Abstract

The embodiment of the invention provides a text compression method and a text compression device, aiming at the problems of large occupied space, low transmission speed and the like in the prior art,and realizing efficient storage and transmission of mass texts by utilizing a high-frequency coding library generated by utilizing a redundant relation of information among mass text data and a big data processing technology. The method comprises the following steps: generating a category label for a source text; searching a corresponding category coding library in a high-frequency coding libraryby utilizing the category label, the high-frequency coding library being a coding library formed by coding data of a high-frequency text block, and dividing the high-frequency text block into one or more category coding libraries according to different categories to which the high-frequency text block belongs; and performing coding serialization on the source text by using the coded data in the category coding library to obtain a compressed text.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a text compression method and device. Background technique [0002] In the process of text storage and transmission, there are usually problems such as large space occupation and slow transmission speed due to redundancy of text information and duplication of known information. Take the massive text data stored in the e-commerce mall at present, such as product snapshot data, order data, financial data, etc., and a large number of historical WEB pages, etc., as an example. Most of these huge objects may be stored directly or after traditional compression. Consumes large amounts of storage media. Therefore, effective text compression techniques are needed to avoid waste of space resources during text storage or transmission. [0003] In the prior art, text compression technology has been around for a long time, and compression algorithms are becoming more and more mature, such...
