Hi All,
Structured Dynamics and Ontotext have just released version 1.00
of UMBEL. This version is the first production-grade release of
this open source, reference ontology for the Web.
For more information and downloads, please see http://umbel.org.
In broad terms, here is what is included in the new version 1.00:
* A core structure of 27,917 reference concepts (RCs), an
increase of 36% over the prior version
* The clustering of those concepts into 33 mostly disjoint
SuperTypes (STs)
* Direct RC mapping to 444 PROTON classes
* Direct RC mapping to 257 DBpedia ontology classes
* An incomplete mapping to 671 GeoNames features
* Direct mapping of 16,884 RCs to Wikipedia (categories and
pages); 60% of UMBEL is now mapped to Wikipedia
* The linking of 2,130,021 unique Wikipedia pages via
3,935,148 predicate relations; all are characterized by one or
more STs with 876,125 also assigned a specific type
* And, some vocabulary changes, including some new and some
dropped predicates.
UMBEL's basic vocabulary can also be used for constructing
specific domain ontologies that can easily interoperate with this
and other systems.
Enjoy! We solicit and welcome your comments and contributions.
