Guessing the grammatical function of a non-root f-structure in LFG.
In: IWPT 2009 - 11th International Conference on Parsing Technologies, 7-9 October 2009, Paris, France.
Lexical-Functional Grammar (Kaplan and Bresnan, 1982) f-structures are bilexical labelled dependency representations. We show that the Naive Bayes classifier is able to guess missing grammatical function labels (i.e. bilexical dependency labels) with reasonably high accuracy (82–91%). In the experiments we use f-structure parser
output for English and German Europarl data, automatically “broken” by replacing grammatical function labels with a generic UNKNOWN label and asking the classifier to restore the label.
