Abstract

The question answering system as a hot issue in the field of NLP study, and answer extraction as the core part of the automatic question answering system, its effect is good or bad is directly related to the performance of question answering system, this paper introduces the technical process of answer extraction module and the use of pattern matching technology, gradually shift from the traditional pattern matching technology to the machine learning method of pattern matching technology, and also calculate the questions and answers in the answer extraction module are several methods of similarity. Since the performance of the automatic question answering system depends on the algorithm used for answer extraction to a large extent, the selection of the algorithm for answer extraction is also crucial, and the accuracy of the answer returned to the user can be improved by improving the algorithm.
