Human-aided multi-sensor fusion
This paper discusses some fundamental requirements for a human-aided multi-sensor fusion system, and proposes an approach that implements such a system. This approach involves integration of the probabilistic argumentation system and the structural evidential argumentation system, which both are variants of the Dempster-Shafer belief function theory.

Supporting the Pattern Development Cycle in Intelligence Gathering
This paper discusses the cycle through a use case of the Link Analysis Workbench (LAW), a tool for discovering and analyzing situations of interest in large relational data sets.

Designing a System for Structured Assessment of Compliance Risk
A formal reasoning technique known as structured argumentation has been explored by the IRS LMSB Research to improve compliance risk assessment. The IRS together with SRI International evaluated the use of structured argumentation using SEAS technology, towards enabling a more systematic and innovative approach towards assessing complex compliance issues.

Capturing Analytic Thought
We are developing a new methodology that retains the ease of use, the familiarity, and (some of) the free-form nature of informal methods, while benefiting from the rigor, structure, and potential for automation characteristic of formal methods.

Structured Argumentation for Analysis
We are developing a new methodology that retains the ease-of-use, familiarity, and (some of) the free-form nature of informal methods, while benefiting from the rigor, structure, and potential for automation characteristic of formal methods.

Multiple-Target Tracking in Dense, Noisy Environments: A Probabilistic Mapping Perspective
A new approach is taken to address the various aspects of the multiple-target tracking (MTT) problem in dense and noisy environments.

Ontology Construction Toolkit
The goal of this project was to enable knowledge engineers to construct knowledge bases (KBs) faster. To achieve this goal, we investigated two techniques: knowledge reuse and axiom templates. The results were demonstrated by developing a question-answering system for the crisis management challenge problem (CMCP).

Evidential Reasoning with Gister-CL: A Manual
This document is designed to serve as a self-contained introduction to evidential reasoning and Gister-CL. Evidential reasoning is a collection of techniques for automated reasoning from evidence; Gister-CL is an application independent implementation of these techniques.

A Generic Knowledge-Base Browser and Editor
The GKB Editor is a generic editor and browser of knowledge bases (KBs) and ontologies – generic in the sense that it is portable across several frame knowledge representation systems (FRSs).

Planning and Reacting in Uncertain and Dynamic Environments
The CYPRESS system is a domain-independent framework for defining persistent agents with this full range of behavior. It has been used for several demanding applications, including military operations, real-time tracking, and fault diagnosis.

Industrial Project Monitoring with Evidential Reasoning
The system identifies problems and developments that might lead to deviations from planned project outcomes and does so at such an early stage that effective corrective action can still be taken.
