This paper highlights the common issues and trends presented from the panel discussion. The different panelists highlighted methods of filtering methods, data aggregation, and the importance of context for realtime analytics. Using the panelist perspectives, the review organizes the common issues and themes as well areas of future analysis of content and context enrichment from information fusion.

In the latter case, contextual reasoning involves inferring desired information (values of “problem variables”) on the basis of other available information (“context variables”). Relevant contexts are often not self-evident, but must be discovered or selected as a means to problem-solving. Therefore, context exploitation involves (a) predicting the value of contextual information to meet information needs; (b) selecting information types and sources expected to provide information useful in meeting those needs; (c) determining the relevance and quality of acquired information; and (d) applying selected information to a problem at hand. Fusion of contextual information can improve the quality of inferences, but involves concerns about the quality of the contextual information. The availability and quality of predictive models dictate the ways in which contextual information can be used. Many applications are benefitted by inference systems that adaptively discover and exploit context and refine such models to meet evolving information states and information needs.

However, training and expertise in crisis response varies widely among practitioners, and there has been considerable controversy about the value of widely disseminated mental health crisis intervention protocols that include "debriefing" as an essential feature. This article gives an overview of the developmental process, guiding principles, and core actions of the Psychological First Aid Field Operations Guide (PFA Guide), which provides guidance for practitioners in responding to immediate mental health needs of children, adults, and families who have recently experienced a disaster or terrorist event. Issues in training, provider self-care, and evaluation research are also presented. The PFA Guide presents approaches thought to be most consistently supported by current research and practice so that they can be taught, used, and evaluated in field settings. Although we expect further refinement as more systematic research becomes available, the PFA Guide represents a sustained collaborative effort to define current evidence-informed best practices that can be utilized now by practitioners involved in disaster mental health responses.

Responsive actions are decomposed into measurement, inference, planning and control components) and are predicted as a function of the estimated capability, opportunity and intent of given agents to perform such component actions. This representational scheme enables the generation of process models for predicting capabilities development (Technical Intelligence

The JDL data fusion model and its variants are seen as a method to partition a problem space in a way that tends to support different types of solutions. The layered view of fusion presented in these models is a rough engineering-based representation of a domain that has been addressed in analytically- and empirically-based models developed over centuries by philosophers and cognitive scientists. These ontological and cognitive models involve distinctions that are not all necessarily hierarchical or sequential. A hierarchical partitioning - while often convenient in characterizing fusion problems - should not be an impediment to fusion solutions that span the levels. A more flexible and comprehensive partitioning scheme is suggested.

While everybody recognizes the importance of considering context in inferencing, designers of information fusion processes only recently have begun to incorporate context explicitly into fusion processes. Effective context exploitation requires a clear understanding of what context is, how to represent it in a formal way, and how to use it for particular information fusion applications. Although these problems are similar to the ones discussed by researchers in many other fields, consideration of context in designing information fusion systems also poses additional challenges such as understanding the relationships between situations and context, utilizing context for understanding and fusion of natural language dat...

We model this in terms of “context variables” which a (human or automated) decision system seeks, discovers and evaluates as a means to infer or refine desired information (“problem variables”). An adaptive evidence-accrual inference method is presented, whereby context variables are selected on the basis of (a) their utility in refining explicit problem variables, (b) the probability of evaluating these variables to within a given accuracy, given candidate system actions (data collection, mining or processing), and (c) the cost of such actions. The JDL Data Fusion Model, extended to dual Resource Management functions, has been refined to accommodate adaptive decision, to include adaptive context exploitation. The interplay of Data Fusion and Resource Management (DF&RM) functionality in exploiting contextual information is developed by means of...

We suggest a general ontology of problem-solving processes and characterize several types of data acquisition/fusion problems in terms of this ontology. By relating data acquisition/fusion problem solution to a more general theory of problem-solving, the methodology framework will assist the information system planner or analyst to • Find analogies in other domains to problems or subproblems of interest • Learn from experience in solving analogous problems • Leverage techniques and metrics used in solving analogous problems.

This technology is being incorporated into a prototype system for assessing and predicting activity in threat-related Social Networks. Classical multi-source, multi-target calibration/registration / state estimation methods are applied to the joint characterization of human information sources and their reported target/ situation state estimates/ A Structural Equation Model framework is used to integrate a source agent's measurement, inference, planning and control processes with “our” independent observations of agent, targets and situations. Human behavior models are embedded in this framework to characterize both human sources and human targets.

The planner will provide the adaptivity to dynamic and uncertain mission situations by assembling response plans in a hierarchical fashion. Long-term plans are sketched in general terms using default estimates of performance. Specific plans are assembled incrementally as needed, by activating lower-level planners. The planner is an element of a conceptual threat assessment/response (TAR) system. The TAR system concept is being developed as an independent research effort in response to a generic need to develop technology for integrating system assessment, planning, and control functions in tactical aircraft.<<ETX>>
