Nota clasica.png Thesaurus is only available from OpenKM 5.0 and upper.

A thesaurus is a book that lists words grouped together according to similarity of meaning (containing synonyms and sometimes antonyms), in contrast to a dictionary, which contains definitions and pronunciations.


In Information Science, Library Science, and Information Technology, specialized thesauri are designed for information retrieval. They are a type of controlled vocabulary, for indexing or tagging purposes. If you want more information about term you can take a look at http://en.wikipedia.org/wiki/Thesaurus


OpenKM can working with thesaurus defined in .owl and .rdfs formats.


There's a great utility http://protege.stanford.edu/ to create and maintaining your own thesaurus. In Internet can be found specific thesaurus, for example Agrovoc[1] ( FAO ), NASA Thesuarus[2], UNESCO Thesaurus[3], Public administration Thesaurus[4] among others. Someones are free and others have some usage restrictions.


In order to correctly configure OpenKM thesaurus you must set this OpenKM.cfg entries:

kea.thesaurus.skos.file
kea.thesaurus.owl.file
kea.thesaurus.base.url
kea.thesaurus.tree.childs
