development.
