BASE - Bielefeld Academic Search Engine
http://www.base-search.net/index.php?i=a
The Search EngineBASE is the name of the multi-disciplinary search
engine for scientifically relevant web resources which was created and
developed by Bielefeld University Library. It is based on search
technology provided by FAST Search & Transfer, a Norwegian company. At
present BASE includes some 7.2 million documents originating form 519
sources.
As the open access movement grows and prospers, more and more repository
servers come into being which use the "Open Archives Initiative Protocol
for Metadata Harvesting" (OAI-PMH) for providing their contents.
For the BASE project OAI metadata from scientific repository servers are
collected by a so-called "harvester" and are indexed by means of FAST
software.
BASE is a registered OAI service provider and contributes to the
European project "Digital Repository Infrastructure Vision for European
Research" (DRIVER) since June 2006.
In addition to OAI metadata the library indexes selected web sites and
local data collections, which can be searched via one single search
interface in one go.
In comparison to commercial search engines, BASE is distinguished for
the following features:
- Intellectually selected resources
- Only document servers that comply with the specific requirements of
scientific quality and relevance are included
- A data resources inventory provides transparency in the searches
- Searches full text plus meta data (depending on the resource)
- Discloses web resources of the "Deep Web", which are ignored by
commercial search engines or get lost in the vast quantity of hits.
- The display of search results includes precise bibliographic data (if
provided in the resource)
- Several options for sorting the result list
- "Refine your search result" options (authors, resources, document
type, language etc.)
