文献搜索引擎中特征项及权重的应用

摘要

针对目前用户在使用搜索引擎过程中，检索结果冗余、效率低下等问题，本文在对文献垂直搜索系统中Lucene.Net 的索引算法研究基础上，结合用户实际专业检索需求，改变其算法中的激励因子，实验结果证明该方法确能提高搜索结果的相关度.%As the Web continues to grow, it has become increasingly obvious that information overload, low-efficiency using traditional search engines. In this paper, after researching the index sort algorithm applied in the Lucene.Net and considering the requirement from the end-users, we present an approach to address this issue. The experimental results showed that the proposed approach is practical.
