In the recent years distributed architectures and P2P technology have been adopted to better support effective collaboration among networked organizations. According to the P2P paradigm, many autonomous peers need to cooperate under highly dynamic conditions by sharing their resources (such as data and services), without sharing a common semantic model or ontology and without having a-priori knowledge about each other. In such a scenario, for effective collaboration, new advanced tools are required to support semantic representation and discovery of distributed resources such as data and services. In this paper we focus on semantic collaboration and service discovery in P2P systems. We propose the construction of a service semantic overlay over the P2P network, that is, a dynamic conceptual map across peers that provide similar services and constitute synergic service centers.
