摘要
针对目前OA资源全文检索系统的现状,分析研究全文检索的搜索引擎开源框架库Lucene,提出并实现基于Lucene对OA资源进行全文检索的方法,并从检索速度和检索质量两方面与Google桌面全文检索进行比较。测试结果表明,基于Lucene的全文检索速度较Google桌面全文检索稍慢,但查准率高于Google桌面全文检索,完全可以满足用户的需求。
The paper presents the current status of full text retrieval system of the Open Access（OA） resources and ana- lyzes the open source library Lueene of full text retrieval engine. Then it proposes and implements the method of full text retrieval based on Lucene of OA resources. At last, it also compares the system with Google Desktop search engine in speed and quality. The results of test show that the system is a bit slower than the Google Desktop, and the precision rate is higher than that of Google Desktop. So the full text retrieval system based on Lucene can fully meet the needs of users.
