摘　　要：为了提高网络资源索引信息动态检索系统进行检索时的覆盖范围,提出了Lucene的网络资源索引信息动态检索系统。本次设计的系统,是根据Lucene的核心逻辑,设计系统整体框架,以此调整原有的处理器,通过设计全新的网络资源分词方式,依据计算不同位置的索引信息权重来弥补原有系统的缺失。实验研究表明,与文献[2]设计的检索系统相比,Lucene的检索系统通过计算大量索引信息权重,检索得到范围更大、数量更多与用户所需内容更匹配的网络资源。由此可见,该系统的检索性能更好,可以应用到现阶段对网络资源的检索工作中。In order to improve the coverage of network resource index information dynamic retrieval system,aLucene’s network resource index information dynamic retrieval system is proposed.The design of system is based on Lucene’s core logic,the overall framework of the system is designed to adjust the original processor,the design of a new network resource word segmentation is based on calculating the weight of index information in different positions to make up for the lack of the original system.The experimental study shows that compared with the retrieval system designed in Reference[2],Lucene’s retrieval system can obtain more network resources with larger scope,more quantity and more matching content of users by calculating the weight of a large number of index information.It can be seen that the system has better retrieval performance and can be applied to the retrieval of network resources at this stage.
