FreeLing is an open-source multilingual language processing library providing a wide range of language analyzers for several languages. It offers text processing and language annotation facilities to natural language processing application developers, simplifying the task of building those applications. FreeLing is customizable and extensible. Developers(More)
Resumen: Hoy en día el análisis discursivo automático es un tema de investigación relevante. Sin embargo, no existen analizadores del discurso para textos en español. El primer paso para desarrollar esta herramienta es la segmentación discursiva. En este artículo presentamos DiSeg, el primer segmentador discursivo para el español que utiliza el marco de la(More)
Automatic deep parsing is necessary for any NLP applications requiring a certain level of semantic representation. One of the goals of the KNOW project is the development of wide-coverage deep parsing grammars whose outcome will be open to the scientific community. In this article we present a implementation of Spanish, Catalan and English grammars in the(More)
This paper presents ParTes, the first test suite in Spanish and Catalan for parsing qualitative evaluation. This resource is a hierarchical test suite of the representative syntactic structure and argument order phenomena. ParTes proposes a simplification of the qualitative evaluation by contributing to the automatization of this task.
In this paper we present a classifier that solves a certain kind of ambiguities in syntactic structure for Spanish, namely, ambiguities as to the point of adjunction of a prepositional phrase in the syntactic structure of a sentence (PP attachment). As a starting point, we used EsTxala dependency grammar for Spanish, integrated within FreeLing, with an(More)
At present, automatic discourse analysis is a relevant research topic in the field of NLP. However, discourse is one of the phenomena most difficult to process. Although discourse parsers have been already developed for several languages, this tool does not exist for Cata-lan. In order to implement this kind of parser, the first step is to develop a(More)
Despite the recent advances in parsing, significant efforts are needed to improve the current parsers performance, such as the enhancement of the argument/adjunct recognition. There is evidence that verb subcategorization frames can contribute to parser accuracy, but a number of issues remain open. The main aim of this paper is to show how subcategorization(More)
