SD, Ontotext Release First Production-Grade UMBEL
CORALVILLE, IA, February 15, 2011 -- Structured Dynamics and Ontotext today released -- after four years of iterative refinement -- version 1.00 of UMBEL. This version is the first production-grade release of this open source, reference ontology for the Web. UMBEL's current implementation is the result of much practical experience.
UMBEL's 28,000 reference concepts and their relationships help organize, link and present heterogeneous datasets and information on the Web. UMBEL lowers the time and effort to develop, maintain and use ontologies, and to align them with other content.
"We held off on designating a version 1.00 [of UMBEL] until it had been tested and deployed sufficiently to warrant production use," said Michael Bergman, CEO of Structured Dynamics and one of the two co-founding editors of UMBEL with Frédérick Giasson. "We're pleased to signal that UMBEL is now ready for prime time," he added.
"This is a major step forward to provide a reference structure for knitting content together on the Web," said Ontotext's CEO, Atanas Kiryakov. "We plan to incorporate this new release immediately into our FactForge knowledge platform, already the largest and best performing reasoning engine for linked data," he added.
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
Both Kiryakov and Bergman emphasized this release was an important first step to linking UMBEL with Wikipedia as a "gold standard" for ontological, semantic Web and disambiguation purposes. They noted future releases will extend these mappings, including with other important reference structures on the Web.
