Abstract

The invention discloses a data processing method and device for text recognition. The method includes: acquiring target words in a corpus; acquiring reference words in the corpus; converting the target words into word vectors to obtain target work vectors; converting the reference words into word vectors to obtain reference word vectors; calculating the similarity of the target word vectors and the reference word vectors; comparing the similarity with a preset threshold; determining the target words as background noise words if the similarity is not larger than the preset threshold; determining that the target words are not the background noise words if the similarity is larger than the preset threshold. By the method, the problem that background noise word filter in the prior art is low in accuracy is solved, and background noise word filter accuracy is further increased.

Description

technical field [0001] The present invention relates to the field of natural language processing, in particular to a data processing method and device for text recognition. Background technique [0002] In order to save storage space and improve search efficiency, search engines will automatically ignore certain words or words when indexing pages or processing search requests. These words or words are called stop words (Stop Words). Usually, stop words can be roughly divided into the following two categories: One type of stop words refers to words that are widely used and can be seen everywhere on the Internet, such as the word "Web" that appears on almost every website. Search engines cannot guarantee that they can give truly relevant search results, and it is difficult to help narrow the search scope, and at the same time reduce the efficiency of search; another type of stop words refers to modal particles, adverbs, prepositions, conjunctions, etc., usually these words the...
