LogMap is a free and open-source scalable and logic-based ontology matching software.
LogMap incorporates reasoning and inconsistency functions and allows you to extract between classes, instances and properties.
LogMap includes the ontologyy matching systems (MATCHER) and a mapping debugging system (DEBUGGER).
You can also use LogMap to convert mappings from RDF-OAEI format to OWL.
Being developed using Java, LogMap is a cross-platform tool that can be used on any operating system that comes with Java support (e.g. Mac OS X, Windows, Linux).
Detailed instructions on how to install and use the LogMap utility on your Mac are available HERE.
Here are some key features of "LogMap":
· Match semantically rich ontologies containing tens of thousands of classes
· Offers sophisticated reasoning and repair techniques
· Helps users intervene during the matching process
· Java 1.6 or later
