Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0044] Such as figure 1 Shown is a flow chart of a method for generating a Chinese abstract according to an embodiment of the present invention, which specifically includes the following steps:

[0045] a) Text preprocessing: After the target text is segmented, word vectorization processing is performed, and a corresponding vocabulary is constructed, and the formed word vector sequence is used as the input of the next stage.

[0046] b) Semantic understanding: the memory function of the cyclic neural network, the word vector sequence of the first stage is input into the encoder once (using a bidirectional long-term short-term memory neural network (Bi-LSTM)), the encoder generates the semantic ...

Abstract

The invention discloses a Chinese abstract generation method and system and a storage medium, and the method comprises the steps: obtaining a target text, and determining a Chinese word vector sequence of the target text; inputting the Chinese word vector sequence into a pre-trained encoder to generate a semantic vector; reconstructing full-text semantics most suitable for the current moment according to the semantic vector, and transmitting intermediate semantics summarizing the full-text semantics after reconstruction to a pre-trained decoder; and enabling the decoder to deduce the distribution of the words at the next moment according to the words predicted at the previous moment and the intermediate semantics summarizing the full-text semantics, wherein the finally generated word sequence is the abstract of the target text. The generation quality and readability of the Chinese text abstract can be improved.

Description

technical field [0001] The invention relates to a Chinese abstract generation method, system and storage medium, belonging to the technical field of text information processing. Background technique [0002] Automatic summarization is a technology that uses computers to realize automatic text analysis, content summary and abstract generation. It is an auxiliary means to solve the current problem of information surplus. It can help humans further understand natural language texts and obtain key information more quickly, accurately and comprehensively. , has important practical significance in both industry and commerce. [0003] Currently, the commonly used summarization methods generally have the technical problems of low quality and poor readability of Chinese text summarization. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a Chinese abstract generation method, system and storage med...
