Enhanced Heartbeat Graph for emerging event detection on Twitter using time series networks.
Expert Systems with Applications(2019)
摘要
•Burstiness based approaches ignore minor details important for event detection.•Proposed approach captures divergence in a Twitter stream to detect events.•Divergence is captured through topological and sequential relations using graphs.•Proposed approach uses three novel features to detect emerging events.•The proposed approach is efficient and outperforms state-of-the-art methods.
