The Spanish Resource Grammar (SRG) is an open-source multi-purpose large-coverage precise grammar for Spanish. It is grounded in the theoretical framework of Head-driven Phrase Structure Grammar (HPSG) and uses Minimal Recursion Semantics for the semantic representation (Copestake at al., 2005). The SRG is implemented within the Linguistic Knowledge Builder (LKB) system, based on the basic components of the LinGO Grammar Matrix.
To increase the grammar robustness, we have integrated as a pre-processing module FreeLing, an open-source language tool suite performing shallow processing functionalities, ranging from text tokenization to shallow parsing. FreeLing has integrated our morphological dictionary, enlarging its dictionary from 6,500 to 76,000 lemmas. This dictionary can be downloaded from here under the LGPL-LR license.
We are also investigating Machine Learning methods applied to the acquisition of the information contained in the lexicon of the SRG, in the framework of the projects AAILE (HUM2004-0511-C02-01/FILO) and AAILE-2 (HUM2007-61067/FILO), leaded by Núria Bel. See AAILE web page.
The SRG is been developed by Montserrat Marimon at the Institut Universitari de Lingüística Aplicada (IULA) of the Universitat Pompeu Fabra (UPF) and it is funded by the Juan de la Cierva program (MEC, Spain) within the TEXTERM-2 project (BFF2003-2111). The SRG is part of the DELPH-IN open-source repository of linguistic resources and tools for writing, testing and benchmarking, and efficiently processing HPSG grammars.
