              Elliphant

Abstract: This thesis presents Elliphant, a machine learning system for classifying Spanish subject ellipsis as either referential or non-referential. Linguistically motivated features are incorporated in a system which performs a ternary classification: verbs with explicit subjects, verbs with omitted but referential subjects (zero pronouns), and verbs with no subject (impersonal constructions). To the best of our knowledge, this is the first attempt to automatically identify non-referential ellipsis in Spanish.

La relación entre fonética y fonología

(Relationship between Phonetics and Phonology)

B.A. Linguistics course: Phonetics and Phonology.

Resumen: Es una presentación exahustiva de los puntos de contacto entre ambas disciplinas desde los orígenes de la fonología en la Escuela de Kazán hasta las revisiones de The Sound Pattern of English: teoría de la marcación, fonología generativa natural, fonología autosegmental, fonología léxica y teoría de la optimicidad.

Generativismo, de lo transformacional a lo computacional

(On Generative Grammar: from transformational to computational)

B.A. Linguistics course: Syntax.


Resumen: Este trabajo es cuaderno de consulta para poder sitúar en el tiempo los conceptos de la gramática generativa. Cada término está definido y cada revisión de la teoría está ilustrada con un gráfico que la resume. Se recoge desde los orígenes del generativismo desde las ideas de la gramática de Port Royal hasta la Gramática Léxico-Funcional y la de Frase Generalizada.

Awarded by the Special Award “GESFOR GROUP. Information Technologies” and Honorable Mention in the VI Arquimedes National Contest of Introduction to University Research, Spanish Ministry of Education and Science, 2007.

Resumen: CORAL es un modelo teórico pensado para extraer información semántica a partir de patrones sintácticos frecuentes en español. Está información semántica se crea a partir de la combinación de la morfología y de la sintaxis. El modelo combina ideas procedientes de diferentes paradigmas lingüísiticos.

Abstract: In this study we present the patterns of semantic variation through a categorization of the affixes of Spanish terms for colors. For the categorization we take into account (i) the grammatical class of the derived color term, (ii) the grammatical class of the derivational basis, (iii) the semantic features of the derivational basis, ± color and ± primary color, (iv) the affix type and (v) the variation of meanings in the affix. We present the analysis of the lexical and the morphological relations of these terms as well as the definitions for the color term’s affixes. We compiled a corpus with all the Spanish terms for colors (563) and their definitions taken from the dictionaries DRAE, DUE, DEA and CLAVE.
