| Abstract: | This paper describes a micro-blog hot topics detecting system. System managers can quickly find the micro-blog hot events that are taking place or has occurred. The system uses a combination of calling micro-blog API interface and improving crawler program to get web data; Due to the huge amount of network data, in order to improve efficiency, the System uses web cleaning technology; focuses on the method of the topic activity model, the System can quickly find the hot topic by the time coordinate, and improve efficiency of the hot topics detection and greatly reduce the time complexity of the hot topics detection. |
