The Next Generation Air Transportation System (NextGen) envisions a flexible, dynamic airspace structure that is better able to adapt to changing traffic conditions than today’s rigid system of airways and airspace sectors. However, to develop effective NextGen airspace concepts, a thorough understanding is needed of current airspace configuration practices, and of the constraints that influenc...

In decision making a key source of uncertainty is people’s perception of information which is influenced by their attitudes toward risk. Both, perception of information and risk attitude, affect the interpretation of information and hence the choice of suitable courses of action in a variety of contexts ranging from project planning to military operations. Visualization associated with the dyna...

This paper presents an experiment of parallel knowledge base development by subject matter experts, performed as part of the DARPA’s Rapid Knowledge Formation Program. It introduces the Disciple-RKF development environment used in this experiment and proposes design guidelines for systems that support authoring of problem solving knowledge by subject matter experts. Finally, it compares Discipl...

This paper examines the personalization of online training simulations which are a key modern approach in computer aided education. More specifically it focuses on the difficulties involved in authoring personalized training simulations. The composition of such systems is very difficult which has hampered their wide spread adoption [Joolingen, 03]. Presently adaptive training simulations can on...

Establishing adequacy of psychometric properties of an instrument involves acquisition and evaluation of evidence based on item content and internal structure. Content validity evidence consists of subject matter experts providing quantitative ratings of the extent to which items are a representative sample of targeted domain. Evidence of internal structure includes factor analytic studies and ...

Mixed-initiative learning integrates complementary human and automated reasoning, taking advantage of their respective reasoning styles and computational strengths in order to solve complex learning problems. Mixed-initiative learning is at the basis of the Disciple approach for developing intelligent agents where a subject matter expert teaches an agent how to perform complex problem solving t...

There is a rapidly growing body of work in the use of Embodied Conversational Agents (ECA) to convey complex contextual relationships through verbal and non-verbal communication, in domains ranging from military C2 to e-learning. In these applications the subject matter expert is often naïve to the technical requirements of ECAs. ENGAGE (the Extensible Natural Gesture Animation Generation Engin...

Purpose – The importance of involving subject matter experts (SMEs) in ERP implementations is well established. SMEs’ knowledge of business and system processes are critical to conducting gap analyses and configuring enterprise systems. But what happens to SMEs on completion of the implementation phase? Prior qualitative research found that some organizations return SMEs to their old department...
