Abstract

The invention provides an emergency multi-dimension analysis system based on social media, which is characterized by comprising an emotion analysis module, a topic classification module, an emergencyfinding module and a public opinion analysis module; the emotion analysis module is used for completing the emotion classification of text content. The topic classification module is used for completing the topic classification of the text content. The emergency finding module is used for completing the automatic extraction of the emergencies on the social media in a certain time period, and finally, the detected emergencies are presented in a word-bag manner, and the data foundation is provided for the public opinion analysis module. The public opinion analysis module achieves the automatic and multi-dimension analysis for the emergencies: the emergencies are completely analyzed and understood from the aspects of emotion, topic, crowd, space and the like.

Description

technical field [0001] The invention relates to an analysis system, in particular to a social media-based multi-dimensional analysis system for emergencies.
