Document Searching System based on Natural Language Query Processing for Vietnam Open Courseware Library

The necessary of buiding the searching system being able to support users expressing their searching by natural language queries is very important and opens the researching direction with many potential. It combines the traditional methods of information retrieval and the researching of Question Answering (QA). In this paper, we introduce a searching system built by us for searching courses on the Vietnam OpenCourseWare Program (VOCW). It can be considered as the first tool to be able to perform the user’s Vietnamese questions. The experiment results are rather good when we evaluate this system on the precision and the run-time of answering the Vietnamese questions.
