KAON2

AIFB, University of Karlsruhe (http://www.aifb.uni-karlsruhe.de)

KAON2 is an infrastructure for managing OWL-DL and SWRL ontologies. KAON2 provides the following features:

- an API for programmatic management of OWL-DL and SWRL ontologies,

- a stand-alone server providing access to ontologies in a distributed manner,

- an inference engine for answering queries,

- a module for extracting ontology instances from relational databases (available soon).

FOAM � Framework for Ontology Alignment and Mapping

AIFB, University of Karlsruhe (http://www.aifb.uni-karlsruhe.de)

FOAM allows the alignment of two OWL-DL ontologies. Identifying equal entities is achieved through comparisons with a large number of ontology features

and similarity measures. A threshold then determines which pairs should be finally aligned. Through machine learning or additional user

interaction results outperform recent methods for alignment.

Ontology evolution

OWL Evolution (evOWLution)

AIFB, University of Karlsruhe (http://www.aifb.uni-karlsruhe.de)

OWL Evolution is a software component that supports the methods for the consistent evolution of OWL ontologies. It builds on top of the KAON2 ontology management infrastructure. The implementation includes evolution strategies for various fragments of ontology languages, including OWL-DL, OWL-Lite and OWL-DLP, as well evolution strategies for logical consistency. Additionally it allows to plug-in further evolution strategies for structural consistency (to support additional sublanguages), logical consistency, and user-defined consistency. The OWL Evolution strategies can also rely on contextual information such as the confidence annotations of Text2Onto to guide the evolution process.
