Elicitation of Preferences for Web Service Compositions.
Carolin Michels, Sudhir Kumar Agarwal · 2010
Abstract: Preference elicitation is often used in e-services to create product rec-ommendations for their customers. We present an approach for applying preference elicitation techniques for a semi-automatic query generation system for Web service compositions. These techniques are used for identifying the user’s demands on the desired Web service composition and furthermore the trade-offs between interdepen-dent or conflicting preferences. In our iterative process the query is automatically (re-)formulated to present results to the user, so that he can detect undesired character-istics and revise his specifications until he is presented a satisfiable result. 1
