基于Web Service的统一检索平台设计与实现

摘要

随着校园网上数字信息资源库越来越多,用户在多个库中检索需要的数据越来越难,统一检索有效地解决这个问题.介绍统一检索技术的基本原理,分析实现统一检索的几个主要问题.提出基于Web Service实现统一检索平台的技术架构,重点研究检索语法的转换方法、平台采用的缓存模型和检索结果的处理方法.最后,实现了基于校园网多资源库的统一检索原型系统,验证了提出的各项解决方案的有效性.%With the rapid increase of digital information resource libraries on the campus network, it is harder and harder for users io re-trieve required data from a number of libraries. Single search is a good way to resolve the problem. The paper introduces the basic principles of the single search technology and analyses several major problems for implementing single search. The technical architecture of the single search platform based on web service is put forward. The researches mainly include the conversion method of search expression, the data cache mode of the system and the processing method for search results. At last, a single search sy9tem on the campus network is implemented to validate the various solutions suggested in the paper.
