Bartell, Brian T.; And Others – Journal of the American Society for Information Science, 1995
Discussion of the failure of individual keywords to identify conceptual content of documents in retrieval systems highlights Metric Similarity Modeling, a method for creating vector space representation of documents based on modeling target interdocument similarity values. Semantic relatedness, latent semantic indexing, an indexing and retrieval…

Masys, Daniel R. – Academic Medicine, 1990
It is increasingly important to design local biomedical databases with attention to naming and classification standards. In some cases, common nomenclature will not be suitable, having been designed for another purpose, but much will be useful. Development of standard nomenclature is a social responsibility in the electronic biomedical community.…
