Beyond Collecting: Connecting

by Dr. Walt Warnick 19 Nov, 2008 in Technology

by Walt Warnick and Sol Lederman

OSTI has embraced a new paradigm for sharing scientific and technical information (STI). Historically, OSTI has fulfilled its mission of providing STI to scientists, researchers, and the public by hosting, or collecting, documents and/or metadata. OSTI's new paradigm is to make content searchable that is often hosted by others; today, OSTI connects those seeking the content with the organizations that host it.

Pushing the Limits is Key to OSTI's Success

by Dr. Walt Warnick 09 Oct, 2008 in Technology

by Walt Warnick and Sol Lederman

While federated search is a core technology that OSTI employs to tackle challenges of sharing knowledge, the technology isn't perfect.  OSTI aggressively uses federated search because it does what no other search technology can do--inexpensively making dozens of non-Googleable databases searchable via a single query.  Two nagging limitations of federated search are that it can take 30 seconds to execute a search--which seems slow in the digital age--and hit lists are not exhaustive. 

To drive progress,...

Surviving a Technological Transformation

by Dr. Walt Warnick 02 Sep, 2008 in Technology

The life of every person in the world today has been shaped by successive technological transformations. The printing press transformed communication and education, beginning in the mid 15th century. Sailing and navigation technology of the late 15th century allowed Europeans to learn about other continents, beginning the global network of trade. Metal tools and firearms technology of the early 17th century enabled Europeans to colonize other continents and spread the fruits of European technology around the world. Railroads transformed transportation beginning in the early 19th century,...

OSTI and Reference Linking

by Daphne Evans 13 May, 2008 in Technology

OSTI actively supports the practice of Reference Linking. Also referred to as citation linking, reference linking adds value to technical reports and journal articles by hyperlinking the references at the end of the document. Authors frequently cite numerous supporting reports and articles. However, locating these cited works can be difficult. If...

Navigating Technological Transformation

by Dr. Walt Warnick 07 Apr, 2008 in Technology

Today, all of OSTI's information products are on the web. This is in sharp contrast to the situation as recently as the mid-1990s, when OSTI had no products on the web.

First becoming popular in 1994, the web quickly emerged as a transformational technology, and its potential for reshaping OSTI was apparent. Recognizing the opportunity to advance the OSTI mission, OSTI set out to capitalize on it as quickly as resources would allow by producing web applications to disseminate all manner of scientific and technical information (STI). A...

Federated Search - The Wave of the Future?: Part 2

by Dr. Walt Warnick 13 Mar, 2008 in Technology

by Walt Warnick and Sol Lederman

This is the second in a three part series of articles about the deficiencies of web crawling and indexing, the superiority of federated search to the serious researcher, and the value of OSTI federated search applications in advancing science. Part 1 identified a number of serious limitations of Google and the other crawlers. This article shows how federated search overcomes these limitations. The...

Federated Search - The Wave of the Future?: Part 1

by Dr. Walt Warnick 12 Mar, 2008 in Technology

by Walt Warnick and Sol Lederman

The web is growing.

For providing searchable access to the content that matters the most to scientists and researchers, Google and the other web crawlers can't keep up. Instead, growing numbers of scientists, researchers, and science attentive citizens turn to OSTI's federated search applications for high quality research material that Google can't find. And, given fundamental limitations on how web crawlers find content, those conducting research will derive even more...

Sophisticated Yet Simple - The Technology Behind OSTI's E-print Network: Part 2

by Sol Lederman 05 Mar, 2008 in Technology

In Part 1 of this series I provided an overview of the technology that drives the E-print Network. In this article I will provide some detail about how the harvested collection, the "E-prints on Web Sites" component of the E-print Network, is constructed. In Part 3, I will discuss the technology of the portion of the E-print Network that relies on...
