Freedom Versus Standard in Article Keyword Generation: An Empirical Study

This study compares the overlap among author-furnished keywords, Library of Congress Subject Headings and a consolidated controlled vocabulary for articles published in Annals of Library & Information Studies, published by NISCAIR from 2018 to 2023, India. The study focuses on the effectiveness of controlled vocabulary for keyword generation. The work is intended to contribute to the literature on author keywords versus keyword standardization in measuring information retrieval efficacy in real-time. The aggregated controlled vocabulary constructed for this study provided a positive result, showing the usefulness and requirements of such a robust controlled vocabulary. The study reflects the extended views of thesauri for a standard author keyword suggester or recommender system.
