Patent Images
1. A computer-implemented method of detecting an event, the method comprising:
- selecting a region and time frame of interest;
obtaining a set of social media data streams associated with the region and the time frame of interest;
applying, using a processor, a lexical graph generation algorithm to the set of social media data streams to obtain lexical graphs;
performing, using the processor, similarity analysis on the lexical graphs based on candidate lexical graphs related to the event to generate matching data; and
investigating the event based on the matching data.

Abstract
A method of detecting an event includes selecting a region and time frame of interest, obtaining a set of social media data streams associated with the region and the time frame of interest, and applying a lexical graph generation algorithm to the set of social media data streams to obtain lexical graphs. Performing similarity analysis on the lexical graphs is based on candidate lexical graphs related to the event to generate matching data, and investigating the event is based on the matching data.
