Knowledge base establishment method of program design class course post-class question answering system

Abstract

A knowledge base establishment method of a program design class course post-class question answering system comprises the following steps of S1, obtaining and sorting the received question statementsaccording to the interactive information; S2, generating a word vector matrix of the question statement, and judging the question type of the question statement through a preset model; S3, calculatingthe semantic similarity between the question statements and other question statements of the same type; and S4, constructing candidate answers according to the semantic similarity, sorting the candidate answers through a sorting algorithm, and updating the knowledge base of the question statement. According to the method, the type of a question statement is judged by using a model, the candidateanswers are constructed according to the semantic similarity among similar statements, and finally the knowledge base of the question statements is constructed by sorting the candidate answers throughthe sorting algorithm, so that the performance of the post-class question answering system is better.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a method for establishing a knowledge base of an after-school question answering system for programming courses. Background technique [0002] At present, the automatic answering system of distance education is mainly based on Web BBS discussion, message board and Email communication, which has problems such as long time delay and low efficiency. In the after-school question answering system with certain intelligence, take the Answer Web automatic question answering system developed by Shanghai Jiaotong University as an example. However, the after-class Q & A of similar courses did not perform well, and could not provide students with better answers. This is caused by the particularity of programming courses. The difference between programming courses and other professional courses is that programming courses involve a series of professional issues...
