UMBEL v 0.80 Released

11/15/2010

Structured Dynamics and Ontotext announced the latest release of UMBEL, version 0.80. UMBEL (Upper Mapping and Binding Exchange Layer) has two roles. It is a vocabulary for building reference ontologies to guide the interoperation of domain information. It is also a reference ontology in its own right that contains about 21,000 general reference concepts.

Here are the major changes in UMBEL v. 0.80.

  • #1: Clarification of Dual Role - this version clarifies and separates files for UMBEL's dual roles. The UMBEL Vocabulary of classes and predicates is used to describe domain ontologies, with the specific aim of promoting interoperability with external datasets and domains. The UMBEL Reference Concept Ontology with its 21,000 general reference concepts acts as binding nodes for mapping relevant Web-accessible content, also with the specific aim of promoting interoperability
  • #2: Reference Concepts and Predicate Simplification - another set of major changes was the simplification and streamlining of the predicates and construction of the UMBEL Vocabulary
  • #3: SuperTypes - the 21,000 reference concepts were "clustered" into more than 30 mostly disjoint natural groupings called SuperTypes. Fully 75% of the reference concepts in the UMBEL ontology are disjoint with one another
  • #4: OWL 2 Compliance - the vocabulary and ontology were converted to OWL 2 in order to: 1) use OWL reasoners; 2) load the full UMBEL into leading ontology editors; 3) use the OWL API, consistent with many other ontology tools under development; and 4) take advantage of a trick in OWL 2 called “punning“, a technique that allows concepts to be used in ontologies as either classes or instances, depending on context, and
  • #5: Documentation and Packaging - documentation was streamlined and simplified and a new project Web site was unveiled.

This release is in preparation for a follow-on UMBEL v. 1.00. This next version will provide mappings to leading ontologies and knowledge bases, as well as the upgrade of existing Web services and other language support features.
