| description | The invention provides an analysis method for deducing social events by using a data model. Comprising the following steps of 1, obtaining big data, collecting information of emergencies and automatically crawling online comment data through a web crawler, 2, preprocessing the online comment data and storing the online comment data in a database, 3, collecting information features and constructing a key spatio-temporal feature model of the emergencies, and 4, establishing a key spatio-temporal feature model of the emergencies according to the key spatio-temporal feature model of the emergencies. And 4, carrying out social emotion classification on the emergencies. According to the analysis method for deducing the social event by using the data model, the problem that the public opinion guidance of the time cannot be accurately known at the first time due to the burst type of the hot event, and a result which is completely irrelevant to the social event can be possibly obtained is solved.
