An information retrieval query language is a query language used to make queries into database, where the semantics of the query are defined not by a precise rendering of a formal syntax, but by an interpretation of the most suitable results of the query.
Of importance in IR query languages is weighting and ranking, "relevance-orientation", semantic relativism and logic-based probabilism.
An example of an IR query language is Contextual Query Language (CQL), a formal language for representing queries to Information Retrieval systems such as web indexes, bibliographic catalogs and museum collection information.
Famous quotes containing the words information, query and/or language:
“As information technology restructures the work situation, it abstracts thought from action.”
—Shoshana Zuboff (b. 1951)
“Such condition of suspended judgment indeed, in its more genial development and under felicitous culture, is but the expectation, the receptivity, of the faithful scholar, determined not to foreclose what is still a question—the “philosophic temper,” in short, for which a survival of query will be still the salt of truth, even in the most absolutely ascertained knowledge.”
—Walter Pater (1839–1894)
“All official institutions of language are repeating machines: school, sports, advertising, popular songs, news, all continually repeat the same structure, the same meaning, often the same words: the stereotype is a political fact, the major figure of ideology.”
—Roland Barthes (1915–1980)
