Question matching system and question matching system in intelligent interaction system

Abstract

The invention discloses a question matching system and a question matching system in an intelligent interaction system. The question matching method comprises the following steps of performing word segmentation, stop word removal and query expansion on a question asked by a user to avoid interferences of small correlation in a complex sentence to question matching results; according to a preset index file, matching a candidate question associated with the questioning question in a question and answer database, and reducing question matching calculation amount; then, calculating the similarity of the questioning question with the question in a similar question set corresponding to the candidate question, thereby avoiding a condition that same questions are not matched with questions due to a plurality of different asking methods, and improving the question matching results; finally, according to the calculated similarity, outputting an answer corresponding to the question matched with the questioning question according to a preset rule. According to the whole scheme, the accuracy rate of the question matching results in the intelligent interaction system is increased.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a question matching method and system in an intelligent interactive system. Background technique [0002] The most important step in the intelligent interactive system is to match the similarity between the question raised by the user and each question in the question-and-answer database (hereinafter referred to as the question-and-answer database), and then find out the question with the highest similarity and output the corresponding answer. Most of the existing methods are to calculate the similarity of words first, and then combine the position, weight, dependency relationship and other characteristics of words to finally calculate the similarity of sentences. However, the existing technologies do not have ideal problem matching results in domain-specific intelligent interactive systems. [0003] The main reasons are as follows: [0004] (1) The same question can be as...
