成果地质资料检索系统研究与实现

Research and Implementation of the Results Geological Data Retrieval System

传统的成果地质资料查询服务系统是基于数据库查询设计的,以项目档案的标题和内容摘要为主进行查询,存在借阅者查找资料时间长,检索精度不高,甚至漏检部分资料的问题,为此,本文重新设计并实现了成果地质资料检索系统。通过对汇交的项目文档进行处理,建立索引,利用全文检索技术提升搜索结果的召回率;基于本体和搜索日志,使用查询扩展技术提升搜索结果的准确率。经资料馆应用证明,该系统节约了借阅者寻找资料的时间,提高了检索性能,增强了资料馆的服务能力。

Traditional results geological information search service systems are designed based on database inquiries withpriorities given to queries with title and content abstract of the project archives. They have the problems with long runningtime, low retrieval accuracy, meanwhile with unretrieved data. This paper designs and implements a retrieval system forresults geological data. By processing and indexing documents, full-text retrieval technology are applied and recall ratesof search results are enhanced. On the other hand, based on ontologies and search logs, query expansion technologies areimplemented to promote the accuracy search results. The application in library indicates that the system saves running timeof searching for data and improves the retrieval performance, enhancing the library service ability.
