Abstract: This paper proposes a framework of task-link-based intelligent querying of information assets in peer-to-peer networks (TLB-PPIQA). It combines the features of peer-to-peer networks with ones of technology of task-link-based knowledge management to provide the capability of more flexible domain knowledge modeling and the capability of semantic-oriented, intelligent querying in decentralized environment. This paper gives emphasis on the introduction of the structure of knowledge base and the flow of intelligent query processing.

Key words: Peer-to-peer(P2P), Domain knowledge, Task, Task links, Inference engine

摘要： 提出了一种基于任务链的对等网信息智能查询体系框架（TLB-PPIQA），结合对等网和基于任务链的知识管理技术的特征，为用户提供非集中环境下更为灵活的、面向领域的知识建模能力和面向语义的、智能化的查询支持。其中重点对知识库的结构和智能查询流程进行了介绍。
