Structured vocabularies for information retrieval – Guide
The ability to identify and locate relevant information among vast
collections and other resources is a major and pressing challenge today
Several different types of vocabulary are in use for this purpose. Som
of the most widely used vocabularies were designed a hundred years ag
and have been evolving steadily. A different generation of vocabularie
is now emerging, designed to exploit the electronic media more
effectively. A good understanding of the previous generation is still
essential for effective access to collections indexed with them.
An important object of BS 8723 as a whole is to support data exchang
and other forms of interoperability in circumstances in which more tha
one structured vocabulary is applied within one retrieval system or
network. Sometimes one vocabulary has to be mapped to another, an
it is important to understand both the potential and the limitations of
such mappings. In other systems, a thesaurus is mapped to a
classification scheme, or an ontology to a thesaurus. Comprehensive
interoperability needs to cover the whole range of vocabulary types,
whether young or old.
