Problems solved by technology

Generative summaries are closer to the process of human-generated summaries, but they still face problems such as the lack of coherence and readability of the generated sentences, while extractive summaries copy the original text, which will generate greater redundancy and lose key information at the same time.

Embodiment Construction

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0040] In related technologies, the drawbacks of extractive summarization that have been widely studied are more prominent in long texts, especially in multiple documents. The central idea of ​​the text is usually reflected in the interrelationships between sentences, while extractive summarization generally uses word frequency, position and other information to measure the importance of keywords, and then extends to the entire sentence. This method cannot capture the text very well. Deep semantic connections between s...

Abstract

The invention discloses a text summarization method and system based on deep learning combined with an accumulated attention mechanism, and the method comprises the following steps: reading an original text through a coding and decoding framework to generate summary information, and positioning the key information of the current moment through the accumulated attention mechanism; copying key information from the original text through a pointer generation network; and inhibiting the repeated output through a coverage loss mechanism to obtain a final abstract of the original text. According to the method, an attention accumulation mechanism and a coverage loss mechanism are combined, so that the generated abstract easily grasps an article center, and the abstract has coherence and readability and does not have a repetition phenomenon.

Description

technical field [0001] The present invention relates to the technical field of text information mining, in particular to a text summarization method and system based on deep learning combined with a cumulative attention mechanism. Background technique [0002] In today's Internet environment, overwhelming network traffic floods our lives, and the explosive growth of representative text information makes the information overload, and the huge information makes people spend a lot of time browsing and reading. How to solve information overload and quickly extract key information from text data has become an urgent need. Text summarization is the epitome of the essence of document content, and it is an important tool to improve the efficiency of user search and reading comprehension. However, traditional summarization is manually generated, which is too costly and inefficient, so automatic text summarization technology came into being. [0003] According to Radev's definition, ...
