【摘要】 学习资源检索是网络教育资源服务的重要内容,传统搜索门户式的资源检索方式在资源的个性化服务能力、自主检索能力等方面有所欠缺。软件代理技术为实现学习资源的分布式检索、个性化服务等功能上提供了便利的途径,使实现学习资源的自主服务成为可能。利用软件代理的自主性、协作性和移动代理的迁移性特点,提出了一种基于软件代理的学习资源检索策略,研究了采用代理通信语言实现代理间通信,将检索操作指令嵌入在通信原语中,实现多代理通信与代理迁移机制相配合的分布式网上学习资源检索机制,并在此基础上实现了一个应用原型系统。更多还原

【Abstract】 Learning resource discovery is a very important service in E-Learning.Traditional resource searching service cannot provide an individualized discovery service.Software agent technology can help us to implement a distributed learning resource discovery and a individualized service.It makes it possible to search for learning resource independently.This paper introduced an agent-based learning resource discovery strategy,and implemented an experimental system.The strategy applied the agent-agent communication language and contained query instruction in the primitive performatives.Based on the strategy,we implemented a learning resource discovery system based on the strategy.更多还原
