Retrospective event detection is an important task for discovering previously unidenti\ufb01ed events in a text stream. In this paper, we propose two fast centroid-aware event detection models based on a novel text stream representation \u2013 Burst Information Networks (BINets) for addressing the challenge, following the D2N2K (Data-to-Network-to-Knowledge) paradigm. The BINets are time-aware, ef\ufb01cient and can be easily analyzed for identifying key information (centroids). These advantages allow the BINet-based approaches to achieve the state-of-the-art performance on multiple datasets, demonstrating the ef\ufb01cacy of BINets for the task of event detection.<\/p>\n","protected":false},"excerpt":{"rendered":"
