  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Kamath, Uday; De Jong, Kenneth; Shehu, Amarda (Public Library of Science, 2014-07-17)
    Background Many open problems in bioinformatics involve elucidating underlying functional signals in biological sequences. DNA sequences, in particular, are characterized by rich architectures in which functional signals ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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, ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Eranki, Avinash; Cortes, Nelson; Ferenček3, Zrinka Gregurić; Siddhartha, Sikdar (Journal of Visualized Experiments, 2013-09)
    Ultrasound is an attractive modality for imaging muscle and tendon motion during dynamic tasks and can provide a complementary methodological approach for biomechanical studies in a clinical or laboratory setting. Towards ...
