Re: OpenDOAR: 1,000+ Repositories - More than 500 in BASE
Hello,
Congratulations to OpenDOAR also from BASE (Bielefeld Academic
Search Engine), OpenDOAR is one of the most important repository
registers for us.
At the end of October 2007, BASE has indexed the 500th
repository. At present BASE includes 519 sources, which means an
increase of some 80 % compared to November 2006 (283 sources).
For details please see
http://base.ub.uni-bielefeld.de/images/dokzahl_quellen.gif
(the blue line represents the number of documents, the red bar
graph represents the number of repositories).
Since OpenDOAR lists some repositories without OAI-interface, we
decided to show that BASE can also crawl repositories. At
special request of Nature Publishing, we crawled and indexed two
Nature repositories, which do not yet provide an OAI interface:
Nature Precedings and Nature's Signaling Gateway.
Primarily in international professional circles, the multilingual
search option in the BASE-Lab aroused great interest. Therefore
we decided to integrate the option into the BASE search forms. By
using the Eurovoc-Thesaurus you can now broaden your search. If
you choose "basic terms only" a search term will be searched in
up to 21 languages at the same time (no matter which language you
use), provided that the search term is included in Eurovoc (for
every language 6,500 basic terms are included). If you choose
"basic terms and used-for-terms" synonyms for this search term
will be searched additionally. All in all 239,000 terms are
included in Eurovoc.
