Abstract: In order to improve the accuracy of the question answering system, an intelligent question answering system for college distance education based on Chinese word segmentation technology is proposed and designed. First, the overall architecture of the intelligent question answering system for distance education in colleges and universities is designed, and then the user login display module, Chinese word segmentation module, algorithm module and other functional modules are designed. Finally, the system software is designed to optimise Chinese word segmentation technology through heuristic rules and pruning methods. The optimised Chinese word segmentation technology is applied to make the system better understand the questions or instructions input by users, and realise the intelligent question answering in college distance education. The experimental results show that after the application of this system, the accuracy rate of answering questions can reach 0.94, the highest value of TPS is 15.29, and the score range of user satisfaction is [87.4, 95.6], which has a good application effect.

Keywords: Chinese word segmentation technology; distance education; wisdom in answering questions; heuristic rules; pruning method.
