增强信息系统的检索功能:一种基于Agent的通用方法

分析了基于RDBMS所开发的信息系统查询功能方面的不足及其原因，提出了一种利用全文检索技术与Agent技术来增强和完善该类查询系统检索功能的方法，并建立了一个支持该方法的模型。通过一个具体的实例介绍了该方法的设计与实现过程。对采用该方法前后实例系统的检索性能（检索响应速度）进行了深入的对比与分析。结果证明该方法是有效的、可靠的和有实用价值的，可有效增强图书馆书目查询，旅游地址查询、CBD（Case Based Design)中的实例检索等一类系统的检索功能。

Enhancing the Query Function in Information Systems:An Agent-Based General Approach

This paper, firstly, analyzes the shortages of the query subsystem of some information systems based on RDBMS as well as the reasons that cause them. Then, it presents a new approach to overcome these shortages and to enforce the system by means of full text retrieval and agent technologies. The general model of the approach is introduced. An instance, which makes use of the presented general model, is introduced. And then its' performance is tested, analyzed and compared with old systems in detail. The test results and analysis show that this new approach is useful, viable for most information systems such as library bibliographic query systems, CBD retrieval systems,etc.
