... transform Penn trees to a dependency format and then use memory-based learning to perform various graph transformations. One of the transformations is node relabelling, which adds function tags ... Conclusions and Future Research Our research has shown that machine- learning- based Cast3LB tag assignment as a post- processing step to raw tree parser output statisti- cally signi...

For example, “Ariane II rachète” (Ariane II buys) is classified as a person, due to the word “Ariane” contained in the lexico...

... Machine learning approaches to this prob- lem have been reasonably successful, operating pri- marily by recasting the problem as a classification task (e.g. Aone and Bennett (1995), McCarthy and Lehnert ... corpus-based approach. First, we propose and evaluate three extra-linguistic modifications to the machine learning framework, which together pro- vide substantial and statistic...

To write rules for a rule-based analyzer, and to produce an analyzer using machine- learning tech- niques, it is cruc...
