基于智能代理的信息检索机制在“数字城市”中的应用

Application of information searching mode based on intelligent agent in digital city

如何在海量的数据中找出我们需要的信息,是"数字城市"中急需解决的一个重要问题。在"数字成都"建设中,通过具有一定智能性的搜索策略建模,实现对元数据库的快速检索、数据的快速下载、数据的交互预览和信息缓存机制,构造由Web访问服务器和Web数据服务器两部分组成的智能代理搜索引擎,具有任务解析、数据踪迹的保留、数据缓存的特点。

Along with the development of information technology, more and more data are produced. It is an urgent problem how to find the needed data in magnanimous data. Intelligent agent is a mobile operation entity. It has four characters: agent, intelligence, autonomy and mobility. In Digital Chengdu, the intelligent agent information searching mode is used to establish the Web visit server and Web data server. Servers can realize the quick searching in metadata database, data downloading, data interviewing and data buffer memory. They have the following characteristics: task resolving, data tracing, data buffer memory.
