Abstract

The invention discloses a junk short message new word identification method and device, and electronic equipment. The method comprises the following steps: acquiring a short message set; determining candidate word sets corresponding to the plurality of junk short messages; determining short message category tendency related indexes of the candidate words according to the short message category information; obtaining document rare related indexes of the candidate words; determining junk short message new word scores of the candidate words according to the short message category tendency relatedindexes and the document scarcity related indexes; and determining the junk short message new words from the candidate word set according to the scores of the junk short message new words. By the adoption of the processing mode, most new words recalled according to the short message category tendency related indexes have representative significance for junk short messages, and recalling of many normal vocabularies is avoided; therefore, the call accuracy can be effectively improved. Meanwhile, by means of the processing mode, low-frequency junk short message new words can be recalled according to related indexes of document scarcity; therefore, the calling full rate can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of text mining, and specifically relates to a method and device for identifying new text spam words, and electronic equipment. Background technique [0002] A typical short message sending scenario is that merchants send short messages to consumers through the network platform, so as to send information such as product promotions to consumers in a timely manner, thereby ensuring the effective implementation of merchant sales plans and improving user experience. However, along with these beneficial effects, a large number of spam messages have also appeared. The proliferation of spam text messages has seriously affected the normal life of consumers, the image of online platforms and even social stability. [0003] With the continuous development of Internet technology, more and more network platforms use SMS content security systems to analyze the content of Business-to-Customer (B2C) SMS, and perf...
