A data-driven assessment of biomedical terminology evolution using information theoretical and network analysis approaches

Résumé

The Medical Subject Headings (MeSH), one of the main knowledge organization systems in the biomedical domain, is constantly evolving following the latest scientific discoveries in health and life sciences. Previous research focused on quantifying information in MeSH using its hierarchical structure. In this work, we propose a data-driven approach based on information theory and network analyses to quantify the knowledge evolution in MeSH and the relevance of its individual concepts. Our approach leverages article annotations and their citation networks to compute the level of informativeness, usefulness, disruptiveness, and influence of MeSH concepts over time. The citation network includes the instances of MeSH concepts or MeSH headings, and the concept relevance is calculated individually. Then, this computation is propagated to the hierarchy to establish the relevance of a concept. We quantitatively evaluated our approach using changes in the MeSH terminology and showed that it effectively captures the evolution of the terminology. Moreover, we validated the ability of our framework to characterize retracted articles and show that concepts used to annotate retracted articles differ substantially from those used to annotate non-retracted. The proposed framework provides an effective method to rank concept relevance and can be useful in maintaining evolving knowledge organization systems.
