Abstract

An occasional sensitive word discovery method based on the word network, with the help of Internet public text data or Internet text information obtained from other channels, as well as the corresponding text language settings and the specific time of posting; the text is extracted, and the time granularity (generally set to 1 day) ) as a unit for time division, combined with the existing dictionary of common sensitive words to screen sensitive texts in a specific language, cut out several short texts according to the position of punctuation marks in the text, and perform word segmentation processing on the short texts; build a word network based on short texts , calculate the maximum K-core value of the word network, and the K-core value and core coefficient of each word in the network; for the selected core word, extract the core word within the specified historical period (generally set to 30 days) The number of times in the core position, and the average core coefficient of the time period that is not in the core position in the specified historical period, and finally use the detection formula to find the occasional sensitive words in the word network.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a word network-based discovery method for occasional sensitive words. Background technique [0002] Internet sensitive words refer to content that involves uncivilized language, etc., that is blocked by network technology or tracked by topics in real time. In today's network environment, sensitive words that have been at the core of discussions for a long time can often be detected and blocked by network technology, and these high-frequency sensitive words form a fixed dictionary of sensitive words. However, in the management of sensitive words, there are relatively few studies on occasional sensitive words. These sporadic sensitive words have never been in the fixed sensitive word dictionary, but with the evolution of some emergencies or popular topics, they will often be closely related to high-frequency sensitive words within a certain period of time, and After a certain p...
