Use of metadata vocabularies in data retrieval
Edwin Michael Cortez · Journal of the American Society for Information Science · 1999
Researchers have developed a prototype of a system that uses metadata to guide the user in selecting document databases of interest. A standardized vocabulary is used to index the document sets and is also used to locate databases. Once a database is located, then free-form searches are aided by the metadata vocabulary to locate specific documents. This system, the Research, Education, Economic Information System (REEIS), is being developed for the USDA to provide a way to locate programs, projects, and research that focus on food, agriculture, natural resources, and rural development.
