Problems solved by technology

The generation of traditional question templates requires manual template setting for specific sentence patterns, which is not only cumbersome but also poor in coverage; when the knowledge base is updated, it is also necessary to manually set new templates for question templates that cannot be covered in the template library Poor with evaluation, maintainability and self-learning
In the relevant patents disclosed so far, no corresponding improvement technical solutions have been found for the above technical problems. For example, the invention application 201611076382.1 ("A Method and Device for Automatic Question-Answer Template Matching"), by determining the templates corresponding to each participle of the question to be answered A subset of the question set to get the matching questions of the questions to be answered, which improves the template matching efficiency and accuracy of the automatic question answering system, but does not involve the automatic generation of templates and the quality assessment of generated templates

Embodiment 1

[0061] figure 1 It is a flow chart of the method for automatically generating question sentence templates provided by the embodiment of the present invention. Such as figure 1 As shown, the question template automatic generation method that the embodiment of the present invention provides, comprises the following steps:

[0062] 101. Prepare question log corpus.

[0063] Specifically, the question log corpus is obtained, and the question log corpus is preprocessed, including but not limited to punctuation removal, illegal symbol removal, word case conversion, and the like.

[0064] 102. Perform word segmentation and part-of-speech tagging on the log corpus.

[0065] Specifically, the log corpus is segmented in combination with the word segmentation method of the industry dictionary. According to different needs or industries, different types of industry dictionaries can be created. Especially when it comes to specific vertical industries, using the word segmentation method...

Abstract

The invention discloses a question sentence template automatic generation method and apparatus, and belongs to the technical field of intelligent question and answer. The method comprises the steps ofpreparing question sentence log corpora; performing word segmentation and part-of-speech tagging on the log corpora; performing named entity identification and replacement; performing semantic replacement; and performing frequent item set mining, and generating a question sentence template. According to the method and the apparatus, the question sentence template generation efficiency is improved; a large amount of labor resources are saved; the generated question sentence template can be assessed; a question sentence template library is autonomously and continuously expanded; and the qualityof a knowledge base of an intelligent question and answer system is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent question answering, in particular to a method and device for automatically generating question sentence templates. Background technique [0002] At present, more and more companies will undertake a large number of after-sales service or pre-sales consulting work for users. Due to the exponential growth of the number of users, it will consume a lot of human resources to answer all user inquiries completely manually, and many knowledge points are relatively concentrated, and manual responses often involve a lot of repetitive work, so the intelligent question answering system came into being, intelligent question answering The system can automatically answer the questions entered by the user, and the efficiency has been greatly improved. [0003] The technical principles of the intelligent question answering system are based on question template matching and knowledge base retrieval. Among them...
