Abstract

The present invention is applicable to the technical field of network public opinion early warning, and discloses a public opinion early warning method based on unstructured data. The method comprises: using crawler tools to obtain corresponding time series data on the Internet, and preprocessing the data; carrying out association processing on structured data and unstructured data of a same event; and automatically annotating the unstructured data by analyzing the structured data, and extracting features of the time series unstructured data by using a deep learning method. Thus, according to the method disclosed by the present invention, shortcomings of current unstructured data processing requires a large number of man-made annotations, has costly human resources and material resources, and has high processing difficulty are well overcome, and the public opinion problems caused by the picture, the voice, the video and other unstructured data are solved; and early warning assessment is used, the association rules are updated online in real time by using the unique reinforcement learning method, and the reliability and timeliness of the early warning are ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of network public opinion early warning, in particular to a public opinion early warning method based on unstructured data. 【Background technique】 [0002] Internet public opinion refers to the highly influential and tendentious speeches and opinions held by the public on certain hot spots and focus issues in real life through the Internet. Improper Internet public opinion will endanger the public safety of the society, so timely early warning of Internet public opinion becomes extremely important. [0003] Previous Internet public opinion early warnings mainly used text analysis methods to analyze structured data to obtain the public opinion security level of the article / news and whether early warning was required. This technology can solve part of the online public opinion crisis at the moment, but some online public opinion hazards that are spread in pictures, voices, and videos in the current social n...
