FuDoCS: A Web Service Composition System Based on Fuzzy Dominance for Preference Query Answering
Modern enterprises are increasingly moving towards a service oriented architecture for data sharing by putting their data sources behind services, thereby providing an interoperable way to interact with their data. This class of services is known as DaaS (Data-as-a-Service) services. DaaS Composition is a powerful solution to answer the user's complex queries by combining primitive DaaS services. User preferences are a key aspect that must be considered in the service composition process. A more general and suitable approach to model preferences is based on fuzzy sets theory. Fuzzy sets are very well suited to the interpretation of linguistic terms and constitute a convenient way for a user to express users preferences.
