Information detection method and device

The invention provides an information detection method and an information detection device. The information detection method comprises the steps of obtaining text information of to-be-detected information; comparing the text information with first attributive words in a multiattribute thesaurus, wherein the first attributive words include key words and anagrams of the key words; comparing five characters in front of the first attributive words and five characters behind the first attributive words in the text information with second attributive words in the multiattribute thesaurus when the text information contains the first attributive words, so as to obtain a comparison result, wherein the second attributive words are determiners of the key words; determining whether the text information is illegal information according to the comparison result. Compared with the prior art, the information detection method has the advantages that the illegal information is determined by comparing different words, so that the text information can be completely detected, and the probability of incorrect determination caused by single key words is reduced, and the information detection accuracy is increased.
