I have just started to study this so I have not yet read some of the central literature (e.g. Hodges) on this topic. But I have discussed this at length with faculty & other doctoral students here at Univ North Carolina. That caveat aside, I rather like the typology in the NISO Z39.19 standard -- Guidelines for the Construction, Format and Management of Monolingual Controlled Vocabularies. They have 4 types and a list of criteria for them: List Ambiguity Control Synonym ring synonym control taxonomy Ambiguity Control synonym control Hierarchical relationships Thesaurus Ambiguity Control synonym control Hierarchical relationships Associative relationships And I found the definitions for the different criteria well developed and easy to understand. http://www.niso.org/standards/resources/Z39-19.html Hope this helps, Tessa -- Tessa Sullivan Ph.D student & Metadata Research Center Fellow School of Information and Library Sciences University of North Carolina, Chapel Hill tsullivan@unc.edu Luis Bermudez wrote: > > I tried to classify different controlled vocabularies in my thesis, here: > http://dspace.library.drexel.edu/handle/1860/376 (See chapter 9, page > 93).
