  • An Application of Bayesian Networks to Antiterrorism Risk Management for Military Planners 
    Hudson, Linwood D.; Ware, Bryan S.; Laskey, Kathryn B.; Mahoney, Suzanne M. (2005-11-18)
    Recent events underscore the need for effective tools for managing the risks posed by terrorists. Assessing the threat of terrorist attack requires combining information from multiple disparate sources, most of ...
  • Bayesian ontologies in AI systems 
    Costa, Paulo C. G.; Laskey, Kathryn B.; AlGhamdi, Ghazi (2006-07-30)
    Ontologies have become ubiquitous in current-generation information systems. An ontology is an explicit, formal representation of the entities and relationships that can exist in a domain of application. Following a ...
  • Bayesian Semantics for the Semantic Web 
    Costa, Paulo C. G. (George Mason University, 2005-07-12)
    Uncertainty is ubiquitous. Any representation scheme intended to model real-world actions and processes must be able to cope with the effects of uncertain phenomena. A major shortcoming of existing Semantic Web technologies ...
  • Belief in Belief Functions: An Examination of Shafer's Canonical Examples 
    Laskey, Kathryn B. (North-Holland, 1989)
    In the canonical examples underlying Shafer-Dempster theory, beliefs over the hypotheses of interest are derived from a probability model for a set of auxiliary hypotheses. A belief function differs from a Bayesian probability ...
  • BML Enabled Information Exchange Framework in SES Ontology for C2 
    Lee, Hojun; Zeigler, Bernard (2009-10-05)
    This paper explores the Information Exchange Framework (IEF) concept of distributed data fusion sensor networks in Network-centric environment. It is used to build up integrative battlefield pictures through the Battle ...
  • Credibility Models for Multi-Source Fusion 
    Wright, Edward J.; Laskey, Kathryn B. (2006-07)
    This paper presents a technical approach for fusing information from diverse sources. Fusion requires appropriate weighting of information based on the quality of the source of the information. A credibility model ...
  • CWID 08 Demonstrates Rapid Evolutionary 
    Gunderson, C.R.; Raytheon, David Minton (2008)
    Coalition Warrior Interoperability Demonstration 2008 (CWID 08), Interoperability Trial (IT) #5.64 “Trusted Enterprise Service Bus” (T-ESB) demonstrates a potentially quantum improvement in the government procurement model ...
  • Detecting Threatening Behavior Using Bayesian Networks 
    AlGhamdi, Ghazi; Laskey, Kathryn B.; Wang, Xun; Barbará, Daniel; Shackelford, Thomas; Wright, Edward J.; Fitzgerald, Julie (2006-03-06)
    This paper presents an innovative use of human behavior models for detecting insider threats to information systems. While most work in information security concerns detecting and responding to intruders, violations of ...
  • DTB Project: A Behavioral Model for Detecting Insider Threats 
    Costa, Paulo C. G.; Laskey, Kathryn B.; AlGhamdi, Ghazi; Barbará, Daniel; Shackelford, Thomas; Mirza, Sepideh; Revankar, Mehul (MITRE Corporation, 2005-05)
    This paper describes the Detection of Threat Behavior (DTB) project, a joint effort being conducted by George Mason University (GMU) and Information Extraction and Transport, Inc. (IET). DTB uses novel approaches for ...
  • Evaluation of Geospatial Digital Support Products 
    Powell, Walter A.; Laskey, Kathryn Blackmond; Adelman, Leonard; Johnson, Ryan; Dorgan, Shiloh; Hieb, Micheal; Braswell, Kenneth; Powers, Michael (2010-04-20)
    Geospatial Reasoning has been an essential aspect of military planning since the invention of cartography. Geospatial Digital Support Products (GDSPs) are ubiquitous within current military forces as well as civil and ...
  • Evaluation of High Resolution Imagery and Elevation Data 
    Powell, Walter A.; Laskey, Kathryn Blackmond; Adelman, Leonard; Johnson, Ryan; Altenau, Michael; Goldstein, Andrew; Visone, Daniel; Braswell, Kenneth (Proceeding of 14th International Command and Control Research and Technology Symposium, 2009-06)
    How does the underlying data affect the ability of warfighters to derive useful information and make decisions? The Army Topographic Engineering Center (TEC) and GMU endeavor to shed light on this question with the third ...
  • An Investigation of Machine Learning Techniques for Use in Training Agents for Military Simulations 
    Hieb, Michael R.; Pullen, J. Mark (2006-05-05)
    Agents assist users with performing tasks in computer-based applications. The current practice of building an agent involves a developer programming it for each task it must perform, but agents constructed in this manner ...
  • Linear Referencing for Network Analysis of IED 
    Curtin, Kevin M. (2009-09-15)
    This paper outlines a motivation for associating IED events (and other significant physical and human geographic features) with the road network, describes the use of methods known as linear referencing in order to do so, ...
  • MEBN Logic: A Key Enabler for Network Centric Warfare 
    Costa, Paulo C. G.; Laskey, Kathryn B.; Takikawa, Masami; Pool, Michael; Fung, Francis; Wright, Edward J. (CCRP Publications, 2005-06)
    Among the lessons learned from recent conflicts stands the dramatic change in the very way wars are fought. There are no more clear-cut enemies or allies; rules of engagement have become increasingly fuzzy; guerrilla and ...
  • MEBN: A Logic for Open-World Probabilistic Reasoning 
    Laskey, Kathryn B. (2006-02-03)
    Uncertainty is a fundamental and irreducible aspect of our knowledge about the world. Probability is the most well-understood and widely applied logic for computational scientific reasoning under uncertainty. As theory and ...
  • Modeling Insider Behavior Using Multi-Entity Bayesian Networks 
    AlGhamdi, Ghazi; Laskey, Kathryn B.; Wright, Edward J.; Barbará, Daniel; Chang, K.C. (2006-03-06)
    This paper tackles a key aspect of the information security problem: modeling the behavior of insider threats. The specific problem addressed by this paper is the identification of malicious insider behavior in trusted ...
  • Multi-Entity Bayesian Networks without Multi-Tears 
    Costa, Paulo C. G.; Laskey, Kathryn B. (2006-01-27)
    An introduction is provided to Multi-Entity Bayesian Networks (MEBN), a logic system that integrates First Order Logic (FOL) with Bayesian probability theory. MEBN extends ordinary Bayesian networks to allow representation ...
  • Net-Centric Adapter for Legacy Systems 
    Thomas, Alan; Turner, Thomas; Soderlund, Scott (2008)
    The Net-Centric Adapter for Legacy Systems (NCALS) is a software technology that makes legacy system data and services available in near real-time to the Global Information Grid (GIG). The intent of NCALS is to lower the ...
  • Of Starships and Klingons: Bayesian Logic for the 23rd Century 
    Laskey, Kathryn B.; Costa, Paulo C. G. (AUAI Press, 2005-07)
