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 other systems.
