Integration of syntactic and lexical information in a hierarchical dependency grammar
Cristina Barbero, Leonardo Lesmo, Vincenzo Lombardo · 1998
In this paper, we propose to introduce syntactic classes in a lexicalized formalism like dependency. Subcategories of words are organized hierarchically from a general, abstract level (syntactic categories) to a word-specific level (single lexical items). The formalism is linguistically perspicuous, and useful for processing. A parsing model is defined, that uses the hierarchical mixed-grain representation (compiled in a tabular form), thus benefitting from both general and specific information in different stages of processing.
