Abstract: A method for detecting SQL injection interception is provided. The method includes: detecting a received SQL instruction according to a SQL syntax tree rule to determine that the received SQL instruction is a malicious instruction; and analyzing the received SQL instruction by using an analysis model to determine that the received SQL instruction is a potentially malicious instruction, in a case that the received SQL instruction is not determined to be a malicious instruction according to the SQL syntax tree rule. The method can combine the online detection and the offline analysis to intercept the invading malicious SQL commands, and can also find and supplement the loopholes of the rules through offline analysis.

Abstract: A public opinion acquisition method and device, a word viscosity model training method and device, a server, and a medium are provided in the present disclosure. And the present disclosure relates to the technical field of artificial intelligence, specifically to image recognition and natural language processing, which can be used in a cloud platform. A video public opinion acquisition method includes: receiving a public opinion acquisition request, the public opinion acquisition request including a public opinion keyword to be acquired; matching the public opinion keyword to be acquired with video data including a recognition result, wherein the recognition result is obtained by performing predefined content recognition on the video data, the predefined content recognition including text recognition and image recognition; and determining video data that matches with the public opinion keyword to be acquired as result video data.
