An Evaluation of OpenAlex Level 0 - Art

OpenAlex is an online repository using an automated classification system. While existing studies highlight the overall usability of OpenAlex, this study analyzes the limitations and effectiveness of the Level 0 concept “Art.” Our findings suggest that the system has significant hierarchical and semantic shortcomings identified through a mixed-method research approach. This approach utilized qualitative and quantitative research methods to provide a holistic evaluation of the system, gauging its effectiveness in indexing papers. Moreover, we provide key insights into how improvements can be made to render OpenAlex an effective andusable classification system.
