The THOR Framework builds on Neon open source middleware platform for big data access and visualization developed for the DARPA XDATA and Memex programs. Neon, already interfaces with most standard data formats, which is extended to process streams of unstructured text and to accept data from an open-ended set of LTDE Web services. The framework also leverage USC ISI’s open source Domainspecific Insight Graph (DIG) technology, developed over the course of multiple programs including Memex, to capture the critical elements of information in a Knowledge Graph that support large-scale entity resolution, provenance reasoning, and network analysis. The team coordinate the design and implementation of the interfaces between the Language Technology Development Environment (LTDE) and LORELEI Run-time Framework(LRTF) though the implementation of Continuous Delivery techniques and tools.
The approach is successfully employees to coordinate multiple contractors on DARPA research efforts (e.g., DEFT, XDATA, Memex, VMR) as well as advanced software development activities for the Intelligence Community. Continuous Delivery not only simpliies API development but also ensure compliance with the agreed-upon interfaces. The THOR team leverages its portfolio of open source software to assemble THOR visual prototype demonstrations in Phase 1 and further leverage its humanitarian and disaster relief subject matter expertise to iteratively refine the design—an accelerated development approach that guarantees usability and performance in operational environments.
