What is a thesaurus? How and why so?
Building on the theory and basic principles set out in earlier sessions of this series, Stella Dextre Clarke will present a practical perspective on thesauri for information retrieval (IR). Guidance in the prime national and international standards, culminating in ISO 25964, provides the underlying frame of reference. After a reminder of the historical context in which the IR thesaurus was originally conceived, the session describes best practice for the basic elements needed in nearly all thesauri: concepts, terms (preferred and non-preferred), and standard relationships. The focus will be on why these and other features are needed. The session concludes with a critical look at the strengths and weaknesses of the thesaurus in today’s context.
