Extended HVS Parser

Download to your calendar using vCal

If you have a question about this talk, please contact Dr Marcus Tomalin .

In the talk, I will present several extensions to the HVS parser. First, the initialization of its parameters was modified using automatically extracted negative examples. Second, the HVS parser was extended so that it is able to produce not only right branching parse trees but also the left branching parse trees. Finally, the third modification enables the parser to process not only words on its input but also additional features. The automatically obtained lemmas and morphological tags were used as features and they significantly increased the performance. Because the original parser and the extended parser were implemented in GMTK (the Graphical Models Toolkit), a brief description of the implementation will be given.
