Problems solved by technology

[0003] However, the number of extended questions formed by the above-mentioned method of generating extended questions in the prior art is limited; in addition, there are invalid extended questions in the formed extended questions, which occupy system resources and cause user questions to be unable to be compared with standard questions and standard questions. Extended question matching, affecting the accuracy of question answering

Embodiment Construction

[0046] As mentioned in the background technology, the number of extended questions formed by the above-mentioned method of generating extended questions in the prior art is limited; in addition, there are invalid extended questions in the formed extended questions, occupying system resources, and causing user problems to fail. Matches with standard questions and extended questions, affecting the accuracy of question and answer.

[0047] In the technical solution of the present invention, since each word corresponds to a large number of related words, a large number of extended questions can be obtained by replacing the original words in the extended questions with related words; Judging the validity of the combination between the adjacent words of the above related words to filter invalid extended questions, thus ensuring the validity of the formed extended questions; and then ensuring that the formed extended questions can match the user's questions , to improve the timelines...

Abstract

The invention discloses a question extension method and device, a storage medium and a terminal. The question extension method comprises the steps of obtaining a question to be extended, performing word segmentation on the question to be extended to obtain multiple original words; performing related word substitution on the multiple original words so as to obtain multiple extended questions obtained by combining the original words and the related words or combining the related words; judging the effectiveness of the combination of the related words and adjacent words in each extended question;according to the judgment result, filtering the multiple extended questions. According to the technical scheme, the extended questions can be automatically generated, and the effectiveness of the extended questions is ensured.

Description

technical field [0001] The present invention relates to the technical field of natural language processing, and in particular to a question extension method and device, a storage medium, and a terminal. Background technique [0002] In the prior art, a knowledge base for question answering usually includes multiple knowledge points, and each knowledge point includes a standard question, an extended question sentence corresponding to the standard question, and an answer. In order to achieve the accuracy of question answering, it is necessary to expand the standard questions in the knowledge base to form as many extended questions as possible. Extended questions in knowledge bases usually need to be written manually. Or use semantic templates and semantic expressions to generate extended questions. [0003] However, the number of extended questions formed by the above-mentioned method of generating extended questions in the prior art is limited; in addition, there are invali...
