Abstract

The invention provides a public opinion early warning method and device based on a knowledge graph, and the method comprises the steps: obtaining a public opinion event of a target object and an initial knowledge graph; constructing a knowledge graph according to the public opinion event and the initial knowledge graph to obtain a target knowledge graph; obtaining a public opinion analysis request, and analyzing a matched public opinion event in the target knowledge graph to obtain a public opinion analysis result; according to the public opinion analysis result and the target knowledge graph,sending a public opinion early warning notification to a user terminal of a corresponding person. According to the method, the target knowledge graph is constructed through the public opinion event of the target object and the initial knowledge graph, and the matched public opinion event in the target knowledge graph is analyzed, so that the public opinion analysis result is deeper and more specific, the product problem can be more accurately and effectively positioned, and an early warning notification can be sent to the corresponding personnel, so that the corresponding personnel can followup in time.

Description

Technical field [0001] This application relates to the technical field of public opinion monitoring, specifically, to a public opinion early warning method and device based on a knowledge graph. Background technique [0002] Public opinion is the "state of public opinion", which mainly refers to the attitude of the people as the main body towards a certain object around the occurrence, development and change of intermediary social events in a certain social space. [0003] For most companies, the public opinion of the company's products affects the quality, sales and development of the company's products, etc. Therefore, it is very necessary to monitor the public opinion of the company's products. [0004] At present, public opinion monitoring of enterprise products is mainly based on simple analysis of online public opinion data and events. In this case, the analysis results obtained are often too simple, and it is difficult to accurately and effectively discover the real problems o...
