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:
“The real, then, is that which, sooner or later, information and reasoning would finally result in, and which is therefore independent of the vagaries of me and you. Thus, the very origin of the conception of reality shows that this conception essentially involves the notion of a COMMUNITY, without definite limits, and capable of a definite increase of knowledge.”
—Charles Sanders Peirce (1839–1914)
“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)
“I am both a public and a private school boy myself, having always changed schools just as the class in English in the new school was taking up Silas Marner, with the result that it was the only book in the English language that I knew until I was eighteen—but, boy, did I know Silas Marner!”
—Robert Benchley (1889–1945)
