Evaluating automatic medical concepts associations with human judgments

This paper evaluates the associations of a subset of concepts extracted by VCGS (Vocabulary Cluster Generating System), a concept extraction and association tool, based on 6000 titles and abstracts downloaded from EBSCOhost Health Source – Consumer Edition database, against associations decided by 30 participants. The results show that after incorporating LSA (Latent Semantic Analysis) technique, the VCGS system establishes term associations that are not significantly different from users.
