Abstract

Several architectures, protocols, languages, and candidate standards, have been proposed to let the "semantic web'' idea take off. In particular, searching for information requires cooperation of the information providers and seekers. Past experience and history show that a successful architecture must support ease of adoption and deployment by a wide and heterogeneous population, a flexible policy to establish an acceptable cost-benefit ratio for using the system, and the growth of a cooperative distributed infrastructure with no central control. In this paper an agent-based peer-to-peer architecture is defined to support search through a flexible integration of semantic information.Two levels of integration are foreseen: strong integration of sources related to the same domain into a single information node by means of a mediator-based system; weak integration of information nodes on the basis of semantic relationships existing among concepts of different nodes.The EU IST SEWASIE project is described as an instantiation of this architecture. SEWASIE aims at implementing an advanced search engine, which will provide SMEs with intelligent access to heterogeneous information on the Internet.
