Abstract

The application discloses a method and device for text matching. The method comprises the steps that at least two pieces of word attribute information of each to-be-processed text among multiple to-be-processed texts are acquired, wherein multiple to-be-processed texts comprise at least a to-be-matched text and multiple pre-stored texts in a text library, and each piece of word attribute information is used to record an index relation between a word contained by the to-be-processed text and the to-be-processed text; word attribute information corresponding to the word attribute information of the to-be-matched text is extracted from the word attribute information of the multiple pre-stored texts; and based on the index relations recorded in the extracted word attribute information, a matched text matched with the to-be-matched text in the multiple pre-stored texts is determined, wherein the word attribute information of the to-be-matched text and the matched text could be matched entirely or partially. According to the invention, the technical problem that matching results of text matching methods are not accurate can be solved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a text matching method and device. Background technique [0002] In the prior art, web page rearrangement and text information matching can be performed through a hash algorithm. Locality Sensitive Hash Algorithm among the existing Hash Algorithms realizes text information matching. [0003] Specifically, local sensitive hash (LSH) is a hash algorithm that puts similar states or adjacent points in a high-dimensional space into the same bucket, and is generally used for similar text processing. MinHash in local sensitive hashing uses the hash value of a word in the text to represent the state of the text. When matching two texts, the state of the two texts is matched, that is, based on the hash value of the two words The hash value matches two texts, and if the hash values ​​of the two words are consistent, the two texts are considered to be matching texts. Using this m...
