An implementation on instruction design ontology

Current AID (automated instruction design) platforms are criticized for incapable of transfer domain knowledge to the user intelligently owing to the lack of detailed and machine readable description of instruction design. We investigate how to apply the ontology to solve the problem. Based on former works including IMS Learning design and EML, we employ protégé to build instruction design ontology in OWL-DL (ontology web language-descriptive language). We improve the implement of activities to support ordinal relationship reasoning. We also discuss the clarity, coherence and expandability of the implementation for building one sub-class PBL (Problem-based learning). The experiments confirm our method as a feasible solution for AID semantic description.
