基于Internet的DOL教材信息发现和收集Agent

介绍一个基于多Ａｇｅｎｔ（ｍｕｌｔｉ－ａｇｅｎｔ）体系结构的信息检索系统：ＤＯＬＴＲＩ－Ａｇｅｎｔ．ＤＯＬＴＲＩ－Ａｇｅｎｔ用于从Ｉｎｔｅｒｎｅｔ上发现和收集用于远程开放教学（ＤｉｓｔａｎｃｅａｎｄＯｐｅｎＬｅａｒｎｉｎｇ，简称ＤＯＬ）中进行教材设计的教材信息．ＤＯＬＴＲＩ－Ａｇｅｎｔ根据用户需要和任务模型主动、智能和协作地搜索Ｉｎｔｅｒｎｅｔ上的各种信息资源（如数据库，ＷＷＷ服务器等），对搜集到的教材信息归类存储，实时地更新本地教材信息库以与外部信息源保持动态一致．它还接收Ｉｎｔｅｒｎｅｔ信息空间中其他教材信息搜集Ａｇｅｎｔ和其他类型Ａｇｅｎｔ的服务请求，开放地与其他Ａｇｅｎｔ进行互操作，实现信息共享和交流

A SOFTWARE AGENT FOR INTERNET BASED DOL TRAINING RESOURCE INFORMATION DISCOVERING AND GATHERING

This paper introduces an information retrieval system named DOLTRI Agent adopting multi agent architecture. DOLTRI Agent discovers and gathers training resource information from Internet information space for the design of training resources for distance and open learning(Abbr. DOL). DOLTRI Agent intelligently, autonomously and collaboratively searches, filters and fuses various information sources(i.e., database, WWW server, etc.)on the Internet according to the user's need and the task model, classifies the retrieved information and updates the training resource information library to dynamically keep consistent with the outer information sources in Internet information space. It can collaborate with other agents in Internet information space for information communication and sharing.
