Collaborative Reasoning and Collaborative Ontology Development in CRAFT

Daniel Gruen, Jamie Rasmussen, Jiahui Liu, Susanne Hupfer, Steven Ross

We present CRAFT (Collaborative Reasoning and Analysis Framework and Toolkit), a tool for collaborative investigation, reasoning, and analysis. Analysts use CRAFT to represent their collective knowledge and reasoning via interconnected graphical models built upon a shared evolving ontology. These semantic models help connect analysts to digital information sources and to each other, and the aggregated knowledge and findings of many analysts may be analyzed and visualized. We also summarize the results of a preliminary user study of collaborative, implicit ontology evolution using this tool.
