Satellite internet text sensitive information detection method and device based on deep learning

Abstract

The embodiment of the invention discloses a satellite internet text sensitive information detection method and device based on deep learning. The satellite internet text sensitive information detection method based on deep learning comprises the steps: carrying out sensitive word detection on a target text, and determining sensitive words in the target text, wherein the target text is transmittedthrough the satellite internet; based on the context of the sensitive word, determining an emotional tendency type of the target text by utilizing a trained FastText model, wherein the emotional tendency type comprises a first tendency type and a second tendency type; and based on the target text of the second tendency type, generating the target text abstract by using a trained neural network model. According to the embodiment of the invention, sensitive word detection and emotional tendency classification are combined, misjudgment on the target text is reduced, and the target text with relatively long content is changed into the target text abstract with relatively short content through the neural network model, so that the accuracy and efficiency of sensitive information detection are effectively improved.

Description

Technical field [0001] The present disclosure relates to the technical field of natural language processing, and in particular to a method and device for detecting sensitive satellite Internet text information based on deep learning. Background technique [0002] Satellite Internet refers to a network system based on a satellite communication system that uses Internet Protocol Address (IP) as a network service platform and Internet applications as a service object. It can become an integral part of the Internet and can operate independently. At present, the rapid development of foreign commercial satellite Internet has the characteristics of operating platforms deployed abroad and the transmission network has no obvious physical boundaries. This has increased the difficulty of satellite network management and control. The best way to control the satellite Internet is not to block its connection, but to selectively block or limit it. Therefore, it is required to analyze the text i...

Problems solved by technology

[0004] Although the research on sensitive information detection methods has made great progress, there are still many problems to be solved due to the complexity of text information in satellite Internet

The challenges of sensitive information detection mainly include several aspects: (1) For the text with sensitive words, it cannot be judged that it contains bad information just by containing sensitive words, but also needs to be combined with the context semantics of sensitive words to judge the intention of the text, otherwise it will cause misjudgment; (2) For texts with a lot of content, and the context associated with sensitive words is long, it is difficult to judge its semantics through traditional natural language processing methods. In order to reduce misjudgments, manual intervention is required; (3) ) The cost of manual intervention in judgment is too high, because for long texts, manual reading takes a long time, which seriously affects the efficiency of judgment
