POLIS: Pattern of Life Integrated System

This proposal describes a technology system called POLIS (Pattern of Life Integrated System), which combines research in stochastic graph matching with logic-based semantic graph techniques to provide intelligence analysts superior capabilities for performing activity-based intelligence specifically pattern of life calculation in near-real time. Combining math-based with logic-based techniques provides an advanced technology platform that intelligence analysts can use for manipulation of large-scale graphs, both in terms of their categorical metadata as well as statistical characteristics surrounding weighted relationships, trust, and provenance/pedigree. The computational outputs of performing various types of graph matching/aligning are driven to a user-friendly semantic wiki, where humans can easily interact with the data and effectively represent and track POL activities of various types. The intuitive wiki platform allows users to deal with basic entity types such as persons, organizations, times, locations, etc., thereby shielding them from the complex graph heuristics being performed under the hood. POLIS is built upon a MapReduce framework making it highly scalable for multiple users and applications running at cloud-scale.
