For the analysis, we extracted about 833,000 query keywords from NDSL search logs during nearly 17 months and approximately 41,000,000 technical terms from NDSL, INSPEC, FSTA journals. And we used only the English noun phrase in extracted those and then we did an experiment on analysis of equality, relationship analysis and frequency analysis.

In order to index documents, a thesaurus which consists of terms and relationships between terms is used. When an index term is selected, retrieval performance in the information retrieval system could be improved by using the relationship between the terms in the thesaurus. Recently, the usage of a thesaurus are extended from information retrieval to language and knowledge engineering, but term relationships in a thesaurus are simply represented in equivalence, hierarchy, and association. Particularly the associative relationship is vague in its definition and range as compared with the other relationships, i.e. equivalence, hierarchy, therefore the terms that are selected through associative relationship aren't well controlled. This study examines the relationships of existing thesauri, especially the types and ranges of associative relationship, and suggests the adequate type of associative relationship.
