Be on the Alert!by Mary Schorn 15 Oct, 2009 in Products and Content Do you want to receive notification of the latest additions to key DOE/OSTI resources that contain research and development results, project descriptions, accomplishments, and more? It's as simple as registering for Science Accelerator Alerts and then choosing a topic or author of interest. You may either 1) conduct a search on your chosen topic/author and then select the 'Create an Alert' button on the search results page or 2) go directly to the Alerts Login page and login. Either of these approaches will take you to a page containing an 'Alert Profile'. Complete the profile, including the Alert frequency time frame desired, and save it. You will then receive Alerts at the e-mail address that you provide. Alerts joins the many other features on Science Accelerator that are available to assist with finding what you are seeking -- refining the search (search within a search), sorting the results, clustering, Wikipedia and EurekAlert! science news results, and selecting specific items of interest. Science Accelerator also provides feature searches, the capability to e-mail your results, and Web 2.0 features -- a Widget, an RSS feed, and the Share capability.

OSTI's Web Metrics - Partially Measuring Successby 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 our web servers deliver information to satisfy a user's request. Requests can take a variety of forms. Sometimes a user's request might be a search of a product such as Science Accelerator that brings back a hit list. Following up on this information transaction, a user might click on an item in the hit list to call up a single bibliographic citation delivered via a component database of Science Accelerator such as the Information Bridge or Energy Citations Database. Next, the user might call up the full text of a technical report. Another type of information transaction would occur when a user requests tens, hundreds, or thousands of bibliographic citations via our OAI or MARC xml services. In 1994, OSTI launched and hosted the first DOE web home page. From this small web presence, OSTI served 300,000 information transactions. In FY 2008, OSTI served over 84,000,000 information transactions, a 28,000% increase. While information transactions are of great use and give us a great metric relative to information dissemination, it is useful to more...

Tool Supports OSTI Mashupsby Mary Schorn 14 Jul, 2009 in Products and Content Did you know that science information is available via web "mashups"? Web "mashups" combine multiple products/services into a single application for the purpose of consolidating information with an easy-to-use interface. The Department of Energy (DOE) Office of Scientific and Technical Information (OSTI) uses "mashups" to return search results from Science Accelerator, Science.gov, and WorldWideScience.org. These "mashups" include external sources of information, in these cases from Wikipedia and EurekAlert!, that are provided as a service to the user for help with additional background information or with the ability to further study their topic. These "mashups" are made possible by OSTI's use of a federated search to perform all-encompassing searches of important databases and collections. Science Accelerator searches U.S. Department of Energy (DOE) databases of scientific and technical information representing billions of dollars of DOE research. Science.gov searches U.S. government agency scientific databases and web pages. WorldWideScience.org searches national and international scientific databases and portals. Federated searching provides each of the three products with one-stop simultaneous searching of multiple networked data resources via a single query. When a query is entered, it is sent to selected databases, collections, and/or web portals that are available for searching. The individual data resources send back results, which are ranked in relevance order and are provided to the user as "mashups". Users can examine these "mashups" to find specific results that contain information that is useful to...

Forms of STIby Tim Byrne 19 Jun, 2008 in Products and Content A comment I have heard on numerous occasions is that OSTI has a too many databases and search tools and it is difficult to know which to use. Well, I am sure that a lot of people do find the variety of OSTI resources to be a bit confusing, but it really takes different types of databases and search tools to cover all the different types of scientific and technical information (STI). Scientific and technical information has many forms, such as journal articles, technical reports, patents and e-prints. Each has its own publication route which requires its own method of acquisition. A traditional library is built by compiling a collection of books and periodicals for use by library patrons. In the electronic world, collections have expanded beyond the walls of the library. OSTI is able to create two different types of electronic collections. The first type is more like a traditional library in that OSTI compiles a collection of STI produced by or funded under the provenance of the Department of Energy on an OSTI computer. OSTI controls what goes into these collections and in what format. The OSTI databases that are of this sort include the full text documents in the Information Bridge and the bibliographic citations and summaries created for the Energy Citations Database, DOEpatents, and the DOE R&D Project Summaries. The second type of electronic collection is a virtual collection of STI outside of DOE. These collections contain STI that is of interest to DOE, but, for the most part, is not produced by DOE. The citations and full text documents in these virtual collections reside on the Internet in servers all over the world. OSTI has identified the locations of the STI and provides a means to search...

Now You Can Find Scientific Software at the DOE Science Acceleratorby Mary Schorn 04 Apr, 2008 in Products and Content The centralized software center of the U.S. Department of Energy (DOE) has been added to the DOE Science Accelerator search capability. This means that in addition to current and legacy research findings, patents, accomplishments and project descriptions, users of the Science Accelerator can now find federally funded scientific and technical software developed by DOE national laboratories, other facilities and DOE contractors. This software, licensed and distributed by the Energy Science and Technology Software Center (ESTSC), represents the latest in DOE technology and contains selected scientific and technical software from the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development (OECD). The DOE Science Accelerator is a gateway to key DOE databases and resources.

Sophisticated Yet Simple - The Technology Behind OSTI's E-print Network: Part 1by Sol Lederman 26 Feb, 2008 in Technology The E-print Network is one of OSTI's most popular and powerful research offerings yet few of its users know about the advanced technology that drives it and makes it simple to use. Professional researchers in basic and applied science are able to access over 5 million e-prints gathered from nearly 28,000 world-wide databases and web-sites. Numerous OSTI innovations ensure that the E-print Network's documents are of extremely high quality, are highly relevant to researchers, and are easy and quick to find. This is the first in a series of articles about the technology behind this very important component of the Science Accelerator. This article serves as an overview; subsequent articles will provide more technical information. The E-print Network is a federated search application. It federates (aggregates) search results from over 50 content databases in a number of scientific disciplines from a single user query. The E-print Network, however, uses federated search in an innovative way; One of the databases it searches is a special collection formed by harvesting over 1.3 million E-prints from nearly 28,000 hand-picked web-sites. A custom-designed crawler is responsible for performing the harvesting and custom software is used to build an index of the 1.3 million E-prints so that they can be searched quickly together with the non-harvested databases. Most E-print Network users are unaware that the application is, in fact, a blend of federated search and Google-like crawling technologies. This marriage of the two technologies reflects OSTI's insight in realizing that e-prints not only reside in certain well...

The Role of Federated Search at OSTIby Sol Lederman 19 Feb, 2008 in Technology Federated search is very much at the heart of OSTI's ability to realize its mission. OSTI provides a simple description of what federated search is and how it works in the OSTI environment. The best way to experience the tremendous value of federated search at OSTI is to try several of OSTI's flagship applications: These, and all, federated search applications search databases "live", which means there is no delay or "lag time" between when a collection is updated by its owner and when the new content can be searched. Science Accelerator provides searchable access to a number of science databases that OSTI manages. Its aim is to accelerate science discovery by greatly reducing the time and effort required for researchers to find relevant science information. Science.gov was OSTI's break-through federated search product; the first version was launched in December 2002. Science.gov provides access to more than 50 million pages of science information from 17 scientific and technical organizations via the collaboration of 13 federal agencies. WorldWideScience is a global science gateway to national and international scientific databases. The technology used to mine content from the deep web is called "federated search." While federated search is not the only search technology... Related Topics: federated search, osti, Science Accelerator, Science.gov, WorldWideScience.org (WWS) Read more... |
