72223S03-I Given the large and ever-growing volume of scientific information spread throughout the Internet, a researcher with limited time needs help to determine the most relevant documents to review. No satisfactory tools exist to retrieve the most relevant documents across different… More

72223-Research professionals need advanced search and retrieval technology to identify, assemble, and rank-for-relevance scientific and technical information resident on the Internet. This requirement is particularly challenging when utilizing the deep web in which most of the important data and… More

At the present time, no federated search engine exists that is capable of searching, aggregating, and ranking more than a small fraction of the scientific content produced by the research community at large and by DOE researchers in particular. Although thousands of sources of valuable content… More

High Energy Physics (HEP) experiments face major challenges in building interactive analysis environments for the unprecedented volume of data that will be gathered in the next generation of experiments at the Large Hadron Collider (LHC) and other accelerators. The current generation of HEP Grid… More

A major scalability problem of federated search engines, knowing which sources to search, occurs when a hundred or as many as a thousand or more sources are available to the researcher. It is not a good idea to search all possible sources for every query, as this places a heavy burden on the search… More

Scaling issues arise in federated search environments when the number of sources searched becomes large. These problems are not well understood, as few large-scale federated search environments exist. In particular, these problems have not been studied in distributed grid-based environments. This… More

Researchers are now beginning to use tools that allow them to retrieve relevant documents from the large and ever-growing volumes of scientific information spread throughout the Internet. Once these documents are gathered or identified, researchers still need help organizing, managing, and sharing… More

In searching for documents, traditional federated search engines emphasize the use of standard query parameters, such as author, title, and date range. Although most sources provide for a full-record search, users are left to guess at which terms might yield results. It would be much more useful… More

English-speaking federated search users are not easily able to search non-English sources of information. This leads to the loss of information potentially useful to scientists and researchers. This project will design and develop a prototype search application that takes a search query in English… More

Search engines that access pre-indexed documents are able to quickly refer users to related documents. However, the problem becomes harder when the search engine is federating sources in real-time with no access to pre-indexed data. This project will design, build, and deploy a federated search… More

No central catalog of all high-quality scientific and technical search engines exists at the present time. Consequently, researchers may not be able to access high quality content, because they do not know about some of the sources. This project will design and test various algorithms and build… More

Relevance ranking of documents retrieved from federated search sources is typically performed by analyzing the words in the document's summary information, which is provided by the underlying source. This type of analysis is highly dependent on the quality of the summary provided, which varies… More

A federated search engine that is capable of searching, aggregating, and ranking more than a small fraction of scientific content of interest to researchers does not exist. Consequently, scientific discoveries cannot be easily found and leveraged for further advancements. This project will… More

High Energy Physics (HEP) experiments face major challenges in building interactive analysis environments for the unprecedented volume of data that will be gathered in the next generation of experiments at the Large Hadron Collider (LHC) and other accelerators. The current generation of HEP Grid… More

DOE research is hindered by the fact that much quality scientific information is not published in English. No mechanism exists for researchers to search for foreign language documents in their native language, with automatic translation of results and documents. A multi-lingual federated search… More

It is difficult for DOE researchers to keep apprised of relevant scientific information given its rapid rate of growth. No mechanism exists to automatically discover, configure access to, or select sources for searching. This project will develop a suite of applications that discover new information… More

Both private companies and government agencies are faced with an enormous amount of text documents that are distributed over a network of computers and databases. Searching for specific documents is essential to the success of these organizations. Websites such as ScienceEducation.gov indicate that… More

The Department of Energy provides scientists, researchers, and the public with search engine access to high quality scientific and technical content. Because much of the content is highly technical in nature, many users require encyclopedia-quality background information. This project will develop… More

Federated search technology can facilitate scientific discovery by providing one-stop access to a large number of information sources. However, performance bottlenecks and limitations in the ability to retrieve the most relevant results limit the benefits of this technology to DOE researchers, to… More

The Department of Energy, particularly through the Office of Scientific and Technical Information (OSTI), provides access to high quality scientific and technical content to scientists, researchers, and the public through a number of science portals. Despite this service, thousands of additional… More

The ability to thoroughly search large numbers of scholarly information sources is vital to DOE researchers to accelerate scientific advances that address the nation's pressing energy and security problems. While large-scale federated search deployments provide the best hope of making research… More

Performance bottlenecks in federated search limit the benefits of the technology to DOE researchers, to other scientists and to the public. We will assess the performance bottlenecks of Deep Web Technologies' federated search technology in Phase I and make performance improvements in Phase II. We… More
