In this work we consider a general-purpose application for E-Commerce transactions over P2P network. Weakly organized structure of P2P systems may cause data management problems and high communication overhead. We resolve these problems by developing a novel semantic approach to efficiently create, search and organize demand and supply ads in P2P E-Commerce applications. The approach is based on the notion of Unspecified Ontology (UNSO). Unlike many existing systems, using a global predefined ontology, UNSO approach assumes that the ontology is not fully defined, leaving some parts of it to be dynamically specified by the users. The ads, inserted to the system, organize a multi-layered hypercube graph, providing an infrastructure for semantic search and routing operations. The proposed method has the potential of becoming a practical infrastructure for P2P- based publish-locate applications.
