XTRACTIS FOR homeland security
Temporal Identification of Criminal Profiles & Action Phases from Communications Metadata during Surveillance Investigations
Benchmark vs. Logistic Regression, Random Forests, Boosted Trees & Neural Networks
Design an AI-based decision system that:
- Accuately identifies risky behavior linked to criminal activities by analyzing communication metadata from surveillance investigations, without accessing the content of telephone calls.
- Rationally predicts dangerous Homeland Security situations.

Goals & benefits
Identify specific metadata characterizing different criminal activities and enhance expert knowledge by helping intelligence specialists understand the causal relationships between the communication profiles and the roles inside criminal organizations.
Help intelligence services detect attacks as early as possible and understand the underlying strategy of the criminals in order to consider measures to thwart future attacks.
Avoid a large number of false alarms.
XTRACTIS-INDUCED DECISION SYSTEM
- The top-model is a decision system composed of 12 gradual rules without chaining, aggregated into 10 disjonctive fuzzy rules.
- Each rule uses only some of the 24 variables that XTRACTIS identified as significant (out of the 321 potential predictors characterizing the communications metadata).
- Only a few rules are triggered at a time to compute the decision.
It has a good Real Performance for all the 6 External Test scenarios.
It computes real-time predictions up to 70,000 decisions/second, offline or online (API).
