Les grammaires de construction au service de la morphologie lexicale ? Apports pour la description des noms-termes en allemand
2019
International audience; Contexte Le « goût » de la langue allemande pour la créativité lexicale, en particulier dans le domaine nominal, fait figure de lapalissade. Ceci est particulièrement vrai en discours spécialisés où les besoins en dénomination de nouveaux concepts passent, outre les différentes formes d’emprunts ou de néologismes de forme, par les deux procédés classiques que sont la dérivation et la composition. C’est dans ce contexte que la présente proposition de communication vise à interroger les apports des grammaires de construction appliquées à ces phénomènes – on parlera alors avec Booij (2017) de morphologie constructionnelle – pour une analyse de l’interface syntaxe-séma…
Disseny i desenvolupament d'exams a partir d'eines de web semàntica
2011
La Web Semàntica no és una proposta de futur. És una realitat. Davant del creixement caòtic de recursos i l'absència d'una organització clara del web actual, la web semàntica advoca per classificar, dotar d'estructura i anotar els recursos amb semàntica explícita processable per màquines. En aquest article presentem els resultats d'una investigació realitzada a la Universitat de Múrcia pel grup TECNOMOD i el GITE, que de manera multidisciplinar hem abordat l'aplicació d'un programa semàntic denominat OeLE en una assignatura virtual de la Titulació de Pedagogia. Es va dissenyar un entorn d'avaluació en xarxa compost pel programa OeLE i un sistema de consulta del feedback que OeLE proporciona…
A diffusion model account of normal and impaired readers.
2004
Acquired aphasics and dyslexics with even very profound word reading impairments have been shown to perform relatively well on the lexical decision task (e.g., Buchanan, Hildebrandt, & MacKinnon, 1999), but direct contrasts with unimpaired participants data is often complicated by extremely long reaction times for patient data. The dissociation between lexical decision and word naming performance shown by these patients is of theoretical importance, and here we present an analysis of processing underlying the lexical decision task. We are able to determine what aspects of performance are affected by acquired aphasics in the lexical decision task. We fit lexical decision data from aphasic pa…
Letter Position Coding Across Modalities: The Case of Braille Readers
2012
BackgroundThe question of how the brain encodes letter position in written words has attracted increasing attention in recent years. A number of models have recently been proposed to accommodate the fact that transposed-letter stimuli like jugde or caniso are perceptually very close to their base words.MethodologyHere we examined how letter position coding is attained in the tactile modality via Braille reading. The idea is that Braille word recognition may provide more serial processing than the visual modality, and this may produce differences in the input coding schemes employed to encode letters in written words. To that end, we conducted a lexical decision experiment with adult Braille…
Semantics for Managing Systems in Heterogeneous and Distributed Environment
2002
The problem of legacy systems collaboration is being solved. Particularly we look at the collaboration as workflow in a distributed and heterogeneous environment. Attention is paid to the description of semantics for workflow process definition languages. There are many solutions how semantics can be decomposed into logical fragments, but the problem of obtaining reusable components that are easy to compile into desired specific semantics still remains. We evolve the division of semantics by semantic aspects whose description is based on abstract data types (pre-built components) and connectors (meta-programs to produce the glue code) between them. This paper offers a way in which semantic …
Building Semantic Trees from XML Documents
2016
International audience; The distributed nature of the Web, as a decentralized system exchanging information between heterogeneous sources, has underlined the need to manage interoperability, i.e., the ability to automatically interpret information in Web documents exchanged between different sources, necessary for efficient information management and search applications. In this context, XML was introduced as a data representation standard that simplifies the tasks of interoperation and integration among heterogeneous data sources, allowing to represent data in (semi-) structured documents consisting of hierarchically nested elements and atomic attributes. However, while XML was shown most …
A novel XML document structure comparison framework based-on sub-tree commonalities and label semantics
2012
International audience; XML similarity evaluation has become a central issue in the database and information communities, its applications ranging over document clustering, version control, data integration and ranked retrieval. Various algorithms for comparing hierarchically structured data, XML documents in particular, have been proposed in the literature. Most of them make use of techniques for finding the edit distance between tree structures, XML documents being commonly modeled as Ordered Labeled Trees. Yet, a thorough investigation of current approaches led us to identify several similarity aspects, i.e., sub-tree related structural and semantic similarities, which are not sufficient…
Building Ontologies from XML Data Sources
2009
In this paper, we present a tool called X2OWL that aims at building an OWL ontology from an XML datasource. This method is based on XML schema to automatically generate the ontology structure, as well as, a set of mapping bridges. The presented method also includes a refinement step that allows to clean the mapping bridges and possibly to restructure the generated ontology.
Querying Dynamic and Context-Sensitive Metadata in Semantic Web
2005
RDF (core Semantic Web standard) is not originally appropriate for context representation, because of its initial focus on the ordinary Web resources, such as web pages, files, databases, services, etc., which structure and content are more or less stable. However, on the other hand, emerging industrial applications consider e.g. machines, processes, personnel, services for condition monitoring, remote diagnostics and maintenance, etc. to be specific classes of Web resources and thus a subject for semantic annotation. Such resources are naturally dynamic, not only from the point of view of changing values for some attributes (state of resource), but also from the point of view of changing “…
