We present a grand challenge to build a corpus that will include all of the world’s languages, in a consistent structure that permits large-scale cross-linguistic processing, enabling the study of universal linguistics. The focal data types, bilingual texts and lexicons, relate each language to one of a set of reference languages. We propose that the ability to train systems to translate into a...

In principle, a network can transfer data at nearly the speed of light. Today’s Internet, however, is much slower: our measurements show that latencies are typically more than one, and often more than two orders of magnitude larger than the lower bound implied by the speed of light. Closing this gap would not only add value to today’s Internet applications, but might also open the door to excit...

RAISE is a research project aimed at building a framework and platform that supports the integration of multiple existing models, simulations, and data. The grand challenge is to facilitate the process of pulling the independently created models together. In our approach, RAISE, we explore a reflective middleware to address challenges of integrated simulation environments in which interoperabil...

The Accelerated Model for Climate and Energy (ACME) is a leading-edge climate and Earth system model designed to address U.S. Department of Energy (DOE) mission needs. The ACME project involves collaboration between seven National Laboratories, the National Center for Atmospheric Research, four academic institutions, and one private-sector company. The ACME project funds ongoing efforts to ensu...

A decade after its first beginnings, the grand challenge of building automatic systems that translate speech has grown into an active research area, a focus for speech and language researchers worldwide. Workshops, conferences, sessions, journal issues are devoted to it, and research is supported by governments in Asia, Europe and the US. The problem has attracted much attention, as practical n...

Simulation has become the evaluation method of choice for many areas of computer networking research. However, most existing network simulation packages have severe limitations on the size and complexity of the network being modeled. Simulated networks of just a few thousand network elements and a few thousand data ows will quickly exhaust the computing resources in any reasonably sized compute...

The state of knowledge and outstanding challenges and opportunities in global water cycle observations, research and modeling are briefly reviewed to set the stage for the reasons behind the new thrusts promoted by the World Climate Research Programme (WCRP) as Grand Challenges to be addressed on a 5to 10-year time frame. Those focused on water are led by the GEWEX (Global Energy and Water Exch...

“Grand challenges” are formulations of global problems that can be plausibly addressed through coordinated and collaborative effort. In this Special Research Forum, we showcase management research that examines societal problems that individuals, organizations, communities, and nations face around the world. We develop a framework to guide future research to provide systematic empirical evidenc...
