The success of personalized resource discovery depends on its ability to allow users to discover, extract and integrate information of interest from heterogeneous sources, and its ability to provide these users with efficient tools to manipulate and convert the discovered information into knowledge. We propose Semantic Aware Network (SA Net), a structured peer-to-peer (P2P) overlay architecture to support the basic functionalities of a personalized resource discovery. The SA Net uses an ontology-based representation of the resources to enable a semantic resource discovery and access that reflects the interest of the user. In this paper, we describe the the SA Net search scheme "Semantic-driven Hashing" (SDH), which uses lexical-based ontology to provide a foundation for indexing and search in structured P2P overlay infrastructure.
