Abstract

The invention relates to the technical field of data search and particularly relates to a classified error correction method and a classified error correction device. The method comprises the following steps: generating a keyword list corresponding to an information category on the basis of the information category; generating an error word set for classified information corresponding to the information category according to the keyword list corresponding to the information category; classifying the classified information, generating a positive word set and a negative word set corresponding to the classified information; correcting errors of the positive word set and the negative word set of the classified information according to the error word set for the classified information. According to the classified error correction method and the classified error correction device, the classifying result is more accurate, and the information acquired by a user is more accurate, so that the user is effectively helped to search.

Description

technical field [0001] The invention relates to the technical field of data search, in particular to a classification error correction method and device. Background technique [0002] With the development of Internet technology, the amount of data in the network is becoming larger and larger. At present, a large number of network resources are usually divided into different categories. For example, a large amount of video information in websites is usually divided into multiple categories such as sports, movies, TV, music, etc. , the existing technology can provide a list of keywords or hot words corresponding to each category, and users can quickly understand the core and popular content under the current category by browsing the list, so as to help users search for the content they are interested in. [0003] Extracting keywords or hot words of a certain category usually involves text mining, machine learning and other fields, such as classifying text through Support Vecto...
