Abstract

Web service discovery aims at finding available services that match a given service description. This involves mainly the matchmaking of the functional parameters of the services, whereas non-functional attributes can also be considered and aggregated in the matching score of a candidate service as additional criteria for ranking the results. In this paper, we address the problem of re-ranking discovered services that include nominal attributes in their descriptions in order to satisfy users with diverse preferences. We present an approach to diversify the search results combining the degree of match on functional parameters with a method to achieve good coverage with respect to the values of nominal attributes. An evaluation on a publicly available dataset of Semantic Web services is also presented.
