Semantically rich descriptions of web services enable automatic composition and matchmaking. End users as well as providers compose web services according to their needs. Since in general, there can be more than one possibilities (combinations of web services) to achieve a certain goal, a user has to decide which of the alternatives suits him the best. This leads to the requirement that the combinations of web services must be comparable. This can be achieved by aggregating web service attributes. Since the ranking of web service combinations depends on user's needs, capabilities and willingness for ivestment of resources, considering user preferences is important while calculating the rank of a web service composition. We show, how user preferences as well as aggregation information can be modeled in a formal way and how web service combinations can be ranked automatically based on this information.
