With the introduction of service composition in the Web service creation, various message interactions among the atomic services result in a problem resembling the feature interaction problem in the telecommunication area. This article defines the problem as feature interaction in Web services and proposes a model checking-based detection method. In the method, the Web service description is translated to the Promela language - the input language of the model checker simple promela interpreter （SPIN）, and the specific properties, expressed as linear temporal logic（LTL） formulas, are formulated according to our classification of feature interaction.
