Abstract
The invention relates to a Chinese text recognition method and device. The method includes: acquiring keywords reported by application programs of terminals in PS domain signaling; classifying the keywords according to type of the application programs; performing segmentation, preliminary recognition and probability screening on the keywords stored in different search corpuses on the basis of different preset algorithms; adding a result acquired by screening into a preset word library. Therefore, compared with existing recognition methods, the method has the advantages that different vocabularies can be specifically processed according to type difference of the application programs reporting the keywords, higher pertinence is realized, more accurate recognition results can be acquired, andrecognition efficiency is improved.
Description
technical field [0001] The embodiment of the present invention relates to the field of software technology, in particular to a Chinese text recognition method and device. Background technique [0002] With the advent of the Internet age, people rely more and more on search engines for information retrieval. However, the traditional mechanical word segmentation method is not ideal for the recognition of ever-changing network words and emerging phrases. Chinese word segmentation technology is the basis of search engines and Chinese natural languageprocessing, and it is a major bottleneck for unregistered word recognition in Chinese word segmentation. Among them, unregistered words refer to words that have not been included in the word segmentation system. [0003] For the identification of unregistered new words, the more commonly used methods are to obtain web page content, search logs or query logs, and identify new words based on rules or statistics based on the content o...
