A Tool for Managing Domain Knowledge in Intelligent Tutoring Systems

Keywords: Information system, knowledge system, meta-data management, intelligent tutoring system. Abstract: Domain knowledge (DK) is a basic part of an intelligent tutoring system (ITS). DK usually includes information about the concepts the ITS is dealing with and the teaching material itself, which can be considered as a set of learning objects (LOs). LOs are described by a data set called learning object metadata. Concepts are usually organized in a network, called a concept network or map. Each concept is associated with a number of LOs. In this paper, we present a tool for managing both types of information in DM: creating and editing (a) a concept network and (b) learning object metadata. Additionally, the tool can produce corresponding XML descriptions for each learning object metadata. Existing tools do not offer all the above capabilities.
