- There is a significant gap between the services provided by dedicated information systems and general desktop systems for document communication and preparation. This situation is a serious knowledge-management problem, which often results in information loss, poor communication, and confusion among users. Semantic desktops promise to bring knowledge-based services to common desktop applications and, ultimately, to support knowledge management by adding advanced functionality to familiar computing environments. By custom tailoring these systems to different application domains, it is possible to provide dedicated services that assist users in combining document handling and communication with structured workflow processes and the services provided by dedicated systems. This paper presents a model for developing custom-tailored document processing for semantic-desktop systems. Our approach has been applied to the domain of military command and control, which as based on highly-structured document-driven processes. Key Words: semantic desktop, document-driven processes, semantic documents, planning

Combining Technical and Human-Centered Strategies for Decision Support in Command and Control - The ComPlan Approach
- 2008

Konferensbidrag (refereegranskat)abstract
- ComPlan (A Combined, Collaborative Command and Control Planning tool) is an approach to providing knowledge-based decision support in the context of command and control. It combines technical research on automated planning tools with human-centered research on mission planning. At its core, ComPlan uses interconnected views of a planning situation to present and manipulate aspects of a scenario. By using domain knowledge flexibly, it presents immediate and directly visible feedback on constraint violations of a plan, facilitates mental simulation of events, and provides support for synchronization of concurrently working mission planners. The conceptual framework of ComPlan is grounded on three main principles from human-centered research on command and control: transparency, graceful regulation, and event-based feedback. As a result, ComPlan provides a model for applying a human-centered perspective on plan authoring tools for command and control, and a demonstration for how to apply that model in an integrated plan-authoring environment.

Critique and Visualization as decision support for mass-casualty emergency management
- 2005

Konferensbidrag (refereegranskat)abstract
- Emergency management in highly dynamic situations consists of exploring options to solve a planning problem. This task can be supported through the use of visual cues that are based on domain knowledge of the current domain. We present an approach to use visualization of critical constraints in timelines and hierarchical views as decision support in mass-casualty emergency situations.

Domain-specific knowledge management in a Semantic Desktop
- 2009

Ingår i: Proceedings of I-KNOW '09 9th International Conference on Knowledge Management and Knowledge Technologies. ; , s. 360-365

Konferensbidrag (refereegranskat)abstract
- Semantic Desktops hold promise to provide intelligent information-management environments that can respond to users’ needs. A critical requirement for creating such environments is that the underlying ontology reflects the context of work properly. For specialized work domains where people deal with rich information sources in a context-specific manner, there may be a significant amount of domain-specific information available in text documents, emails and other domain-dependent data sources. We propose that this can be exploited to great effect in a Semantic Desktop to provide much more effective knowledge management. In this paper, we present extensions to an existing semantic desktop through content- and structure-based information extraction, domain-specific ontological extensions as well as visualization of semantic entities. Our extensions are justified by needs in strategic decision making, where domain-specific, well-structured knowledge is available in documents and communications but scattered across the desktop. The consistent and efficient use of these resources by a group of co-workers is critical to success. With a domain-aware semantic desktop, we argue that decision makers will have a much better chance of successful sense making in strategic decision making.

Simulation as a tool for problem detection in rescue operation planning
- 2005

Ingår i: Proceedings of the Conference on Modeling and Simulation for Public Safety: SimSafe 2005.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Management and response in the case of an emergency is a very demanding task. Rescue missiuns can involve numerous individuals and teams working together to save lives and property. The outcome of a rescue mission depends to a large extent on the responding units' ability to co-operate and the overall co-ordination of their efforts. This in turn makes it imponant to investigate how to support the decision makers in emergency situations.

User-centric critiquing in command and control : the DKExpert and ComPlan approaches
- 2007
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis describes two approaches for using critiquing as decision support for military mission planning. In our work, we have drawn from both human-centered research as well as results on decision support systems research for military mission planning when devising approaches for knowledge acquisition and decision support for mission planning.Our two approaches build on a common set of requirements which have been developed as the consequence of both literature analyses as well as interview studies. In short, these criteria state that critiquing systems should be developed with transparency, ease of use and integration in traditional work flow in mind. The use of these criteria is illustrated in two approaches to decision support in two different settings: a collaborative real-time war-gaming simulation and a planning tool for training mission commanders.Our first approach is demonstrated by the DKExpert system, in which end-users can create feedback mechanisms for their own needs when playing a two-sided war-game scenario in the DKE simulation environment. In DKExpert, users can choose to trigger feedback during the game by instructing a rule engine to recognize critical situations. Our second approach, ComPlan, builds on the insights on knowledge and planning representation gained from DKExpert and introduces an explicit representation of planning operations, thereby allowing for better analysis of planning operations and user-controlled feedback. ComPlan also demonstrates a design for critiquing support systems that respects the traditional work practice of mission planners while allowing for intelligent analysis of military plans.
