Maceio, Brazil: Proceedings of the 2nd International Workshop on Applications of Semantic Web for E-learning held at the ITS 2004 Conference, 30 Aug-3 Sep 2004. 41-49.978-3-540-22948-3http://hdl.handle.net/10092/339Acquiring the domain knowledge is a task that requires a major portion of the time and effort when building an ITS. Researchers have been exploring ways of automating the knowledge acquisition process since the inception of ITSs with limited success. All past research attempts have focussed on acquiring knowledge for procedural domains. Our goal is to develop an authoring system that acquires knowledge for procedural as well as nonprocedural domains. We propose a four phase approach: composing an ontology of the domain, extracting syntax constraint from it, learning semantic constraints from the examples provided by the domain expert and finally verifying the generated constraints. This paper presents an overview of the knowledge acquisition system for acquiring knowledge for constraint-based tutors. It mainly focuses on composing the ontology and acquiring syntax constraints from it. Further work on this project will focus on learning from examples and validating the generated constraints.enConference Contributions - PublishedFields of Research::280000 Information, Computing and Communication Sciences::280200 Artificial Intelligence and Signal and Image Processing::280201 Expert systemsFields of Research::280000 Information, Computing and Communication Sciences::280100 Information Systems::280104 Computer-human interaction
