Abstract

The invention relates to a method for obtaining question and answer pairs from an unstructured text based on deep learning. The method comprises the following steps of performing text normalization processing; based on a deep neural network model, sentence classification and pairing and key phrase extraction are carried out; obtaining question and answer pairs in the text; crawling question and answer pairs outside the text; question and answer pair summary duplicate removal. According to the method, for the problem that question and answer pairs are difficult to obtain, the scale question andanswer pairs are automatically and efficiently obtained by effectively utilizing easily-obtained unstructured document resources in combination with the use of the deep neural network model for manual proofreading and supplementary use, so that the knowledge base construction cost is reduced, and the knowledge base construction speed is increased.

Description

technical field [0001] The present invention relates to the technical field of natural language question answering system knowledge extraction, in particular to the field of question answer pair extraction, specifically a method for obtaining question answer pairs from unstructured text based on deep learning. Background technique [0002] Natural language processing (NLP, natural language processing) is a field of computer science, artificial intelligence, and linguistics that focuses on the interaction between computers and human (natural) language. It is an important direction in the field of computer science and artificial intelligence. [0003] Natural language processing is a science that integrates linguistics, computer science, and mathematics. The research in this field will involve natural language, that is, the language that people use every day, so it is closely related to the study of linguistics. There are important differences. Natural language processing is ...
