Techniques are described for integrating semantic web services into at least one existing web service infrastructure with an execution environment by placing a proxy component between the execution environment of the existing web service infrastructure and the semantic web services so that the execution environment invoking the proxy component can interact with semantic web services, the proxy component selecting services among the semantic web services based on a predefined goal, composing an executable service from the selected services, executing the executable service and returning the result of the service execution to the execution environment. Also described are an appropriate proxy component, a system for integrating semantic web services into at least one existing web service infrastructure and a computer program.
