LCCs are organized in a tree: The root node of this hierarchy comprises all possible topics, and leaf nodes correspond to the most specialized topic areas defined. We describe a procedure that, given a resource identified ...

This paper will explore using XSLT stylesheets to translate LCSH Authority Records from MARC/XML or MADS XML formats into RDF documents according to the SKOS project's Quick Guide to Publishing a Thesaurus on the Semantic Web.

متن کاملSuggesting Subject Headings Using Web Information Sources
We proposed a method that suggests subject headings based on user queries when a pattern-matching algorithm fails to locate subject searches for Online Public Access Catalogs (OPAC). We combined information obtained from Wikipedia, Amazon, and Google for query expansion. Our method has two main advantages: (1) availability for any library without customizing OPACs, and (2) ability to suggest su...
