Federated Search: Closing in on the Speed Gap

Many casual users of federated search criticize the technology for being slow to retrieve results. Serious researchers recognize the unique ability of federated search engines to mine the deep Web for quality science information that Google cannot find. These users recognize that there is no practical alternative to federated search for the best information. Still, everyone wants everything faster, and those users who are willing to trade quality for quickness focus on how federated search doesn't return results in "Google time."

OSTI begins to address the speed issue by displaying...

The Jordan Aha! Test for Visualizations

It is said that a picture is worth a thousand words.  Such is the justification and hope for visualizations.  Examples of enlightening visualizations are structural models of molecules like the carbon-60 Bucky Ball used in OSTI’s recent YouTube video.  The model shows a carbon atom at each intersection of molecular bonds. 

Another example of an enlightening visualization is Charles Joseph Minard’s famous graph showing the decreasing size of...

For Spreading Knowledge, the Optimum Investment Is Not the Minimum

For Spreading Knowledge, the Optimum Investment Is Not the Minimum

An earlier article derived the Knowledge Investment Curve.


Information sharing is an integral part of the R&D process. Thus, decision makers affect the pace of scientific progress when they determine the fraction of R&D dollars dedicated to sharing knowledge. Think of it this way: A program for sharing knowledge derived from scientific research has much in common with a scientific research program itself in that they share the common goal of advancing science.  When decision makers of...

The X-Portal Vision of the Future

by Peter Lincoln 05 Oct, 2009 in Technology

As OSTI Director Walt Warnick likes to say, today's Web is like the Model T Ford -- revolutionary but ready for vast improvement. This is especially true when it comes to making the Web work for science and technology. In that spirit I want to describe a new kind of Web Portal, one which has yet to be built. It is called the X-Portal.

An X-Portal provides comprehensive coverage for a specific science or technology community, where X refers to that community. In other words, an X-Portal for biofuels is a comprehensive biofuels portal. X = Neutron Science gives a comprehensive neutron...

OSTI's Web Metrics - Partially Measuring Success

by Mark Martin 24 Sep, 2009 in Technology

OSTI creates and deploys web-based information products to accomplish its mission.  One way to measure the success of this approach is to use web metrics to gauge and analyze the usage of the information we disseminate via our web- based products.

An "information transaction" is the largest and most broadly defined web metric we track at OSTI. We define an information transaction as a discrete information exchange between an information patron and OSTI's suite of web-based information services. An information transaction occurs when...

Ideas That Bind

by Moderator 10 Sep, 2009 in Technology

by David Kaiser (MIT) and Luis Bettencourt (LANL)

For some time, we and OSTI have been interested in the question of how new scientific ideas spread. What does it take for the "next big thing" to leap from one person's head to an active community of researchers? Do those shared ideas or techniques bind the community together more tightly than before, perhaps even helping to define a new research field that didn't exist before? And if so, how might we detect and measure such shifts in the space of researchers...

OSTI's Pioneering Technology Efforts

by Mark Martin 24 Jul, 2009 in Technology

A typical misconception I face when I tell people that I work within the government is that they think my job, even though it is in the technology arena, must move at a snail's pace relative to the commercial sector. This preconceived notion that our government crawls along relative to technology adoption and innovation - at least in my experience - is way off the mark.

Here at OSTI we can cite several examples where we have been on the bleeding edge of technological development. Not only have we been on the bleeding edge, in some cases we have been on that bleeding edge in...

Transparency of Scientific Information

by Mike Jennings 01 Jul, 2009 in Technology

As a coordinator of Web 2 media and product technology at OSTI, I've often wondered whether the stakeholders involved in the development of DOE scientific reports could benefit more from web innovations such as websites, blog sites, subscriptions, and "live" content. The commercial Web and its second generation of Web 2 innovations have certainly been relevant factors in the transparency equation for other types of information on the Web outside of science. Specifically, I suggest that Web innovations would complement electronic document innovations for the transparency of DOE scientific...
