Why do we need a thesaurus? information

UK National Biodiversity Network

The Recorder Project

BioCASE

  • Improve indexing

  • Standardise query terms for better retrieval

  • Links to synonyms and overlapping terms

  • Expand or narrow queries

  • Links to other information systems

  • Potential to build knowledge-bases

  • Potential to provide checklists for data entry

A Modified logical model

  • Principles

  • Terms fall into various ‘domains’

  • Within domains there can be many different lists

  • Lists may exist in several versions and some are dynamic (always changing)

  • Lists may be in various languages and may use a wide range of diacritic and other characters

  • There is no single correct list of terms

  • Terms frequently have synonyms, variants and language versions both in and between lists.

  • Terms commonly fall into hierarchies but may also be arranged in more complex ways (networks, ancestor & descendant trees etc.)

  • Terms can be related to terms in other domains

The logical model can be expressed in many ways software to check for terms not in master thesaurus or get added value data

We may change the physical model as we learn more or for performance reasons. We use an API (Application Programming Interface) to shield users from underlying complexity and change.
