Purpose: The study aims to map and evaluate the intellectual, conceptual, and thematic evolution of research on Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL) in financial fraud detection. It seeks to uncover dominant knowledge structures, methodological shifts, and emerging frontiers that define the progression of this rapidly expanding domain.
Methods: A systematic bibliometric and thematic analysis was conducted on a corpus of 316 Scopus-indexed publications from 2020–2025. Using the SPAR-4-SLR protocol and the Biblioshiny (R-Bibliometrix) package, the study employed co-word analysis, thematic mapping, and conceptual structure modelling through Louvain clustering and fractional counting to identify key research patterns and trends.
Results: The analysis revealed four primary thematic clusters supervised deep learning models, unsupervised anomaly detection, AI-integrated real-time monitoring, and explainable fraud analytics. The field has evolved from rule-based and static models toward scalable, interpretable, and context-aware architectures such as graph neural networks and federated learning. Emerging studies emphasise explainability, compliance, and ethical deployment.
Implications: The findings guide researchers, practitioners, and regulators toward designing transparent, adaptive, and policy-aligned AI systems for financial fraud prevention and risk management.
Originality: This paper provides the first comprehensive, SPAR-4-SLR–driven bibliometric synthesis of AI and DL applications in financial fraud detection, integrating performance analysis with thematic and conceptual evolution to highlight future research pathways.
