Abstract

The embodiment of the invention discloses a sensitive word detection method and device, computer equipment and a storage medium. The method belongs to the field of artificial intelligence, and the data processed by the method can be stored in a block chain. The method comprises the steps of obtaining a sensitive word bank; constructing a harmonic word bank; constructing a sensitive word indexer and a harmonic word indexer; if the to-be-tested text is received, filtering the to-be-tested text through a sensitive word indexer to obtain a first sensitive word set; removing non-Chinese charactersin the to-be-tested text to obtain a redundancy-removed text, and filtering the redundancy-removed text through a sensitive word indexer to obtain a second sensitive word set; filtering the to-be-tested text through a harmonic word indexer to obtain a third sensitive word set; filtering the redundancy-removed text through the harmonic word indexer to obtain the fourth sensitive word set, so that sensitive words in the to-be-detected text can be recognized, deformation words of the sensitive words can also be recognized, and the recognition accuracy is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of sensitive word filtering, in particular to a sensitive word detection method, device, computer equipment and storage medium. Background technique [0002] Sensitive word filtering refers to the accurate and efficient identification of political, pornographic, insulting, prohibited, spam and other illegal content in various scenarios based on advanced artificial intelligence technology, so as to prevent content risks in advance and improve user experience. Currently, commonly used sensitive word filtering algorithms include finite automata matching algorithms based on sensitive thesaurus, classification and sequence tagging algorithms based on machine learning models. [0003] The disadvantage of the above existing sensitive word filtering method is: only the sensitive word itself can be identified, and the variant words of the sensitive word, such as homophonic words and redundant insertion words,...
