Task-Structure analysis: a modularized approach for modeling knowledge intensive processes

R.M. Wong, S. Bhattacharyya
Proceedings of the 35th Annual Hawaii International Conference on System Sciences  
The objective of this paper is to demonstrate the application of the Task-Structure (TS) approach to identify the generic problemsolving components and their interrelationships in a knowledge intensive  ...  The TS approach emphasizes the identification and formalization, during a conceptualization stage, of the various problem-solving roles played by knowledge in the application task.  ...  Such analysis of the task structure directs attention to acquiring the appropriate domain models as 'stuff-ins' for problem solving.  ...

Groupware Task Analysis [chapter]

Martijn Van Welie, Gerrit Van Der Veer
2003 Human Factors and Ergonomics  
In addition a task analysis tool EUTERPE is described. EUTERPE is based on GTA and allows capturing of the task models and provides some basic analysis primitives.  ...  Groupware Task Analysis is a task analysis method that deals with the context of use of a system in the broadest sense.  ...  However performing a formal analysis of a task model requires a formal representation of the task model that is suitable for doing an analysis, especially for analyzing cooperation.  ...

Development of a knowledge model for managing schedule disturbance in steel-making

R. Roy *, B. A. Adesola, S. Thornton
2004 International Journal of Production Research  
In this paper the knowledge model distinguishes three knowledge categories: the task knowledge, the inference knowledge and the domain knowledge.  ...  A knowledge elicitation methodology called XPat [eXpert Process Knowledge Analysis Technique] combined with CommonKADS approach was used to capture process knowledge for managing schedule disturbance in  ...  Construction of the inference structure is realised by identifying first, the inference functions for the analysis task, and then synthetic tasks.  ...

The Synthesis Stage in the Software Agent Development Process [chapter]

Fernando Alonso, Sonia Frutos, Loïc Martínez, F. Javier Soriano
2005 Lecture Notes in Computer Science  
In most existing software agents methodologies, system analysis is dependent on an agent-oriented, object-oriented or knowledge-based design paradigm.  ...  This simplifies the complex transformation of the conceptual model produced during analysis into the physical model output at design time.  ...  Object Model Interaction Model Agent Model Conceptualization Conceptualization Initial Structural Model Initial Task Model Structural Model Environment Model Task Model ANALYSIS  ...
