Two decades of Ripple Down Rules research

Ripple Down Rules (RDR) were developed in answer to the problem of maintaining medium to large rule-based knowledge systems. Traditional approaches to knowledge-based systems gave little thought to maintenance as it was expected that extensive upfront domain analysis involving a highly trained specialist, the knowledge engineer, and the time-poor domain expert would produce a complete model cap...

Two decades of research on the biosynthesis of saccharides.

Two decades of sunfleck research: looking back to move forward.

The study of how plants make use of sunflecks, relatively short duration but high-intensity patches of light in the understory and shaded tree canopy, has been of interest for decades. The potential ecological significance of sunflecks was recognized early in the 20th century (Allee 1926, Evans 1956), and the first few studies attempting to quantify the contribution of sunflecks to carbon gain ...

Two Decades of Multiagent Teamwork Research: Past, Present, and Future

This paper discusses some of the recent cooperative multiagent systems work in the TEAMCORE lab at the University of Southern California. Based in part on an invited talk at the CARE 2010 workshop, we highlight how and why execution-time reasoning has been supplementing, or replacing, planning-time reasoning in such systems.
