| 摘 要： | 传统的P2P系统是基于单特征词搜索的，且不支持语义，存在一定的局限性。提出了可变长数组模型，解决了P2P系统中多特征词搜索的问题；标识符空间的分割，使相同领域的文档在邻近的节点聚集，提高了搜索速度；本体技术的应用，使P2P系统能够理解搜索请求，有利于查全率的提高。

| Abstract: | The conventional P2P system has its limitations in that it is based on single keyword search and it does not support semantics. With Scalable Array Model, the paper attempts to realize multi - keywords search. The segmentation of identifier space helps to gather the files belonging to the same field at adjacent nodes, thus can speed up search process. In addition, Ontology Technology assists P2P system better understanding of the search and improves the recall rate. |
