Abstract
A semantic link P2P network specifies and manages semantic relationships between peers’ data schemas. The proposed approach includes a tool for constructing and maintaining P2P semantic link networks, a semantic-based peer similarity measurement approach for efficient query routing, and peer schema mapping algorithms for query reformulation and heterogeneous data integration. The advantages of the proposed approach include three aspects: First, it uses semantic links to enrich relationships between peers’ data schemas. Second, it considers not only node but also structure in measuring the similarity between schemas so as to efficiently and accurately forward queries to relevant peers. Finally, it deals with semantic heterogeneity, structural heterogeneity and data inconsistency to enable peers to exchange and translate heterogeneous information in single semantic image.
