On the Predictive Power of Web Intelligence and Social Media The Best Way to Predict the Future Is to tweet It

摘要

With more information becoming widely accessible and new content created every day on today's web, more are turning to harvesting such data and analyzing it to extract insights. But the relevance of such data to see beyond the present is not clear. We present efforts to predict future events based on web intelligence - data harvested from the web - with specific emphasis on social media data and on timed event mentions, thereby quantifying the predictive power of such data. We focus on predicting crowd actions such as large protests and coordinated acts of cyber activism - predicting their occurrence, specific timeframe, and location. Using natural language processing, statements about events are extracted from content collected from hundred of thousands of open content web sources. Attributes extracted include event type, entities involved and their role, sentiment and tone, and - most crucially - the reported timeframe for the occurrence of the event discussed - whether it be in the past, present, or future. Tweets (Twitter posts) that mention an event to occur reportedly in the future prove to be important predictors. These signals are enhanced by cross referencing with the fragility of the situation as inferred from more traditional media, allowing us to sift out the social media trends that fizzle out before materializing as crowds on the ground.
