Research Activities
Knowledge Acquisition
- Researcher into Conceptual Graphs as popularized by John Sowa
Conceptual Modeling
For a number of years, I have been engaged in various conceptual modeling projects and research efforts. Most of these projects use conceptual graphs. While I have done some work advancing fundamentals in the state of the art, most of my work has been in applying conceptual graphs to actual knowledge-intensive domains.
Conceptual Structures Community
- Editorial Board, Intl Conference on Conceptual Structures (ICCS), held annually.
- General Chair, 12th Intl. Conference on Conceptual Structures (ICCS 2004) , Huntsville, AL U.S.A.
- Author of CharGer, a free conceptual graph editor that has been used in over 70 countries.
Software Processes and Practices
In collaboration with Aldo de Moor, we have explored formal models of software development processes and practices, with the goal of identifying areas where process and practice do not match. Our initial explorations have been focused on software requirements development and we continue to explore this area of research.
I am also a member of the software engineering faculty who support the Master of Science in Software Engineering, and other software engineering activities.
Team Mental Models
I previously have collaborated with a multidisciplinary research team exploring the notion of mental models, especially with respect to how they affect the effectiveness of teams. We obtained a small URII (UAH-local) grant and published some of our work.
