5 Unique Ways to Refine or Expand Result Sets with EBSCO Discovery Service

EBSCO Industries has developed a number of innovative search tools accessible on its flagship platform, EBSCOhost.  For instance, EBSCOhost offers a unique visual search option which we profiled in a 2011 blog post. EBSCO also produces the EBSCO Discovery Service (EDS), a customized index of an institution’s information resources (catalogs, institutional repositories, full-text subscription databases, etc.) that gives users access to the content through a single search form.  EDS also includes access to the EDS Base Index, which provides metadata for a wide range of materials, ranging from journals and conference proceedings to CDs and DVDs. EDS uses a technology called “platform blending” to provide relevant results from a variety of subject indexes (which the user must be subscribed to on the EBSCOhost platform).  The platform blending technology allows users to search by the subject headings from controlled vocabularies through the EDS platform.  Professional patent searchers may find this tool to be a useful way to efficiently search all of their organization’s non-patent literature resources through a single flexible interface.

I recently had the opportunity to test EDS, and I was particularly impressed by the variety of tools which the search platform offered for refining or expanding result sets within both the initial search form and the hit list.  EDS includes options to limit the search by discipline, subject, or content provider, and integrated searches and widgets may be used to expand the number of results.   After the jump, learn about five different ways users can expand or limit their result set on EDS!

The Pros and Cons of EBSCOhost’s Visual Search Form


Most search platforms give users access to multiple search forms, since each searcher has different needs and strategies.  Patent searchers need access to a wide variety of databases and search forms in order to locate all available prior art.  A command line interface allows the user to create extremely customized, flexible search strings, but a more structured form may help the user craft a search within certain fields or limiters they may have otherwise overlooked.  I was therefore particularly intrigued when I first saw the visual search option on the EBSCOhost platform.  The visual search form provides some unique tools for locating non-patent literature prior art, such as visualizations of relavency, collection of relevant documents while still viewing search results, and filtering documents by subject through selection of related keywords.
