Procédé de composition automatique de services web, à partir d'une composition statique existante et d'une requête, ce procédé comprenant :- l'extraction de concepts dans ladite requête;- la découverte de services web dont la sémantique correspond à celle des concepts extraits de ladite requête ;- une substitution d'au moins un service web de ladite composition statique par un service web découvert ;- le séquençage des services web de ladite composition, tenant compte de ladite substitution ;- la composition des services web séquencés. The method involves extracting concepts in a query, and discovering web services whose semantic corresponds to the concepts extracted from the query. The web service of a static composition is substituted by the discovered web service. The web services of the composition are sequenced by taking account of the substitution, and the sequenced web service is composed. A main structure of a service component is constituted based on a syntactic structure of the query. Independent claims are also included for the following: (1) a computer program product comprising a set of instructions for implementing a method for automatically composition of Web services from an existing static composition and a query (2) a computer system for automatically composition of Web services from the existing static composition and the query.
