RSAComb is an improved re-implementation of the combined approach for CQ answering over RSA ontologies described in [1].
Please note that the prototype mentioned in [1] is not available (and the contributors to this project have never seen it); therefore, this "re-implementation" could be completely different from that prototype (potentially using different tools and programming languages).
RSAComb has been used as a key part of ACQuA.
This project has been released as free and open source software and licensed under the Apache License 2.0.
Source code and documentation are available online on the RSAComb's GitHub repository. Releases can be found on GitHub as well.
