Abstract: | Current search engines are rapidly changing to embrace more powerful mechanisms that are capable of reasoning on semantic attributes of contents in a distributed repository. Formalisms have been proposed to represent the semantic attributes. Yet, traditional approaches for content sharing in peer-to-peer systems cannot be adapted to use semantic information. Some novel proposals in the literature consider semantic aspects in P2P systems. However, they either make strong assumptions on the semantic model, or have high communication and computation overhead. |
