Knowledge base construction method and device oriented to program design field question-answering system

Abstract

The invention discloses a knowledge base construction method and device oriented to a program design field question-answering system. The method comprises the following steps that: according to the knowledge contents of an online evaluation system, preliminarily establishing an intelligent question-answering knowledge base; obtaining a user question, carrying out sentence word segmentation on thequestion, carrying out synonym replacement, and carrying out similarity calculation with contents in the knowledge base; if a user is satisfied with a current returning answer, according to question answering, synchronously updating an intelligent question-answering knowledge base, and applying a code similarity algorithm to detect data in a cache in real time; and otherwise, returning a suboptimum answer to the user until the user is satisfied. By use of the system, the problems in a traditional online after class question answering system that a time difference is in the presence, search accuracy is low, efficiency needs to be improved and the like, the information acquisition speed and accuracy of the user can be effectively improved, and meanwhile, the teaching effect of the online evaluation system is optimized.

Description

technical field [0001] The invention belongs to the technical field of computer data processing, and in particular relates to a knowledge base construction method and device for question answering systems in the programming field. Background technique [0002] The intelligent question answering system is an intelligent system based on the massive data provided by the rapidly developing Internet, through problem analysis and data processing, to answer the real problems to be solved. This system can greatly improve the speed and accuracy of users' access to information. [0003] As far as the applicant knows, the existing intelligent question answering system is mainly based on the online question answering knowledge base and the huge database in the Internet. By mining historical user question answer information and massive network data, it calculates the alignment between user question sentences and existing question answer sentences. The similarity between them returns the...

Problems solved by technology

[0004] However, the above-mentioned intelligent question answering system has the disadvantage that: due to the large differences in the grammar of different computer programming languages, the answers to the questions obtained by the system are not accurate enough in a few cases.
