Dependency Modification Framework

To add Stanford-like dependency collapsing to German dependency parsers, we have created a framework and a rule format that can be used to modify and adjust dependencies. We have successfully converted the Stanford collapsing rules to German and demonstrated that this approach improves the performance of a semantic similarity calculation.

This framework can be used for other tasks as well, e.g. event extraction.
