WorldWideScience – Easy Access to Text, Multimedia, and Data!

WorldWideScience

 

For many years, scientific information was provided primarily in text-based formats, such as journal articles, conference proceedings, and technical reports.  Increasingly, however, scientists are communicating through multimedia formats (images, videos), and via direct access to their scientific data sets.  Information users face some unique challenges in finding scientific information, particularly when it can take several forms.  Imagine that a climatologist has created data sets detailing precipitation measurements for the North Slope of Alaska.  The climatologist might present these findings first at a meteorological conference, and the presentation might be taped and made available as a video of the conference.  Later, the climatologist publishes one or more technical reports, referring to the original data sets.  How does a user find all this relevant information?

WorldWideScience offers a solution to finding scientific information, regardless of format.  Simply by entering the search terms in a single search box, users can search over 90 databases from around the world.  Furthermore, the search results are segmented into text-based information (the “Papers” tab), images and videos (“Multimedia” tab), and data sets (“Data” tab).  It’s easy to view results in each tab, and users can quickly access relevant text, videos, and data sets.  A variety of English and non-English databases are searched, and WorldWideScience even provides multilingual translations capabilities for 10 languages.  As scientific communication becomes progressively more...

OSTI and DataCite – Easing Access, Citation and Reuse of Data

DataCite

 

OSTI joined DataCite  to facilitate finding, accessing, citation of, and reusing publicly available scientific research datasets produced by U.S. Department of Energy (DOE) – funded researchers.  Through the OSTI Data ID Service, Digital Object Identifiers (DOIs) are assigned to research datasets, then registered with DataCite.  When registered, these datasets are announced with other forms of STI made available by OSTI as part of its mission to advance science.

This service facilitates:

  • Easier finding of datasets across the international community of researchers via DataCite’s DOI resolving tools.
  • Linkage between DOE’s R&D documents and the underlying datasets that were generated during the work.
  • A standard way to include data in the accepted bibliographic citation framework.
  • A better way to ensure researchers can be sure they locate the exact dataset used in someone's previous work, thus allowing validation of results or a new use for that data.

OSTI became a member of DataCite in January 2011.

WorldWideScience and data

WorldWideScience

 

WorldWideScience.org now offers the capability to search scientific data collections.  Six new data sources have been added to WWS.org, representing a significant milestone in improving access to scientific data from around the world.  Users seeking scientific datasets can conduct a real-time, one-stop search and immediately gain access not only to the metadata but to the actual scientific data itself.

WorldWideScience.org’s unique federated searching capability meets many of the challenges users face in the discovery of scientific and numeric data.  Unless users are very familiar with a particular data center or know that specific datasets exist, it is very difficult to identify and locate scientific data.  WWS.org provides access to over 80 of the world’s most authoritative scientific information and data sources, all nationally sponsored or sanctioned.  Users can simultaneously search across many databases/collections in text, multimedia, and data formats, and receive consolidated, relevance-ranked results.  In most cases, links direct the user to the full text document; or in the case of scientific data sources, the user can often link directly to datasets.  As access to scientific data becomes increasingly important, WWS.org offers the ability to easily identify, search, and access this information – contributing to the spread of scientific knowledge and advancements worldwide.

DOE research videos available on ScienceCinema

ScienceCinema

 

Scientific videos highlighting research and development (R&D) sponsored by the U.S. Department of Energy (DOE) are available on ScienceCinema. ScienceCinema uses innovative, state-of-the-art audio indexing and speech recognition technology to enable users to quickly find video files produced by the DOE national laboratories, other DOE research facilities and CERN (the European Organization for Nuclear Research). When users search for scientific words and phrases, precise snippets of the video where the search term was spoken are provided along with a timeline.

More than 2,500 videos are currently available in ScienceCinema, and the database will continue to grow as new R&D-related videos are produced by DOE programs, labs and facilities and submitted to OSTI. Scientific videos, animations, interactive visualizations and other multimedia are expected to become an increasingly prominent form of scientific communications. ScienceCinema was recently recognized as one of DOE’s six new initiatives in the DOE Open Government Plan 2.0 for making the federal government more transparent, participatory and collaborative.

Science Accelerator Sign-up for ALERTS Now!

 

We’ve made tracking a science topic in key DOE/OSTI resources easy with the Science Accelerator Alerts service.  It's as simple as first registering for Science Accelerator Alerts and then proceeding along one of the following channels:

1) conduct a search on your chosen topic/author and then select the 'Create an Alert' button on the search results page;

2) go directly to the Alerts Login page and register.

Either of these methods will take you to a page containing an 'Alert Profile' form. Complete the profile, select the frequency of your Alerts and save. You will then receive Alerts via email and also create a personal account.

The Science Accelerator was developed as a tool to advance discovery and to deliver science information. It empowers you to search, via a single query, important information resources of the U.S. Department of Energy's (DOE's) scientific and technical information. These resources contain the results of DOE research and development (R&D) projects and programs, major R&D accomplishments, and recent research of interest to DOE. They enable you to explore significant DOE discoveries, learn about DOE Nobel Prize Winners, access and search scientific e-prints, locate science...

How to Integrate Anything on the Web

by Dr. Walt Warnick 03 Aug, 2011 in Technology
Computer Integration

 

OSTI is especially proud of its web integration work whereby we take multiple web pages, documents, and web databases and make them appear to the user as if they were an integrated whole.   Once the sources are virtually integrated by OSTI, the virtual collection becomes searchable via a single query.  Because information on the web appears in a variety of formats, from HTML web pages, to PDF documents, to searchable databases, OSTI has developed and uses a suite of integration approaches to make them searchable via single query.  

OSTI has two goals that make it critical for us to understand multiple solutions for integrating science content on the web.  First, we make DOE science information widely available and searchable by appropriate audienceswherever they may be; and second, we make science information from around the world searchable by DOE researchers.  Since migrating to a fully electronic operationin the late 1990s, OSTI has met these goals by deploying various search architectures for integrating content via the web.

Within the information science circles that we engage in, we are well known for our pioneering work with the integration technology known as federated search. However, there are other, possibly lesser known,  technologies that we employ to integrate web content.

To  integrate information sources which are not interoperable, we see three categories of solutions:  1) you can create a data warehouse where you copy the information items, standardize metadata, and host them on your own servers;  2) you can create a discovery...
