翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Information retrieval query language ： ウィキペディア英語版 Information retrieval query language An information retrieval (IR) 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. ==See also== *Controlled vocabulary *Free text searching *Information retrieval *SQL *Text retrieval *Database query language 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Information retrieval query language」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
