¿Cómo y dónde concretamos la perspectiva de género en nuestra docencia universitaria? y ¿cómo desarrollamos la perspectiva de género con un enfoque transversal?

En materia de aprendizaje virtual, son numerosos los recursos que existen y se almacenan en repositorios. La tendencia hacia la estandarización de estos almacenes ha contribuido a mejorar la compartición, búsqueda y recuperación de la información, además de fomentar la interoperabilidad entre las diferentes plataformas existentes. Los metadatos que...

As Question Answering is a major research topic at the University of Alicante, this year two separate groups participated in the QA@CLEF track using different approaches. This paper describes the work of Alicante 1 group. Thinking of future developments, we have designed a modular framework based on XML that will easily let us integrate, combine an...

This paper describes the development of an image retrieval system that combines probabilistic and ontological information 1 . The process is divided in two different stages: indexing and retrieval. Three information flows have been created with different kind of information each one: word forms, stems and stemmed bigrams. The final result com-bines...

This paper describes the participation of the University of Alicante (UA) in CLEF 2005 image retrieval task. For this purpose we used an image retrieval system based on probabilistic information combined with ontological information and a feedback technique. Several information streams are created using different sources: stems, words and bigrams;...

This paper describes the novelties introduced in the Question Answering system de-veloped in the Natural Language Processing and Information Systems Group at the University of Alicante for QA@CLEF 2005 campaign with respect to our previous par-ticipations. Thinking of future developments, this year we have designed a modular framework based on XML...

This paper describes the architecture, operation and results obtained with the Question Answering prototype for Spanish developed in the Department of Language Processing and Information Systems at the University of Alicante for the CLEF-2004 Spanish monolingual QA evaluation task. Our system is based on the prototype developed for the CLEF-2003 Sp...

This paper presents the approach used by the University of Alicante in the ImageCLEF 2004 adhoc retrieval task. This task is performed through multilingual search requests (topics) against an historic photographic collection in which images are accompanied with English captions. This approach uses these captions to perform retrieval and is based on...

This paper presents the discourse annotation followed in Cast3LB, a Spanish corpus annotated with several information sources (morphological, syntactic, semantic and coreferential) at syntactic, semantic and discourse level. 3LB annotation scheme has been developed for three languages (Spanish, Catalan and Basque). Human annotators have used a set...

This paper presents a novel approach to the development of anaphoric annotation of large corpora based on the use of semantic information to help the annotation process. The anaphora annotation scheme has been developed from a multilingual point of view in order to annotate three corpora: one for Catalan, one for Basque and one for Spanish. An anap...

We present a tool, called 3LB-SAT, for the semantic tagging of multilingual corpora. Main features of this tool are that it is word-oriented, allows different formats for input corpus (TBF format, PenTreebank Bracketted Format and XML) and uses EuroWordnet for searching the word sense in four languages. Presentamos una herramienta, llamada 3LB-SAT,...

Building a NLP system requires the adding of linguistic phenomena resolution. One of the most relevant tasks regarding to these phenomena is the coreference resolution. Coreference is defined as a semantic phenomenon and, therefore, apart from the morphological and syntactic information that is highly useful, adding semantic sources improves the ca...

This thesis presents a deep study of the influence and the use of syntactic roles and semantic information in the pronominal anaphora resolution for Spanish and, specifically, the generated by personal, demonstrative, reflexive and omitted pronouns. A combination of both knowledge sources is proposed in order to propose a linguistic, scientific and...

This paper presents an algorithm for identifying noun phrase antecedents of third person personal pronouns, demonstrative pronouns, reexive pronouns, and omitted pronouns (zero pronouns) in unrestricted Spanish texts. We define a list of constraints and preferences for different types of pronominal expressions, and we document in detail the import...

In this paper, a method to solve pronominal anaphora using full parsing is presented. This approach applies, like other traditional approaches do, a set of constraints and preferences to the list of candidates previously appeared in the text. In our approach, for Spanish, semantic criteria for the resolution process is also added. Furthermore, ther...

This paper describes a Natural Lan- guage Learning method that extracts knowledge in the form of semantic pat- terns with ontology elements associated to syntactic components in the text. The method combines the use of EuroWord- Net's ontological concepts and the cor- rect sense of each word assigned by a Word Sense Disambiguation(WSD) module to ex...

This paper describes a Natural Language Learning method that extracts knowledge in the form of semantic patterns with ontology elements associated to syntactic components in the text. The method combines the use of EuroWordNet 's ontological concepts and the correct sense of each word assigned by a Word Sense Disambiguation(WSD) module to extract t...

In this paper we present a whole Natural Language Process- ing (NLP) system for Spanish. The core of this system is the parser, which uses the grammatical formalism Lexical-Functional Grammars (LFG). The system uses the Specification Marks Method in order to resolve the lexical ambiguity. Another important component of this system is the anaphora r...

Tendencies in Natural Language Processing (NLP) systems go towards the study of the semantic knowledge that can be extracted from the words within a context. For this reason, semantic information addition is necessary for the definition of new NLP strategies. In this paper, a method oriented to pronominal anaphora resolution in Spanish is presente...

In this paper we present a whole Natural Language Processing (NLP) system for Spanish. The core of this system is the parser, which uses the grammatical formalism Lexical-Functional Grammars (LFG). Another important component of this system is the anaphora resolution module. To solve the anaphora, this module contains a method based on linguistic i...

The problem with using extensive lexical, syntactic and semantic resources is the large quantity of information that is provided, as well as all the different senses that each word has. To contribute to the resolution of this problem, this paper presents a tool for knowledge acquisition from WordNet, restricting and limiting the learning of word se...

In this paper we present an automatic mechanism for bilingual (Spanish-English) alignment of anaphoric expressions. For this purpose, two anaphora resolution systems were used. Both are based on linguistic preferences and constraints, for Spanish (SUPPAR) and for English (MARS). These systems have been independently developed and each of them is pr...

In this paper, an Interlingua mechanism called Interlingua Slot Structure (ISS) due to the fact that it is based on Slot Structure (SS) presented in Ferrández et al. (1997a, 1997b), is proposed. SS stores the lexical, syntactic, morphologic and semantic information of every constituent of the grammar. The mechanism ISS allows to carry out translati...

Resumen Este trabajo presenta la instrumentación y evaluación de un nuevo sistema de tutoriza-ción no presencial en línea.

En este trabajo se presenta una propuesta para incorporar información semántica en el proceso de análisis sintáctico parcial. La propuesta está basada en el método IRSAS para textos restringidos y extiende su acción a textos no restringidos con el uso de un recurso léxico de propósito general (WordNet). Tras la generación de una serie de patrones s...
