Migración de una gramática sintáctica parcial entre dos formalismos de unificación

Este trabajo presenta el proceso de migración de una gramática sintáctica del euskera de un formalismo a otro. Debido a diferencias en los formalismos y también en el tipo de gramáticas, la transición directa de una gramática a otra no es posible. Esto lleva a que la construcción de la nueva gramática por parte de un lingüista parta prácticamente de cero. Por ello se ha planteado, de manera paralela a la construcción manual de la gramática, un experimento consistente en derivar una gramática de manera semiautomática generando reglas partiendo de la gramática antigua y un corpus analizado con ésta. Este experimento ha servido por un lado para comprobar la viabilidad de obtener una nueva gramática de manera prácticamente automática, y a la vez ha valido para ayudar en el proceso de construcción manual de la gramática, sirviendo de punto de comparación y para detección de errores u omisiones

DFKI finite-state machine toolkit

Finite-state devices such as finite-state automata and finite-state transducers have been known since the emergence of computer science and are recently extensively used in many areas of language technology. The use of finite-state devices is mainly motivated by their time and space efficiency. In this paper we present the Finite-State Machine Toolkit for building, combining and optimizing the finite-state machines, developed at the Language Technology Lab of the German Research Center for Artificial Intelligence

Application of Finite-State Transducers to the Acquisition of Verb Subcategorization Information

This paper presents the design and implementation of a finite-state syntactic grammar of Basque that has been used with the objective of extracting information about verb subcategorization instances from newspaper texts. After a partial parser has built basic syntactic units such as noun phrases, prepositional phrases, and sentential complements, a finite-state parser performs syntactic disambiguation, determination of clause boundaries and filtering of the results, in order to obtain a verb occurrence together with its associated syntactic components, either complements or adjuncts. The set of occurrences for each verb is then filtered by statistical measures that distinguish arguments from adjuncts
