SciTech Connect: Subject and Author Filters

by Tim Byrne 24 Jul, 2013 in Products and Content

One of the nice features of SciTech Connect is the ability to filter search results by subject and author.  On the Search Results page, these filters are midway down the left side.

The full SciTech Connect database contains over 2.5 million citations.  Filtering the full database by subject [23 MB AVI] shows the top subject in the database to be materials science with 184,200 citations.  Not too far down the top ten list you will also find materials with another 127,916 citations.  While this shows that SciTech Connect is quite strong in this area, the rest of the top subjects are good indicators of the diversity of scientific disciplines found in SciTech Connect.  Note especially environmental sciences as the ninth most frequent subject term.

  • materials science (184,198)
  • elements (174,970)
  • physics (174,180)
  • organic compounds (172,389)
  • design (157,517)
  • oxygen compounds (145,684)
  • chemical reactions (142,736)
  • materials (127,924)
  • environmental sciences (127,863)
  • fuels (123,001)

Selecting the Electronic Full-Text tab and filtering by subject [18 MB AVI] will give you a significantly different list of top ten subjects.  Materials science is still high on the list, along with design and environmental sciences, but the other seven subjects are new. 

OSTI Partnering with Publishers on CrossRef and FundRef to Enhance Public Access to DOE Scientific and Technical Information

Throughout our history, the Office of Scientific and Technical Information (OSTI) has worked to make authoritative science information ever more efficiently available to researchers and the public alike. Our core mission – ensuring access to and preservation of U.S. Department of Energy (DOE) research results – has not changed. But the technology we apply to that mission has changed a lot over the past 20 years. By adopting Internet technology carefully and early, pioneering new advances in that technology to meet our needs and partnering with other stakeholders in the scientific and technical information community (STI), OSTI aspires to achieve our mission better than ever before.

In 1994, OSTI actually created the first DOE home page, and we have made significant strides into the Information Age ever since, defining new electronic exchange formats, creating collections of digitized scientific and technical information and establishing an energy science and technology virtual library. OSTI also has played a leading role in developing and adopting pioneering web tools such as federated search, the simultaneous search of multiple web databases in real time via a single search query, and relevance ranking, technology that allows search results to be returned in a ranked order relevant to the search query, to enhance the diffusion of scientific knowledge.

As we reported in the last issue of the Newsletter, as directed by the White House Office of Science and Technology Policy and requested by former DOE Office of Science Director Dr. William Brinkman, OSTI is now developing a gateway that will provide public access to the gold standard of scientific communications, peer-reviewed accepted manuscripts and scientific journal articles resulting from DOE research investments.

OSTI is committed to being a leader in making the web work for DOE science, and in...

Plasmas - The Greatest Show on Earth

Perhaps the most beautiful and eerie displays of light in our sky are a phenomenon known as the auroras. This natural glow of light in the sky in high latitude regions usually displays ribbons of colors from a fluorescent green to brilliant purple to a vivid crimson somewhat like an unexpected beautiful sunrise or sunset.  Observers often call it the greatest show on Earth.

Auroras are triggered by geomagnetic storms when gusts of solar plasma wind strike the Earth’s magnetic field; charged particles rain down over the north and south magnetic poles, lighting up the atmosphere and causing the air to glow. In the northern latitude, this display is known as the aurora borealis or northern lights and in the southern latitude, it is known as aurora australis or southern lights.  Like lightening, auroras are one of the few naturally-occurring plasmas found here on Earth.

Plasma science involving both natural and artificially produced plasma encompasses a variety of science disciplines ranging from plasma physics, atomic and molecular physics, chemistry, energy security, advanced space propulsion, and material science.  Plasma’s unique behaviors and characteristics make them useful in a large and growing number of scientific and industrial applications important to our universe.  

DOE researchers are making significant progress in this amazing field.  For example, researchers at the...

Out of the past and into the future

If you look closely, you can find fossilized material on the banks of the Norris Lake shoreline in Anderson County, Tennessee when the Tennessee Valley Authority (TVA) lowers the water level.  If you are really lucky, you will find traces of sea creatures or beautiful flora or fauna impressions encased between the freshly exposed layers of rock. These are ancient treasures from our country’s rich geological history.

A paleogeography reconstruction of the Earth took place some 56 to 34 million years ago during the Eocene geologic period of time .  At the beginning of the Eocene, high temperatures and warm oceans created a hothouse world.  Continents drifted toward their present positions. As Australia split from the southern continent, a cold water channel developed between the two continents and a global cooling trend began.  In western North America, mountain building started and huge lakes formed.  Oil shale was formed by deposition of silt and organic debris on lake beds and on the ocean floor.

Many of the oil shale deposits and fossil zones around the world were formed during this period of time.  The Green River Formation in the United States records 6 million years of Eocene sedimentation in a group of mountain lakes in the three basins of Colorado, Wyoming, and Utah. The U.S. Geological Survey estimates that 1.5 trillion barrels of shale oil are contained within Green River Formation’s oil shale. This formation is the richest and largest known oil shale resource in North America.

DOE researchers are making progress on the long road to...

Introducing SciTech Connect


Introducing SciTech Connect

With the release of SciTech Connect, OSTI is expanding its deployment of semantic search, an innovative technology to improve the quality and relevance of search results across the majority of its DOE content.  Semantic search is a way to enhance search accuracy contextually. Rather than relying on search algorithms that identify a specific query term, semantic search uses more complex contextual relationships among people, places and things. It is an especially effective search approach when a person truly is researching a topic (rather than trying to navigate to a particular destination).

OSTI Director Walt Warnick has said this about SciTech Connect:  “Now, with SciTech Connect, we are expanding deployment of innovative semantic search technology to make DOE R&D results easier to retrieve and thereby better serve our dual core mission – getting DOE results out to the scientific community and beyond, and getting the community’s results into DOE.”

SciTech Connect contains all the full-text documents and citations previously found in Information Bridge and Energy Citations Database. Thus, SciTech Connect contains over sixty-five years of energy-related citations created and/or collected by OSTI. There are over 2.5 million citations, including citations to 1.4 million journal articles, 364,000 of which have digital object identifiers (DOIs) linking to full-text articles on publishers’ websites.  SciTech Connect also has over 313,000 full-text DOE sponsored STI reports; most of these are post-1991, but close to 85,000 of the reports were published prior to 1990. 

We are gradually phasing out Information Bridge and Energy Citations Database (more information). These products  accounted for approximately half of the 298 million transactions OSTI handled in 2012. OSTI will work to ensure a smooth transition for patrons as it consolidates these...
