|
 | Architecture frameworks have become a popular means of coping with the complexity of today's enterprises. They support the specification of architectures by providing a method for designing and describing them. An architecture framework typically defines a common terminology, a set of views focusing on particular aspects of the architecture, a set of architecture types with varying levels of detail, and a methodology for the development and maintenance of an architecture ... |

|
| Battle Management Language (BML) is a formal language for military communication, i.e., exchanging orders and reports. Orders and reports refer to geo-information. In particular, orders use overlays to connect geo-information to task assignments. The problem studied by this project is how to formalize geo-information and overlays, and to connect this formalized information to BML orders and reports such that a system can process them coherently and operate on the processed ... |

|
| In this paper we present a combined approach to the automatic (pre-) analysis of intelligence reports. The combination encompasses information extraction (IE) and information enrichment by means of ontologies. The combined approach proves to yield superior results compared to standalone IE. For our work we mainly use open standards and open source software. For the purpose of IE, for instance, we use the GATE system, whereas our ontology work is ... |

|
| Command, Control, and Information Systems (C2ISs) are complex software products that must conform to agreed standards in order to be interoperable in joint and combined operations. Due to the complexity of information exchange between heterogeneous C2ISs, thorough testing is indispensable to gain confidence that these standards are implemented correctly and semantic interoperability is indeed achieved. Testing can be performed in many different ways and by various means. For the Multilateral ... |

|
| For a sensible application of Augmented Reality (AR) and Virtual Environments (VE) it is necessary to include basic human information processing resources and characteristics. Because there is no fully functional model of human perceptual, cognitive, and motor behavior, this requires empirical analyses. Moreover, these analyses are often based on subjective ratings rather than objective measures. With regard to perception as the basic sensation of synthetic environments, each modality should be ... |

|
| The current transformation processes aim at robustly networked forces in order to enable them to execute network-centric operations. Obviously, this will provide the forces headquarters with a huge amount of data and information that has to be processed to deduce an appropriate picture of the respective battlespace and evolving threats in a timely and most reliable manner. Some of the data will not be relevant at all, but some other ... |

|
| The authors present the concept of a network resource manager for tactical military computer networks based on the Internet Protocol Version 6. This manager is a security gateway with a number of enhanced functionalities. In particular, the gateway supports priority based services and efficient bandwidth management. Furthermore, it is capable to handle secure multicast communication. |

|
| Current Military Message Handling Systems (MMHS) are based on the X.400 standard of the International Standardization Organization. Recent examinations have shown that the Simple Mail Transfer Protocol (SMTP) can satisfy most requirements for MMHS. For the only relevant requirement not satisfied, we have developed a solution. This paper describes the solution and an experimental implementation. Additionally, the results from a series of tests on a tactical narrow bandwidth testbed are ... |

|
| In many engineering applications, including surveillance, guidance, or navigation, single stand-alone sensors or sensor networks are used for collecting information on time varying quantities of interest, such as kinematical characteristics and measured attributes of moving or stationary objects of interest (e.g. maneuvering air targets, ground moving vehicles, or stationary movers such as a rotating antennas). More strictly speaking, in these applications the state vectors of stochastically moving objects are to ... |

|
| A super-resolution high frequency (HF) direction finding (DF) system has been used to measure the temporal characteristics of mid-latitude ionospheric irregularities. By analysis of the log power spectrum of the temporal profiles they are classified into six classes: (1) traveling wave packets (TWPs), (2) wave trains (WTs), (3) large-scale traveling disturbances at the terminator (TLSTIDs), (4) interference of different waves (IDW), (5) chaos and (6) quiet state. Their occurrence is ... |

|
| New sensors, communication infrastructure, and information systems will make plenty of information about actual mission scenarios available. Innovative concepts like Network Centric Warfare (NCW) describe the consequent availability of this information for each command level at any time, at any place. But the huge amount of information may also lead to information overload for the human commander: Relevant information may be overseen. This might results into building a wrong mental ... |

| Towards a Higher Level of Interoperability: Ontology Components for Command and Control Systems |

| Authors:
Ulrich Schade; FGAN-FKIE WACHTBERG (GERMANY)
|
| The paper at hand argues that ontological components should be incorporated into command and control systems in order to increase their level of interoperability. The term ontology is explained, and capabilities of ontological components are illustrated by example. The example's lessons are generalized and exploited for an advanced approach. |

| A Base Component for Network-Based Service-Oriented C4ISR Systems |

|
| Network Centric Warfare poses new challenges to C4ISR systems: future systems must provide access to a homogenous information and service space for a broad spectrum of users whose computation and communication resources vary and whose location may change frequently. We propose a design schema for network-based, service-oriented C4ISR systems and present a base component upon which such systems can be built on. From a user's point of view, the base ... |

|
| Due to the new military operations other than war, the extent of the natural language parts in formalized military messages increases. In order to guarantee further automatic interoperability between different C4ISR systems three problems must be solved. First, the natural language text must be automatically transformed into a formal structure, which represents the meaning of the text. Second, the formal structure must be exchanged between the different C4ISR systems. And ... |

|
| Interoperability of command and control information systems gains an ever-increasing importance. The aim of the Multilateral Interoperability Programme (MIP) is to achieve international interoperability in order to support land component commanders in joint and combined operations. For that purpose, MIP defines the Command and Control Information Exchange Data Model (C2IEDM) and the Data Exchange Mechanism (DEM). However, when implementing the MIP Solution, it is not sufficient to simply add new ... |

|
| Features are a means of statistical pattern recognition that ATR algorithms use to discriminate ground targets from the surrounding clutter background and, subsequently, to sort potential targets into one of several target classes (including the non-target case). Problems for ATR arise from the specular nature of radar imagery because small changes to the configuration of targets can result in significant changes to the resulting target signature [3][4]. This adds to ... |

| The Benefit of Ontologies for Interoperability of CCIS. (Easy, Quick and Cheap Solutions are Impossible, if Semantics of CCIS are Affected.) |

| Authors:
Michael A. Wunder; FGAN-FKIE WACHTBERG (GERMANY)
|
 | In spite of their efforts, no one has yet succeeded in making Command and Control Information Systems (CCIS) semantically interoperable. The harmonization of information systems is extremely expensive and, in many cases, it has not brought the expected improvements. Another approach to the problem of semantic harmonization may be necessary. According to the author, information exchange can be supported by knowledge-based linguistic algorithms that analyze incoming information and convert it ... |
