Resolution of Dropped Pronouns in a Phrase Structure Grammar Meltem Turhan Onur T. Şehitoğlu Dept. of Computer Engineering Middle East Technical University Ankara/Turkey In this work, intra-sentential resolution of Turkish dropped pronouns in a phrase structure grammar is studied. Turkish is a pro-drop and free constituent order language. The resolution scheme for dropped pronouns depends on the constituent order. We introduce resolution rules for different surface orders and propose an implementation for an HPSG based parser. Implementation is based on incremental processing of non-local referential index sets during parsing.
