摘要： 提出了任务的概念,每个任务代表一种知识源。不同的任务可以采用不同知识表示形式及推理策略。一个知识库由一组前向(Task)或后向链构成的任务链组成,实现了知识库的结构化、可视化,支持知识部件的重用与共享,并提供了一种知识建模机制。

Abstract: This paper puts forward the concept of task, which essentially stands for an independent knowledge source. A knowledge base can be constructed with tasks organized by forward or backward links, which implements the structuralization and visualbility of knowledge base and supports reuse and share of knowledge components as well. In addition, a modeling scheme is provided.
