Ann: Falcons (2008 Spring) - Towards searching and browsing the Sem antic Web with concept spaces.

Ann: Falcons -- a new search engine for the Semantic WebHi all,
We are pleased to announce that the Falcons system (a search engine for the Semantic Web) has been updated to a new version[1]. Compared to the last version [2], Falcons Object Search now enables navigating class hierarchies for query refinement. 
New features of the Falcons Object Search include: 
 -an index from classes to objects, besides an index from keywords to objects; 
 -class-inclusion reasoning on multiple vocabularies; 
 -class recommendation for navigating class hierarchies.
Currently, Falcons has indexed:
 - 7 million well-formed RDF documents,
 - 250 million RDF statements,
 - 34 million objects (individuals) on the Semantic Web,
 - 2 million concepts (classes and properties) on the Semantic Web,
 - and 4 thousand ontologies on the Semantic Web.
To make your RDF data quickly retrievable via Falcons, you can submit the URLs of your RDF data to Falcons at [3].
Have fun with Falcons :-)
Regards,
