Theft detection via adaptive lexical similarity analysis of social media data streams

摘要

A system and computer program product to detect an event include 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 a lexical graph generation algorithm to the set of social media data streams to obtain lexical graphs, and performing similarity analysis on the lexical graphs based on candidate lexical graphs related to the event to generate matching data. Investigating the event is based on the matching data.
