Glossary » relevance


in search, relevance is a measure of the quality of a search result, indicating how close the search result is to the information being sought. Relevance is often measured, for instance, by the number of times a search term occurs in a document relative to the length of the document. Many other factors may be considered, such as: frequency of synonyms and related terms, overall popularity of the document, links to the document from other “relevant” documents, expert ratings of relevance, quality of the document, or explicitly defined keywords in the document that match the search term.
