A Translation Engine In Support Of Context-Level Interoperability, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The support of context-level interoperability demands increasing attention in today’s arena of semantics-oriented decision-support systems. Unlike data-oriented exchange, such semantic interoperability must venture beyond the elementary communication of discrete data values and endeavor to translate between significantly more expressive, context-rich representations. Further, support of this level of interoperability must not require a contamination of the native perspective embedded within each participant’s representation. Offered as a foundation upon which specific interoperability solutions can be developed, this paper presents a service-oriented framework supporting an extensible set of translation paradigms to effectively connect expressive ontology-based environments. Fundamental to this capability is the notion …

Knowledge Management Enterprise Services (Kmes): Concepts And Implementation Principles, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The purpose of this paper is to present concepts and implementation principles related to the design and development of reusable software services that are capable of assisting users at the operational level. Knowledge Management Enterprise Services (KMES) are an implementation of the service-oriented architecture paradigm, with a focus on the exchange of data within the meaningful context of a particular application (i.e., knowledge) domain. This requires a KMES service to incorporate a high level representation of this knowledge domain in the form of an ontology that is shared among all collaborating services within the application environment and at the same …

Elements Of Human Decision-Making, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

The purpose of this paper is to present some understandings of the human problem-solving activity that we have gained in the Collaborative Agent Design Research Center (CADRC) over the past two decades. Since we feel strongly that the human decision-maker should be an integral component of any computer-based decision-support system, it follows that we would have endeavored to incorporate many of the elements that appear to be important to the user in the design of these systems. The complexity of the human cognitive system is evidenced by the large body of literature that describes problem-solving behavior and the relatively fewer …

Decision-Support Systems: Notions, Prototypes, And In-Use Applications With Emphasis On Military Applications, Jens G. Pohl, Arthur Chapman, Kym Jason Pohl, Jonathan Primrose, Adam Wozniak

Collaborative Agent Design (CAD) Research Center

This report describes work performed by the Collaborative Agent Design Research Center (CADRC) over the past several years in the design and implementation of collaborative, computer-based, decision-support systems, mostly for military applications. In these systems multiple components, either program modules or separate processes (i.e., software agents), cooperate with each other and human decision makers to solve complex problems. The components are essentially of two types: knowledge-based narrow domain experts that provide services to other agents (i.e., service-agents); and, more autonomous agents (i.e., object-agents) that represent the interests of selected objects in high level information representation schemas.

Based on the notion …

Adapting To The Information Age, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

This paper draws attention to the profound changes that human civilization is experiencing as it moves from an industrial environment into an information environment, in which unprecedented emphasis is placed on the knowledge and capabilities of the individual. A clear distinction is drawn between data and information in relationship to computer-based facilities, and the transition of data-processing to the higher levels of information and knowledge representation in quasi intelligent decision-support systems. It is argued that the cultivation of its human capital becomes a foundational requirement for the success of a knowledge-based organization. In such an organization traditional practices of hierarchical, …

The Second Generation Integrated Collaborative Decision Making (Icdm) Model: A Three-Tier Approach To Agent-Based, Decision-Support Systems, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Ten years ago the CAD Research Center at California Polytechnic University in San Luis Obispo, California identified a standard framework for agent-based, decision support systems. Employing inter-process and inference engine technologies of the time, the CAD Research Center termed this ‘blueprint’ the Integrated Collaborative Decision-Making (ICDM) framework. Over the past twelve years ICDM has been successfully used as a foundation in several systems. These systems focus on a wide range of domains of application including architectural design and ship cargo stowage. Success of the ICDM framework in conjunction with the availability of newer technologies has prompted an evolutionary leap in …

The Round Table Model: A Web-Oriented, Agent-Based Approach To Decision-Support Applications, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

Not unlike King Arthur relying on the infamous Round Table as the setting for consultation with his most trusted experts, agent-based, decision-support systems provide human decision makers with a means of solving complex problems through collaboration with collections of both human and computer-based expert agents. The Round Table Framework provides a formalized architecture together with a set of development and execution tools which can be utilized to design, develop, and execute agent-based, decision-support applications. Based on a three-tier architecture, Round Table incorporates forefront technologies including distributed-object servers, inference engines, and web-based presentation to provide a framework for collaborative, agent-based decision …

Koala: An Object-Agent Design System, Kym J. Pohl, Jens G. Pohl

Collaborative Agent Design (CAD) Research Center

This paper describes KOALA, a design system with primary focus on the predesign stage of architectural design. KOALA combines object-agent technology with high level representation to form a partnership between the human designer and the computer-based design environment. A diverse taxonomy of agents including Domain agents. Space agents, and Monitor agents work in a collaborative fashion to provide the human designer with expert evaluation and assistance in developing a design solution. Spaces, in their roles as agents attempt to formulate various design solutions based on individual perspectives through negotiation with other agents. The result is a highly interactive design environment …
