Abstract

Artificial Intelligence (AI) has emerged as a transformative force in the design, enhancement, and deployment of metadata systems within academic libraries. The current review synthesizes insights from recent studies focusing on AI-driven metadata enrichment, interoperability frameworks, cataloguing automation, user experience transformation, and the strategic repositioning of libraries in the digital era. Key contributions across the literature indicate that AI technologies—particularly machine learning, natural language processing, deep learning, and generative AI—are redefining metadata workflows, enabling faster resource discovery, improving interoperability, and supporting large-scale metadata harvesting through protocols such as OAI-PMH. Research further reveals that academic libraries are shifting from passive service units to proactive knowledge facilitation centres as AI augments both operational efficiency and decision-making processes. At the same time, challenges persist in areas such as ethics, metadata bias, algorithmic transparency, sustainability of AI models, and the need for digital competencies among library professionals. This review consolidates evidence from global library environments—including Asia, Europe, Africa, and the United Kingdom—highlighting converging trends and diverging implementations. It also proposes a future-oriented model for AI-enabled metadata ecosystems by integrating the findings of recent scholarly works. This review contributes to understanding how libraries can strategically adopt AI to enhance metadata quality, integrate digital collections, support research, and ensure long-term interoperability.

Conclusion

The review demonstrates that AI is fundamentally transforming metadata creation, enrichment, interoperability, cataloguing, and user experience in academic libraries worldwide. Through machine learning, natural language processing, deep learning, and generative AI, libraries are enhancing metadata quality, accelerating workflows, improving interoperability, and supporting more intuitive discovery experiences. The studies reviewed show a clear global trend toward smarter metadata ecosystems where AI augments human expertise and enables libraries to operate as proactive knowledge facilitators.

Despite these advancements, challenges persist, including algorithmic bias, ethical concerns, uneven adoption across regions, and the need for librarian upskilling. Addressing these challenges requires strategic planning, continuous evaluation, and hybrid human–AI models that maintain accountability and transparency. Future research should focus on developing sustainable AI frameworks, ethical metadata governance models, and scalable interoperability solutions that support global scholarly communication.
