Beyond state of the art Feature State of the art Improvement Architecture for lightweight semantic service discovery Approaches based on a registration process or an editorial team Enables to scale service discovery with the upcoming increase of publicly available services Largest and most accurate set of publicly available services Specialized portals only containing subset of services Focused crawler able to identify services and related information Automatic metadata creation for Web Service Innovative; under-researched Metadata generation from Web 2.0 data and services Integration of formal and informal (textual) knowledge Indexed textual descriptions Hybrid match-making algorithm Automatic creation of both user and service clusters Only general-purpose clustering techniques exist Specialize clustering algorithms that jointly cluster users and services Innovative interface that combines Web 2.0 features and service related features Current Web 2.0 portals do not include semantic metadata. Techniques that enable handling of semantic metadata in Web 2.0 portals
