The developing cyberinfrastructure affects the knowledge system by which geological surveys collect, represent, and communicate their knowledge, and thereby influences their view of the geology. Consequences for four interacting aspects of the overall system (infrastructure, business models, geological framework, and surveying methods) are outlined. Although each reflects a different area of ex...

this paper examines the theoretical rationales and practical aspects of task-based language teaching (tblt) with particular reference to research findings in efl/esl contexts. the definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  moreover, fact...

Design problem solving is a complex activity involving a number of subtasks and a number of alternative methods potentially available for each subtask. The structure of tasks has been a key concern of recent research in task-oriented methodologies for knowledge-based systems (Chandrasekaran 1986; Clancey 1985; Steels 1990; McDermott 1988). One way to conduct a task analysis is to develop a task...

In this paper, an integrated framework for knowledge audit and capture using the task analysis approach is presented. We first identify the types of knowledge that could be ascribed to tasks and analyze a task by breaking it down into subtasks and task elements. We then identify the skills and knowledge required to perform the tasks at this level. The framework is validated and tested on an exp...

In task-based business environments, effective knowledge management relies on providing task-relevant information to fulfill the information needs of knowledge workers. This work proposes an adaptive task-based profiling approach to model workers’ task needs, namely information needs (profiles) on tasks. Meanwhile, a fuzzy analytical method is proposed to identify peer-groups with similar taskn...
