智能教学系统（Intelligent Tutoring Systems，ITS）是一种流行的智能教育系统。领域知识（DK）是ITS的基本组成部分，通常包括ITS所处理的概念和教材本身的信息。教材由一组学习对象（LO）组成。LO由称为其元数据的数据集描述。概念通常被组织在一个网络中，称为概念网络（或地图）。每个概念都与若干联络处有关。现有的知识库管理工具主要处理联络处或概念，但不处理它们之间的联系。在本文中，我们提出了一个工具，用于管理这两种类型的信息在DK：创建和编辑一个概念网络和LO元数据，以及连接它们。此外，该工具可以为每个LO元数据生成相应的XML描述。最后，它提供了帮助教师组织和编写课程的设施。小规模评价表明，该工具的可接受性令人满意。
Intelligent Tutoring Systems (ITSs) constitute a popular type of intelligent educational systems. Domain Knowledge (DK) is a basic part of an ITS and usually includes information about the concepts the ITS is dealing with and the teaching material itself. The teaching material consists of a set of learning objects (LOs). A LO is described by a data set called its metadata. Concepts are usually organized in a network, called a concept network (or map). Each concept is associated with a number of LOs. Existing tools for managing DK mainly deal with either LOs or concepts, but not with connecting them. In this paper, we present a tool for managing both types of information in DK: creating and editing a concept network and LO metadata as well as connecting them. Additionally, the tool can produce corresponding XML descriptions for each LO metadata. Finally, it provides facilities for helping tutors in organizing and composing their lessons. A small scale evaluation has shown more than satisfactory acceptability of the tool.
