Abstract

The invention relates to a text compression method and device, a text decompression method and device, computer equipment and a storage medium. The method comprises the steps that text preprocessing is carried out on a to-be-compressed text to obtain word vectors of a plurality of target segmented words, semantic vectors corresponding to the whole text are obtained by summarizing the word vectors of the target segmented words, the semantic vectors comprise the meaning of text expression, compression is carried out through the semantic vectors of the text, a more compact representation form can be obtained, and compared with text compression according to the character frequency and the simple arrangement rule, the compression ratio can be greatly improved.

Description

technical field [0001] This application relates to the technical field of data processing, in particular to a text compression and decompression method, device, computer equipment and storage medium. Background technique [0002] Traditional compression algorithms are mainly divided into statistical coding and dictionary coding. Statistical coding mainly uses the imbalance of symbol statistical frequency and the repetition of context characters, and dictionary coding mainly uses the surface frequency and arrangement information of characters. However, if the text is compressed according to the above two encoding methods, a compressed file with a higher compression ratio cannot be obtained. Contents of the invention [0003] In order to solve the above technical problems, the present application provides a text compression and decompression method, device, computer equipment and storage medium. [0004] In the first aspect, the present application provides a text compressi...
