Una gramática de dependencias basada en patrones de etiquetas

This paper describes a grammatical formalism, DepPattern, to write dependency grammars using Patterns of PoS tags augmented with lexical and morphological information. The formalism inherits ideas from Sinclair’s work and Pattern Grammar. In addition, a compiler was implemented so as to generate robust parsers from DepPattern grammars for 5 languages: Spanish, English, Galician, Portuguese, and French. These parsers identify dependencies which can be used to improve NLP applications such as extration of similar words.
