Research And Implement Of P2P Resource Search Engine Based On JXTA

Search Engine has been proved one of the most important Internetapplications. However, most of popular search engine technic suffers from anumber of shortcomings: Lacking of validation and comprehensiveness ofinformation,inaccessibility to content of "deep web" ,etc. Alternatively, a newmethod provides way for the next generation search engine--P2P basedsearching methods, which has more priority of property on real -time andvalidation than traditional searching engine.This paper First analyzes the key technology,developing trend andchallenge to the traditional SE technology. secondly, it describes a new methodbased on the advanced Peer-to-Peer distributed searching model,whichmeasures up to the orientation of SE technology's localized and distributeddevelopment. Then described how to adopt P2P method to extended the scaleof SE and improve its performance by probing into the newinformation-searching model, by comparing with the current SE based on thealgorithm of network crawler, this dissertation summarizes the advantages ofthe SE System on P2P Distributed Searching Model,which includes higherinstant Performance,deeper and wider scope of contents, higher precision insearching result and efficiency as well.Considering all P2P applications may used on different OS platforms,JXTA is adopted to build P2P share resource search engine system for it'soutstanding compatibility on the new generation developing platform of Sun,,it's deployed based on a world in which peers can take advantages of beingconnected each other and share resources despite of whatever hardware andsoftware they are using. the definition and implementation of the requiringservice has been done here grounded on the JXTA SE system in searching peernetworks,and by applying optimized VSM algorithm, it provide a newmodel of a high extensible and localizing SE system which supportedmultibyte language such as Chinese ,Uighur and so on.
