Supporting discovery in virtual libraries
Bipin C. Desai · Journal of the American Society for Information Science · 1997
It is well known that selectivity leaves a lot to be desired in searching for information resources on the Internet with existing search systems (Desai, 1995c). This has prompted a number of researchers to turn their attention to the development and implementation of models for indexing and searching information resources on the Internet. In this article, 1 we examine briefly the results of a simple query on a number of existing search systems and then discuss two proposed index metadata structures for indexing and supporting search and discovery: The Dublin Core Elements List and the Semantic Header. We also present an indexing and discovery system based on the Semantic Header.
