Federated Search: An Often Overlooked Example of e-Science

by Dr. Walt Warnick 12 Feb, 2010 in Products and Content

A term of art now catching on is “e-Science.”  According to Wikipedia, “The term e-Science (or eScience) is used to describe computationally intensive science that is carried out in highly distributed network environments, or science that uses immense data sets that require grid computing; the term sometimes includes technologies that enable distributed collaboration, such as the Access Grid. The term was created by John Taylor, the Director General of the United Kingdom's Office of Science and Technology in 1999 and was used to describe a large funding initiative starting in November 2000. Examples of the kind of science include social simulations, particle physics, earth sciences and bio-informatics.”

Why might the critical-point behavior of coauthorship networks be universal? The symmetry group of the associated concept space

by Dr. William Watson 02 Feb, 2010 in Products and Content

In December 2008, Luis Bettencourt and David Kaiser reported their findings[1] from studies of research collaboration networks, which included their discovery that, as coauthorship networks in a particular field reach the point of forming a single giant component of interconnected authors that dwarfs all other coauthor groups in that field, the growth near that point depends in a universal way on the average number <k> of coauthors per author.  In particular, the fraction of coauthor links that belong to the giant component appears to be proportional to (<k> - kc)0.35, where kc, which marks the critical point, depends on the research field.[2]  The remarkable fact is that the exponent, 0.35, fits the data for networks in several quite distinct fields.  This value apparently isn’t common to networks in general, though.  I had wondered what features of a network do determine the exponent’s value.

DOE Data: Would We, Could We...?

by Jannean Elliott 01 Feb, 2010 in Products and Content

I can’t remember how it went now, but as a child I skipped rope to a rhyme that included “would I, could I” somewhere in it.  Recently questions were asked about OSTI’s involvement with scientific research data.  Is OSTI planning to become a repository for numeric data?  Are we going to issue Digital Object Identifiers (DOIs) for datasets, and would we be telling people how to manage their data?  For some reason, the questions triggered the memory of that old refrain, but now I was thinking from an OSTI perspective, “would we, could we…?”

Federated Search - Don't Get Caught Taking the Narrow View of What is Possible

by Mark Martin 05 Nov, 2009 in Products and Content

 As with most things, all federated search products are not created equally. Recently, I ran across a situation where federated search was derided for lack of capability related to precision search and relevancy ranking. As is often the case, this derision is founded in a narrow view of federated search. The view that federated search is only capable of generically searching data stores or not providing relevance across the resources being searched is this narrow view of what the technology can achieve.

OSTI Connects with Universities Nationwide

by Linda McBrearty 22 Oct, 2009 in Products and Content

One of OSTI’s founding missions is to support education. From the early 1960s when OSTI provided educational materials on the atom and published the booklet called “Understanding the Atom” we have been committed to education. While information in OSTI databases can be used by teachers, students and parents for Kindergarten through High School, many of the technical documents and research findings are better suited for university studies.

OSTI’s databases contain thousands of university research projects that were either funded by DOE or sponsored through partnerships. Who needs this higher-level information? University students, professors and librarians need ready access to this information to advance scientific discovery! OSTI’s goal is to provide all of this information in an easily accessible, organized, online format that is available at no cost. And we’ve done just that! Now OSTI is focusing on how we can help communicate better and ensure that the DOE laboratory research communities have immediate access to these priceless resources. We’re working hard to connect with research universities across the nation to let them know about these great resources.
