Composable M&S web services for net-centric applications

Service-oriented architectures promise easier integration of functionality in the form of web services into operational systems than is the case with interface-driven system-oriented approaches. Although the Extensible Markup Language (XML) enables a new level of interoperability among heterogeneous systems, XML alone does not solve all interoperability problems users contend with when integrating services into operational systems. To manage the basic challenges of service interoperation, we developed the Levels of Conceptual Interoperability Model (LCIM) to enable a layered approach and gradual solution improvements. Furthermore, we developed methods of model-based data engineering (MBDE) for semantically consistent service integration as a first step. These methods have been applied in the U.S. in collaboration with industry resulting in proofs of concepts. The results are directly applicable in a net-centric and net-enabled environment

SOA4All, enabling the SOA revolution on a world wide scale

SOA4All will help to realize a world where billions of parties are exposing and consuming services via advanced Web technology. The outcome of the project will be a comprehensive framework and infrastructure that integrates four complimentary paradigm-shifting technical advances into a coherent and domain independent service delivery platform: Web principles and technology as the underlying infrastructure for the integration of services at a world wide scale; Web 2.0 as a means to structure human-machine cooperation in an efficient and cost effective manner; Semantic Web technology as a means to abstract from syntax to semantics as required for meaningful service discovery; and context management as a way to process in a machine understandable way user needs that facilitate the customization of existing services for the needs of users

Toward a service web: integrating the Semantic Web and service orientation

By a variety of metrics, the Semantic Web is doing very well. For example, the 2006 Gartner report included the “Corporate Semantic Web” as one of three key technology themes, and in 2007, Tim Berners-Lee briefed a hearing of the US Congress subcommittee on the topic. The current state of the Semantic Web is said to be comparable with that of the early days of the Web. Until very recently, growth has been linear, but signs of exponential growth are beginning to emerge. Given this promising situation, we should ask ourselves where and how we expect the Semantic Web to continue to grow in the near- to mid-term future. Our view is that the Semantic Web will come to the fore through a comprehensive integration with service orientation. In particular, we envisage that the combination of Semantic Web and SOAs will lead to the creation of a “service Web”—a Web where billions of parties are exposing and consuming billions services seamlessly and transparently and where all types of stakeholders, from large enterprises to SMEs and singleton end users, engage as peers consuming and providing services within a network of equals

An Ontology-based Collaborative Knowledge Management Network to Enhance the Reusability of Inter-organizational Knowledge

A number of knowledge management (KM) approaches based on individual organizational KM strategies and business requirements have been developed without taking system interoperation into consideration. In this paper, a collaborative inter-organizational KM network is proposed to allow various organizations to access and retrieve inter-organizational knowledge. While knowledge engineers can reuse the inter-organizational knowledge to create and evaluate its own organizational knowledge, general users benefit from the effectiveness and efficiency of searching for relevant inter-organizational knowledge within the networ

Ontological Implications of the Levels of Conceptual Interoperability Model

The Levels of Conceptual Interoperability Model (LCIM) was developed to cope with the different layers of interoperation of modeling & simulation applications. It introduced technical, syntactic, semantic, pragmatic, dynamic, and conceptual layers of interoperation and showed how they are related to the ideas of integratability, interoperability, and composability. This paper will be presented in the invited session Ontology Driven Interoperability for Agile Applications using Information Systems: Requirements and Applications for Agent Mediated Decision Support at WMSCI 2006

Using Simulation Systems for Decision Support

This chapter describes the use of simulation systems for decision support in support of real operations, which is the most challenging application domain in the discipline of modeling and simulation. To this end, the systems must be integrated as services into the operational infrastructure. To support discovery, selection, and composition of services, they need to be annotated regarding technical, syntactic, semantic, pragmatic, dynamic, and conceptual categories. The systems themselves must be complete and validated. The data must be obtainable, preferably via common protocols shared with the operational infrastructure. Agents and automated forces must produce situation adequate behavior. If these requirements for simulation systems and their annotations are fulfilled, decision support simulation can contribute significantly to the situational awareness up to cognitive levels of the decision maker

A conceptual model for semantically-based e-government portals

Issues of semantic interoperability and service integration for e-government portals are the domain of interest of the present paper. We propose a Conceptual Model for One-Stop e-Government Portals based on the Semantic Web Service technology. We describe our research into building the three basic ontologies and their integration with standard ontologies. The result is a project-independent reusable model. At the same time, we outline a simple methodology for applying the proposed conceptual model into a specific scenario
