Topic Detection and Tracking

With the rapid development of the Internet and social media technology, both the scale of information and the speed at which it is shared and disseminated are increasing. While people enjoy the convenience brought by the rich information on the Internet, they also suffer from the challenges brought by the information explosion. First, it is difficult for people to extract the information they need quickly and accurately from the vast amount of information on the Internet. Second, the information related to a given topic is often scattered across different periods of time and locations, which makes it more difficult for people to gain a comprehensive grasp of a topic. Faced with this massive, multisource, and diverse information, there is an urgent need for a technology that can effectively organize and aggregate information based on topics or events and that can also efficiently detect and track topics that users are interested in.
