ABSTRACT
The process of thesaurus evaluation can enhance the value of a thesaurus in terms of usability, scope, precision and recall. Structural, formative, observational, and comparative evaluation techniques are explained along with specific examples of their use. These methods of evaluation can be applied in the assessment of an existing thesaurus or the construction of a new thesaurus. The history of thesauri since 1960, the development of national and international standards, and sources of evaluative literature are also discussed.
