Open-World Social Event Classification

With the rapid development of the Internet and multimedia technology, popular events on social media can quickly spread globally through user interactions such as forwarding and commenting. Open World Social Event Classification (OWSEC) aims to classify multimodal social media posts, with its test set containing new categories that did not appear in the training set. This task not only expands the application boundaries of natural language processing but also enhances the ability to recognize unknown events, making it of significant research and application value.
