[Abstract]:With the development of information technology and the popularity of social media, ordinary users have completed the transition from information receiver to information producer. Everyone can share the information around them in real time, and they can also forward the content of their own interest. This has led to a rapid increase in the amount of data on social media. There are abundant records of the occurrence and development of social events in the massive data. How to effectively mine valuable information from these data has become an important problem in the field of information. In order to solve this problem, the event awareness and multi-modal event context generation based on social media are introduced. Event perception and multimodal event context generation based on social media aims at perceiving events and portraying the relationship of events by analyzing multimodal data such as text, time, image, comment, viewpoint, emotion and user interaction in social media. In order to achieve the summary of events. This paper discusses the description model, concept, development history, key technologies and challenges of event perception and multi-modal event context generation based on social media, as well as its wide range of applications. This paper reviews the research progress of social media analysis in event perception and event summary, and looks forward to its future development.
