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 described best practice for the basic elements needed in nearly all thesauri: concepts, terms (preferred and non-preferred), and standard relationships. The focus was on why these and other features were needed. The session concluded with a critical look at the strengths and weaknesses of the thesaurus in today’s context.

The class was delivered via Zoom and was attended by 91 participants from 25 countries. Presentation slides are available to all participants via the KO-ED forum on the ISKO UK website.
