Event Detection and Tracking in Social Streams
نویسندگان
چکیده
Events and stories can be characterized by a set of descriptive, collocated keywords. Intuitively, documents describing the same event will contain similar sets of keywords, and the graph of keywords for a document collection will contain clusters individual events. In this paper we build a network of keywords based on their co-occurrence in documents. We propose and develop a new event detection algorithm which creates a keyword graph and uses community detection methods analogous to those used for social network analysis to discover and describe events. Constellations of keywords describing an event may be used to find related articles. We also use the proposed algorithm to analyze events and track stories in social streams.

Event Detection in Social Media Data
Recent research has shown that a considerable fraction of social media streams are about “events”. Collectively, events serve as a succinct summary of social media streams. Individually, event and its sub-events, reveal the evolution of certain social phenomena over time. In addition, analyzing relationships between events and people’s responses to the events provides rich information on the ma...
متن کاملEvent Evolution Tracking from Streaming Social Posts
Online social post streams such as Twitter timelines and forum discussions have emerged as important channels for information dissemination. They are noisy, informal, and surge quickly. Real life events, which may happen and evolve every minute, are perceived and circulated in post streams by social users. Intuitively, an event can be viewed as a dense cluster of posts with a life cycle sharing...
متن کاملEvent Detection in Social Streams
Social networks generate a large amount of text content over time because of continuous interaction between participants. The mining of such social streams is more challenging than traditional text streams, because of the presence of both text content and implicit network structure within the stream. The problem of event detection is also closely related to clustering, because the events can on...
متن کاملWhat Is New in Our City? A Framework for Event Extraction Using Social Media Posts
Post streams from public social media platforms such as Instagram and Twitter have become precious but noisy data sources to discover what is happening around us. In this paper, we focus on the problem of detecting and presenting local events in real time using social media content. We propose a novel framework for real-time city event detection and extraction. The proposed framework first appl...
متن کاملTemporal and Information Flow Based Event Detection from Social Text Streams
Recently, social text streams (e.g., blogs, web forums, and emails) have become ubiquitous with the evolution of the web. In some sense, social text streams are sensors of the real world. Often, it is desirable to extract real world events from the social text streams. However, existing event detection research mainly focused only on the stream properties of social text streams but ignored the ...
