Research and Implementation of Fast Locating Algorithm in Intelligent QA System

摘要

With the development of network technology, E-Learning, becomes more popular, most learners want to get a right answer quickly. In order, to meet the need of learners, in this paper, firstly we construct a simple index structure based on the contents of chapters and sections according to the characteristic of E-learning, secondly, we propose a group of quick location algorithms according to the index structure, including Simple vector distance classification algorithm, Bayesian algorithm, KNN (K nearest neighbor) algorithm etc, Test results show that the algorithm can reduce the searching time about 50%, thus remarkably increase the match speed of problem and answer.
