 | Our technique for selecting foreign-language technical terms for human-use glossaries and automatic processor lexicons offers a customized solution based on sound principles that has resulted in an effectiveness breakthrough for the Army. Prepared in support of a single Joint Task Force (JTF), its principle-based underpinnings justify its use in similar applications for various JTFs involved in strategic operations. Language induces expectations from its community of use that can be exploited ... |

|
| Building on recent interest in distributed logic programming, we take a model-theoretic approach to analyzing confluence of asynchronous distributed programs. We begin with a model-theoretic semantics for Dedalus and develop the concept of ultimate models to capture the non-deterministic eventual outcomes of distributed programs. After demonstrating the undecidability of checking confluence for Dedalus programs, we look for restricted sub-languages that guarantee confluence while providing adequate expressivity. We observe that a ... |

| Background: The Millennium Cohort Study is a longitudinal cohort study designed in the late 1990s to evaluate how military service may affect long-term health. The purpose of this investigation was to examine characteristics of Millennium Cohort Study participants who responded to the open-ended question, and to identify and investigate the most commonly reported areas of concern. Methods: Participants who responded during the 2001-2003 and 2004-2006 questionnaire cycles were included in ... |

| Objects model the world, and state is fundamental to a faithful modeling. Engineers use state machines to understand and reason about state transitions, but programming languages provide little support for building software based on state abstractions. We propose Plaid, a language in which objects are modeled not just in terms of classes, but in terms of changing abstract states. Each state may have its own representation as well as methods ... |

| This project addressed the relation extraction problem in resource-poor domains. This problem is one of extracting information regarding relationships between entities, which involves extracting text spans specifying the entities involved and classifying the relationship between these entities into one of several pre-defined classes. The primary technique for solving such problems is machine learning. An obstacle to the widespread application of machine-learning methods is the necessity for relatively large amounts of ... |

| The DoD defines delegation of authority as the action by which a commander assigns part of his authority commensurate with the assigned task to a subordinate commander. While ultimate responsibility cannot be relinquished, delegation of authority carries with it the imposition of a measure of responsibility, the extent of which must be clearly stated. Similarly, access to enterprise services and information can be controlled through delegation of credentials by an ... |

| Written information for military purposes is available in abundance. Documents are written in many languages. The question is how we can automate the content extraction of these documents. One possible approach is based on shallow parsing (information extraction) with application specific combination of analysis results. One example of this, the ZENON research system, does a partial content analysis of some English, Dari, and Tajik texts. Another principal approach for content ... |

| Within the Department of Defense (DoD), delegation of authority is the act by which a commander transfers part of his authority to a subordinate commander in order to complete an assigned task or carry out additional duties. Delegation is often limited to specific tasks or for specific time periods and is commonly governed by policies that specify what may be delegated, to whom it may be delegated, and under what ... |

| Increased focus on multi-functional and multi-national operations brings new requirements to military command and control, in addition to other capability requirements. Parallel but separate from this development, interoperability has been of major concern within Modeling and Simulation (M&S) for years, especially in connection with standards for distributed simulations, e.g. High Level Architecture (HLA). Both areas share a need to create configurations of systems where elements of information exchanged are interpreted ... |

| Means to build fault-tolerant services have been at hand for some time. Defense against attacks remains a difficult problem, though. The problem becomes ever more urgent with the increasing use of networked computing systems in our society's critical infrastructures and in future-generation military systems (such as GIG and JBI). The objective of this AFOSR-funded effort was to bridge the gap from fault-tolerance to attack-tolerance by exploring two threads. The first ... |

|
| One of the central problems in spatial language understanding is the polysemy and the vagueness of spatial terms, which cannot be resolved by lexical knowledge alone. We address this issue by developing a representation framework for functional interactions between objects and agents. We use this framework with a constraint solver to resolve and recover the meanings of spatial descriptions for object placement tasks. We describe our approach in a virtual ... |

The underlying mechanism of typical search methods is based on keyword matching, which has demonstrated poor performance compared to highly technical requirements documents found within the field of acquisitions. Instead of matching keywords, an IR method that understands the meaning of the words in a query is ... |

| As part of its type-safety regime, the Java semantics require precise exceptions at runtime when programs attempt out-of-bound array accesses. This paper describes a Java implementation that utilizes a multiphase approach to identifying safe array accesses. This approach reduces runtime overhead by spreading the out-of-bounds checking effort across three phases of compilation and execution production of mobile code from source code, JIT compilation in the virtual machine and application code ... |

| Data fusion systems are being increasingly used to support military planning, decision making, and command and control functions in general. Typically, these systems are designed around the current capabilities of particular data collectors (e.g., sensors) and available processing algorithms.

| The goal of the Department of Defense Net-Centric Data Strategy is to improve data sharing throughout the DoD. Data sharing is a critical element of interoperability in the emerging system-of-systems. Achieving interoperability requires the elimination of two types of data heterogeneity: differences of syntax and differences of semantics. This paper builds a path toward semantic uniformity through application of a disciplined approach to ontology. An ontology is a consensus framework ... |

| We present an authorization logic DTL(o) that explicitly relativizes reasoning to beliefs of principals. The logic assumes that principals are conceited in their beliefs. We describe the natural deduction system, sequent calculus, Hilbert-style axiomatization, and Kripke semantics of the logic. We prove several meta-theoretic results including cut-elimination, and soundness and completeness for the Kripke semantics. Translations from several other authorization logics into DTL(o), as well as formal connections between DTL(o) ... |

| Over the last five to seven years the use of chat in military contexts has expanded quite significantly, in some cases becoming a primary means of communicating time-sensitive data to decision makers and operators. For example, during humanitarian operations with Joint Task Force-Katrina, chat was used extensively to plan, task, and coordinate predeployment and ongoing operations. The informal nature of chat communications allows the relay of far more information than ... |
