Talk Abstract:
This presentation will explain the methods to design and build custom taxonomies for information retrieval. A taxonomy, as a more flexible form of thesaurus with hierarchical or categorical structures, is usually custom designed to serve a specific use case of a set of users and a set of content. As a hierarchy, the taxonomy can be built from broader to narrower terms (top down) or by grouping specific terms (bottom up). The taxonomy design must also consider the needs of the users and the subject scope of the content. We can also consider the approach of basing the taxonomy on content as building the taxonomy from the bottom up, and basing the taxonomy on the needs of the users as building the taxonomy from the top down. Various techniques in gathering terms for creating a custom taxonomy will be explained, whether the purpose for an information retrieval service, an internal enterprise taxonomy, or for a library’s special collection.
