个性化综合倒排索引在Lucene中的应用

Application of Personalized Synthetically Inversed Index Based on Lucene

该文针对目前通用搜索引擎存在的不足，提出在建立普通倒排索引的基础上，再建立一个记录用户手动标注信息的综合倒排索引，并结合渠道奖励词频算法和文档关注度算法动态更新综合倒排索引，最后在Lucene环境下实现了一个体现用户个性的搜索引擎。

Aiming at the actual flaw of current search engine, the synthetically inverted index was built by the information which was marked by users based on building a traditional inversed index. Meanwhile, algorithms of statistical word frequency and channels and document attention algorithm were used to update the personalized synthetically inverted index. Finally, the paper designed a search engine according to users＇ personalization based on Lucene.
