Abstract

The patterns of overlap between terms which are closely related in a thesaurus are considered. The relationships considered are parent/child, in which one term is a broader term of the other, and sibling in which to 2 terms share the same broader term. The patterns of overlap observed in the MeSH thesaurus with respect to selected MEDLINE postings are examined. The implications of the overlap patterns are discussed, in particular, the impact of the overlap patterns on the potential effectiveness of a proposed algorithm for handling negation is considered.
