Abstract

The embodiment of the invention discloses a text summarization method and system based on deep learning, and the method comprises the steps: carrying out Chinese word segmentation and sentence segmentation processing on a target file, and dividing an original text of the target file into independent sentences; converting the original text divided into the independent sentences into text vectors; performing self-attention calculation on the text vector to obtain sentence features containing semantic information; performing weighted integration on each sentence feature obtained through out-of-order self-attention calculation, and performing normalization processing on the sentence features after weighted integration to obtain chapter-level sentence features; inputting the chapter-level sentence features into a pre-constructed classification model, and outputting sentence categories; dividing the original text of the target file into key information and non-key information according to the sentence category; and arranging and organizing the key information according to a reasonable sequence, and synthesizing the arranged and organized key information into an abstract text with smooth semantics and compliant grammar.

Description

Technical field [0001] The present invention relates to the field of artificial intelligence and natural language processing, and more particularly, relates to a text summary method and system based on deep learning. Background [0002] In recent years, textual information on the Internet has exploded due to the fact that Internet users share and transmit a large amount of information in text form on the Internet every day. When users browse massive amounts of Internet text data, it is difficult to quickly and accurately obtain the key information in it. This results in users spending a lot of time and effort to summarize the important content of the text on their own. Therefore, how to extract the content that users are most concerned about from these massive long texts and improve the efficiency of information processing has become an urgent research work in the field of natural language processing. [0003] A good abstract content needs to meet the requirements of high import...
