Social Media Analytics

In our recent work on user profiling in social media we have looked at the role of conversational structures plays in identifying personality (Appling, Briscoe, Hayes, & Mappus, 2013). Current work applying this knowledge has shown a mean precision improvement of 20% on predicting dimensions of personality when conversational structure is combined with content analysis.

PCA Analysis of Credibility Factor Dimensions
Other work has focused on the identifying linguistic cues to deception, using these as features in machine learning models (with mean precision scores of 91%).

Additionally, we are conducting research on the differences in automated measurement methods of sentiment (opinions) and how they compare to traditional polling methods, especially during times of civilian uprest.

Price Targeting for Optimal Adoption

Also we have conducted research into using social network information to target individuals in terms of optimizing profit through pricing strategies .

Insider Trading Social Network Analysis

Chip Mappus has been working on determining insider-trading strategies through the use of network analysis of companies’ insider rosters.

Insider Threat Detection

We have also modeled behavior to understand and detect when people are acting maliciously.
