In this paper, we describe SPiDeR, a peer-to-peer (P2P) based framework that supports a variety of Web service discovery operations. SPiDeR organizes the service providers into a structured P2P overlay and allows them to advertise and lookup services in a completely decentralized and dynamic manner. It supports three different kinds of search operations: For advertising and locating services, service providers can use keywords extracted from service descriptions (
keyword-based search
), categories from a global ontology (
ontology-based search
), and/or paths from the service automaton (
behavior-based search
). The users can also rate the quality of the services they use. The ratings are accumulated within the system so that users can query for the quality ratings of the discovered services. Finally, we present the performance of SPiDeR in terms of routing using a simulator.
