Abstract

The application discloses a method, a device and an electronic device for identifying new words in spam short messages. Wherein, the method includes: obtaining a short message collection; determining a plurality of candidate word sets corresponding to spam short messages; determining the short message category tendency related indicators of the candidate words according to the short message category information; and obtaining the document rarity related indicators of the candidate words; According to the related indicators of SMS category tendency and document rarity, the new word score of spam message is determined; according to the new word score of spam message, the new word of spam message is determined from the candidate word set. With this processing method, most of the new words recalled according to the related indicators of SMS category tendencies are representative of spam messages, avoiding the recall of many normal words; therefore, the recall rate can be effectively improved. At the same time, this processing method makes it possible to recall low-frequency neologisms in spam text messages according to relevant indicators of document rarity; therefore, the recall rate can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of text mining, in particular to a method and device for identifying new words in short message spam, and electronic equipment. Background technique [0002] A typical SMS sending scenario is that merchants send SMS messages to consumers through the network platform, so that information such as product promotions can be sent to consumers in a timely manner, thereby ensuring the effective implementation of the merchant's sales plan and improving user experience. However, along with these beneficial effects, a large number of spam messages have also appeared. The proliferation of spam 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 messages, and ...
