 |
Thesaurus is only available from OpenKM 5.0 and upper. |
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 configure correctly OpenKM thesaurus you must set this OpenKM.cfg entries:
kea.thesaurus.owl.file kea.thesaurus.base.url kea.thesaurus.tree.root kea.thesaurus.tree.childs
Set OWL file
kea.thesaurus.owl.file=/vocabulary/file.owl
Set base url
kea.thesaurus.base.url=http://www.someweb.org
Query to get root node
kea.thesaurus.tree.root=SELECT DISTINCT UID, TEXT FROM {UID} Y {OBJECT}, {UID} rdfs:label {TEXT} ; [rdfs:subClassOf {CLAZZ}] where not bound(CLAZZ)
and lang(TEXT)="en" USING NAMESPACE foaf=<http://xmlns.com/foaf/0.1/>, dcterms=<http://purl.org/dc/terms/>,

Query to get childs node
kea.thesaurus.tree.childs=SELECT DISTINCT UID, TEXT FROM {UID} rdfs:subClassOf {CLAZZ}, {UID} rdfs:label {TEXT} where xsd:string(CLAZZ) =
