基于LDAP的分布式异构信息检索模型研究

Research of LDAP-based Heterogeneous Information Search Model

随着网上信息数量和种类的增加,传统的集中式信息检索方式已不能满足广大用户的需求,分布式信息检索技术日益成为研究的热点。以分布、异构的信息环境为背景,提出了基于LDAP目录服务的分布式异构信息检索模型。该模型具有大数据量容纳性、扩展性强、可靠性高、信息访问效率高等特点,能在异构信息环境中实现资源信息的快速定位,为用户提供快捷、方便的信息检索服务。

With the development of information technology,the technology of distributed information retrieval is increasingly becoming the hotspot of information service research.Under the distributed heterogeneous information environment,a distributed heterogeneous information retrieval model is proposed.It is based on the LDAP directory service and has the advantages of expansibility,reliability and high efficiency.It can assist the users to find needed information quickly and conveniently.
