本文针对传统C/S数字图书馆模型的不足,提出一种基于语义的P2P数字图书馆模型。该模型把节点共享资源按其语义组织起来,具有相同语义资源的节点在逻辑上组成一个P2P网络,与该语义相关的查询在这个语义网络中最有可能得到快速准确的结果。 Aiming at the deficiency of the traditional C / S digital library model, this paper proposes a semantic-based P2P digital library model. The model organizes nodes’ shared resources according to their semantics. The nodes with the same semantic resources logically form a P2P network, and queries related to the semantic are most likely to get fast and accurate results in this semantic network.
