"I am delighted to provide such a positive progress report just six months after fellow federal agency heads joined the White House in launching the Big Data Initiative", stated NSF Director Subra Suresh. "By funding the fundamental research to enable new types of collaborations - multi-disciplinary teams and communities - and with the start of an exciting competition, today we are realizing plans to advance the foundational science and engineering of Big Data, fortifying U.S. competitiveness for decades to come."
"To get the most value from the massive biological data sets we are now able to collect, we need better ways of managing and analyzing the information they contain", stated NIH Director Francis S. Collins. "The new awards that NIH is funding will help address these technological challenges - and ultimately help accelerate research to improve health - by developing methods for extracting important, biomedically relevant information from large amounts of complex data."
The eight projects announced today run the gamut of scientific techniques for big data management, new data analytic approaches, and e-science collaboration environments with possible future applications in a variety of fields, such as physics, economics and medicine.
"Data represents a transformative new currency for science, engineering, and education", stated Farnam Jahanian, assistant director for NSF's Directorate for Computer and Information Science and Engineering. "By advancing the techniques and technologies for data management and knowledge extraction, these new research awards help to realize the enormous opportunity to capitalize on the transformative potential of data."
NSF, along with NASA and the Department of Energy, also announced the start of an idea-generating challenge series, opening additional avenues for innovation in seizing the opportunities afforded by Big Data science and engineering. The competition will be run by the NASA Tournament Lab (NTL), a collaboration between Harvard University and TopCoder, a competitive community of digital creators.
The NTL platform and process allows U.S. government agencies to conduct high risk/high reward challenges in an open and transparent environment with predictable cost, measurable outcomes-based results and the potential to move quickly into unanticipated directions and new areas of software technology. Registration is open through October 13, 2012, for the first of four idea generation competitions in the series. Full competition details and registration information is available at the Ideation Challenge Phase website.
"Big Data is characterized not only by the enormous volume or the velocity of its generation, but also by the heterogeneity, diversity, and complexity of the data", stated Suzi Iacono, co-chair of the interagency Big Data Senior Steering Group, a part of the Networking and Information Technology Research and Development program and senior science advisor at NSF. "There are enormous opportunities to extract knowledge from these large-scale, diverse data sets, and to provide powerful new approaches to drive discovery and decision-making, and to make increasingly accurate predictions. We're excited about the awards we are making today and to see what the idea generation competition will yield."
At a Tech America event on Capitol Hill, Suzi Iacono announced the award recipients:
Big-data practice suggests that there is a trade-off between the speed of data ingestion, the ability to answer queries quickly (e.g., via indexing), and the freshness of data. This tradeoff has manifestations in the design of all types of storage systems. In this project the principal investigators show that this is not a fundamental tradeoff, but rather a tradeoff imposed by the choice of data structure. They depart from the use of traditional indexing methodologies to build storage systems that maintain indexing 200 times faster in databases with billions of entries.
The sheer volume and diversity of data present a new set of challenges in locating all of the data relevant to a particular line of scientific research. Taking full advantage of the unique data in the "long-tail of science" requires new tools specifically created to assist scientists in their search for relevant data sets. DataBridge supports advances in science and engineering by directly enabling and improving discovery of relevant scientific data across large, distributed and diverse collections using socio-metric networks. The system will also provide an easy means of publishing data through the DataBridge, and incentivize data producers to do so by enhancing collaboration and data-oriented networking.
This project explores the foundations of big data management with the ultimate goal of significantly improving the productivity in Big Data analytics by accelerating data exploration. It will develop open source software to express and optimize ad hoc data analytics. The results of this project will make it easier for domain experts to conduct complex data analysis on Big Data and on large computer clusters.
The goal of this project is to design and test mathematically well-founded algorithmic and statistical techniques for analyzing large scale, heterogeneous and so called noisy data. This project is motivated by the challenges in analyzing molecular biology data. The work will be tested on extensive cancer genome data, contributing to better health and new health information technologies, areas of national priority.
The project aims to develop new statistical and algorithmic approaches to natural generalizations of a class of standard machine learning problems. The resulting novel machine learning approaches are expected to benefit other scientific fields in which data points can be naturally modeled by sets of distributions, such as physics, psychology, economics, epidemiology, medicine and social network-analysis.
The goal of the project is to develop core techniques and software libraries to enable scalable, efficient, high-performance computing solutions for high-throughput DNA sequencing, also known as next-generation sequencing. The research will be conducted in the context of challenging problems in human genetics and metagenomics, in collaboration with domain specialists.
The objective of this project is to develop theory and algorithms to tackle the complexity of language processing, and to develop methods that approximate how the human brain works in processing language. The research also promises better algorithms for search engines, new approaches to understanding brain activity, and better recommendation systems for retailers.
