Abstract

The invention discloses a question and answer pair construction method, system and device and a computer readable storage medium. The method comprises the steps of: extracting sentences of potential question and answer pairs in a text paragraph; arranging sentences of the potential question-answer pairs to generate candidate question-answer pairs; and scoring and screening the candidate question and answer pairs to obtain question and answer pairs of which the scores are higher than a set threshold. By means of the mode, the potential question and answer pairs in the document are automaticallyextracted to construct the high-quality question and answer pairs, the construction rapidness and accuracy of the question and answer pairs are improved, and the quality of the question and answer knowledge base is improved.

Description

technical field

[0001] The present invention relates to the technical fields of natural language processing and knowledge base storage, in particular to a method, system, device and computer-readable storage medium for constructing question-answer pairs. Background technique

[0002] The existing question-answer knowledge base consists of scenarios, questions, and corresponding answers. The knowledge sources of the question-answer knowledge base are mainly documents such as rule clauses and user manuals. , pets are not allowed on the high-speed rail", "the product can be returned without reason within 7 days after the product is inspected and signed for".

[0003] In the question-answering system based on question-answer pairs, the question-answer knowledge base composed of question-answer pairs is the knowledge source of the question-answer system, and the accuracy and richness of knowledge determine the quality of the question-answer system. Therefore, constructing a knowl...
