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:
“Information networks straddle the world. Nothing remains concealed. But the sheer volume of information dissolves the information. We are unable to take it all in.”
—Günther Grass (b. 1927)
“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)
“After all, when you come right down to it, how many people speak the same language even when they speak the same language?”
—Russell Hoban (b. 1925)
