One of those defects is the reuse of important and valuable discussing knowledge from asynchronous discussion boards. Nobody has time and be willing to make effort to manage the important discussion from asynchronous discussion boards in e-Learning except enthusiastic teachers or assistants. All of us know that asynchronous discussion boards is an important tool used in e-Learning for communicating and discussing with all class information for teachers and students. And reusing of important class discussing knowledge can aid teachers and students to teach and study with efficiency and effect. But up to the present, there are few researches in this domain. So, in this research we create an automatic essential content extraction method from asynchronous discussion boards in e-Learning. We explain the usage, management, and shortcomings of asynchronous discussion boards in e-Learning before. And we also describe the designing process of the research in detail. Finally, we describe the operation and the result of content extraction in this research system. All of those are hope to help teachers and students can reuse the valuable knowledge easily and quickly from past class discussion in e-Learning.
