Online Story Discovery

Online story discovery focuses on automatically identifying and organizing related news articles or social media posts into coherent narratives from continuous streams of online data. Current research emphasizes unsupervised methods, employing techniques like density-based clustering, hierarchical embeddings, and contrastive learning to group information based on semantic similarity and temporal proximity, often incorporating natural language processing for improved accuracy. This field is significant for enabling efficient information consumption in the face of overwhelming online data volumes and offers potential applications in areas such as real-time news aggregation, social media analysis, and understanding the evolution of online narratives during significant events.
