Starting with the easy steps. Synonym Rings and Authority Files – In part 3 of the continuing series on controlled vocabularies and faceted classification, the CV tagteam champs Karl Fast, Mike Steckel, and Fred Leise explain synonym rings and authority files and how their use can bridge the gap between natural language and complex controlled vocabularies (taxonomies and thesauri). The techniques presented, unlike the complications of full faceted schemes or ontologies, are accessible and feasible for a wide variety of projects. Worth checking out if you're wanting to implement a lightweight approach to vocabulary control. [Boxes and Arrows] [ia/ – information architecture news]
