Paragon Science used a combination of network analysis, community detection, topic detection, sentiment analysis, and anomaly detection methods to find key influencers and viral topics in two recent Twitter data sets: one of 7.9 M tweets regarding ISIS, a second set consisting of more than 117 M tweets about the 2016 primary elections, and a third set of 7M tweets realted to Brexit.
Paragon Science's patented dynamic anomaly detection technology is based on methods drawn from dynamical systems and chaos theory. In particular, we can calculate finite-time Lyapunov exponents from any time-dependent data stream to find the clusters of entities that are behaving most chaotically compared to the rest of the data set. Because we do not have to specify normal vs. abnormal behavior in advance, no machine learning per se is required. In a robust fashion that is tolerant of missing or erroneous data, we can identify the "unknown unknowns" that can represent threats to be mitigate or opportunities to be seized. To date, our technique has been applied successfully to a broad range of industry verticals, including healthcare data (Advisory Board Company), web user behavior data (Vast), mobile phone data (Place IQ), vehicle pricing analytics (Digital Motorworks/CDK Global), online coupon data (RetailMeNot), email monitoring for patent law cases, and social media monitoring.
