摘要	User's knowledge requirement acquisition and analysis are very important for a personalized or user-adaptive learning system. Two approaches to capture user's knowledge requirement about course content within an e-learning system are proposed and implemented in this paper. The first approach is based on the historical data accumulated by an interactive question-answering process. The association space is proposed to record and formalize the historical interactive information which is used to compute user's knowledge requirement. The second approach is based on user's reading behavior logs in the process of reading e-documents. User's reading actions including underline, highlight, circle, annotation and bookmark, are used to compute user's knowledge requirement. Two experiments are conducted to implement the two proposed approaches and acquire the user's knowledge requirement. The evaluation results show that the user models computed by two approaches are consistent and can reflect user's real knowledge requirements accurately. (C) 2009 Elsevier Ltd. All rights reserved.
