Information Retrieval Query Language

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:

    I have all my life been on my guard against the information conveyed by the sense of hearing—it being one of my earliest observations, the universal inclination of humankind is to be led by the ears, and I am sometimes apt to imagine that they are given to men as they are to pitchers, purposely that they may be carried about by them.
    Mary Wortley, Lady Montagu (1689–1762)

    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)

    So runs my dream: but what am I?
    An infant crying in the night;
    An infant crying for the light:
    And with no language but a cry.
    Alfred Tennyson (1809–1892)
