Abstract
Connecting and evaluating thesauri is an important task for the systematic development of better information retrieval systems. Connecting thesauri includes not only determining when terms in different thesauri are the same but also determining what kinds of relationships can be transferred from one thesaurus to another. This paper first presents issues in connecting and evaluating thesauri. Various experiments in connecting a particular thesaurus, the Medical Subject Headings, with other medical thesauri are described. In these experiments, similar terms in two thesauri are recognized and then differences in two thesauri are exploited to create more powerful thesauri. Part of the evaluation requires the thesaurus to support automatic indexing and retrieving of documents
