Abstract—Constructing an e-portfolio platform for students is a modern educational trend. However, a student’s learning context is not analyzed in the current e-portfolio platform. In this research a model was designed for identifying the specific learning context and providing the corresponding knowledge support. A system framework which uses advanced information techniques is proposed. Information Retrieval (IR) technique extracts and analyzes key concepts from the student’s previous e-portfolio records. The data mining technique discovers hidden knowledge rules from key concepts. Various context-knowledge views were constructed based on discovered knowledge rules. Besides, Case-Based Reasoning (CBR) and profiling techniques were used to identify learning context and design adaptive knowledge recommendation mechanisms. Therefore, after identifying current learning contexts, the system would recommend previously documented knowledge to assist the student. A prototype system was developed to demonstrate the effectiveness of providing knowledge to help students solve learning problem(s).

Index Terms—e-portfolio, learning context, data mining, adaptive knowledge support.
