We discuss cognitive topics related to an Intelligence Analyst's Geospatial and Ontological Assistant (IAGOA) under development that associates an analyst's understanding of an agent's activities with the geospatial features of the area where they take place. IAGOA uses linguistic resources from the lexical database FrameNet, based on Fillmore's frame semantics (not related to Minsky's frames), and...
The concept of situation is central to the decision making processes of both human and software agents. The recognition of situation facilitates decision processes that ultimately result in action selection. Cognitive agent architectures that incorporate the concept of situation provide the opportunity for more sophisticated representations of human behavior and for more sophisticated decision support...
In a disaster, accurate information is a resource that is often in short supply. The combination of rapidly unfolding events and the frequent loss of communication infrastructure including mobile phones, landlines, Internet and television broadcast make it difficult to gain situational awareness. And while there is obvious value in aggregating information for centralized emergency authorities, disasters...
`Switch and Deliver' is a research project directed to design and develop tools/techniques and procedures to aid operators in handling Multiple Operator Multiple UAV (unmanned aerial vehicles) environments. It aims to identify what information and which tools and layouts will decrease switch-costs and improve overall mission performance. Nevertheless, most tools/techniques can be generalized to any...
We investigated the effects of a decision aid designed to support the development of effective long term strategies when seeking to influence a complex adaptive system. The experiment compared a test condition with feedforward support (i.e., outcome projection) against a baseline condition both in terms of cognitive processing and goal attainment (i.e., strategy efficiency). Results show that the...
Situation management requires means for describing various things, both situation states and developments. For this reason we turn to algebraic systems. We define time as a system, as well as systems that are time-dependent. We consider the application of the DST dialogue system as one possible way to reliably represent descriptions in the form of formulas.
The prevalence of surveillance and information collection technologies provides decision-makers with greater volume and complexity of information to monitor and on which to base decisions than ever before. In this ever increasing dynamic and information rich environment, the role for decision support systems (DSS) to augment cognition and situation awareness (SA) is becoming crucial. However, unless...
In this paper we present a distributed event driven middleware architecture for situational awareness and intelligent decision making for command and control of geographically distributed networked battlefield agents. We tackle the important and challenging issues of distributed agents scheduling, synchronization, load balancing, and terrain database distribution/management/allocation in a distributed...
Humans make decisions on the basis of their situation awareness and it is well-known that insufficient situation awareness leads to incorrect decisions. The challenge of an advanced surveillance system for supporting situation awareness of a human decision maker is therefore to detect and assess complex situations that evolve over time. In this article, we present a conceptual framework for automatic...
The Undersea Warfare Decision Support System (USW-DSS) will enhance Naval Fleet capabilities by providing a “Common Tactical Picture” between platforms. However, USW-DSS encapsulates a number of mission-critical tasks across many contexts, necessitating solutions to improve multi-tasking and context switching. As part of a Small Business Innovation Research (SBIR) project, we have formulated an approach...
The application of techniques from artificial intelligence, human decision-making processes, optimization, and learning methodologies have led to significant development in the field of cognitive radios. A cognitive radio improves on a traditional radio by incorporating situational awareness, learning, and decision-making to meet the application goals and adapt to the current operating environment...
In a tactical battlefield, ground- and air- based robotic assets can be useful, but there is currently no one role to coordinate the use of multiple robots in the U.S. Army. The current work outlines and models the duties of a robotics operator manager (ROM), which could serve this role, using a theory of dynamic decision-making, instance-based learning (IBL). A model of the ROM is created that is...
This paper describes computational models of situated work in complex, heterogeneous dynamic systems that include humans, physical systems, computer agents and regulatory requirements, using aviation as the domain being examined but highlighting modeling principles generalizable to other domains. Work is defined formally here as purposeful activity acting on, and responding to, the environment as...
The following topics are dealt with: decision support; learning; threat situation modeling; human situational behavior; human performance; and agent-based situation awareness.
Smart environment is defined here as a number of devices that can share information and services independently of their physical location. Smart environments based on ubiquitous computing open new possibilities to various aspects of human activities. The paper proposes an approach to emergency situation response that benefits of the ubiquitous computing. The approach is based on utilizing role profiles...
Intelligent infrastructure is an architecture that enables generation of immediate, accurate and relevant information about the state of any type of infrastructural asset and converts this information to timely and reliable decision aids. The study presented in this paper identifies the scope of railway intelligent infrastructure system via a mixed contextual and sequential approach. The output from...
This paper investigates a display manipulation designed to support movement tasks where the location of a threat is uncertain and dynamic. The problem is analogous to that of a naval transportation task, where a ship has to move from one port to another under threat from several enemies of which only the initial positions are known. The display manipulation visualizes a time-dependent constraint on...
Ubiquitous computing technologies have been developed fast and various decision support systems were proposed. Consecutively, in recently, people are working on an implicit service agent of mobile phone to make people to be provided useful services without paying attentions. However, when people want to buy some products or to go somewhere, people are still going to use Internet to get preference...
Modern warfare is focusing on expanding the extent of Network Centric Warfare (NCW) and Networked Control Systems (NCSs). The Finnish Defence Forces (FDF) is, among other armies, trying to find a reliable solution for the architectural and technical design of a new operational information network. This paper focuses on discussing the possibilities of creating new Service Oriented Architecture (SOA)...
