Information retrieval query language
From Free net encyclopedia
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.
Example: CQL stands for Common Query Language. It is a formal language for representing queries to Information Retrieval systems such as web indexes, bibliographic catalogs and museum collection information.
