What were really trying to do is give you more free time. A very important part of our con- stellation goal is to change the world. DEBORAH MCGUINNESS Spinning the Web A brilliant interdisciplinary group of research scientists at Rensselaer is imagining new avenues for the World Wide Web. The Tetherless World Constellation TWC launched in 2008 aims to revamp the Webs ability to handle information in ways that would benefit everyone from casual browsers to pioneering academic researchers. James Hendler Tetherless World Professor of Computer Web and Cognitive Sciences and Director of the Rensselaer Institute for Data Exploration and Applications is regarded as one of the nations most innovative professors. He is helping to guide TWC and its researchers through the emerging field called Web Science. Web Science seeks to understand the Web in its full richness exploring its underlying technologies and social and policy implications and developing new technologies to expand it and make it more useful. We want to keep the Web moving and growing keep building it and always ask what it needs said Professor Hendler. The main vehicle for this work is the Semantic Web a common framework that allows data to be shared and reused across application enterprise and community boundaries. Deborah McGuinness Tetherless World Senior Constellation Chair and Professor in the departments of Computer Science and Cognitive Science is a leading voice within this movement. One important project with which Professor McGuinness is currently involved has been spurred by a grant from the Bill Melinda Gates Foundation. According to UNICEF more than a quarter of children under age 5 worldwide are permanently stunted due to malnutrition. Professor McGuinness will serve as technical leader for a project that draws on the Semantic Web to integrate multidisciplinary data thereby understanding more fully the effects of risk factors on growth outcomes and by extension developing effective solutions that improve worldwide child health. A tall order Indeed but as Professor Hendler said A very important part of our constellation goal is to change the world. breaking boundaries 18
