"Enhancing FreeLing Rule-Based Dependency Grammars with Subcategorization Frames"

Despite the recent advances in parsing, significant efforts are needed to improve the current parsers performance, such as the enhancement of the argument/adjunct recognition. There is evidence that verb subcategorization frames can contribute to parser accuracy, but a number of issues remain open. The main aim of this paper is to show how subcategorization frames acquired from a syntactically annotated corpus and organized into fine-grained classes can improve the performance of two rulebased dependency grammars.
