    In an electronic and cybernetic world, when one is faced with the task of devising different kinds of interaction among participants, it is worth reflecting that, out of the many and various activities which people engage in, there is one kind of activity which has been cultivated, practised and performed for thousands of years by all members of society. This is the playing of games

    Modelling Discourse-related terminology in OntoLingAnnot’s ontologies

    Get PDF
    Recently, computational linguists have shown great interest in discourse annotation in an attempt to capture the internal relations in texts. With this aim, we have formalized the linguistic knowledge associated to discourse into different linguistic ontologies. In this paper, we present the most prominent discourse-related terms and concepts included in the ontologies of the OntoLingAnnot annotation model. They show the different units, values, attributes, relations, layers and strata included in the discourse annotation level of the OntoLingAnnot model, within which these ontologies are included, used and evaluated

    Vacuum Nodes and Anomalies in Quantum Theories

    We show that nodal points of ground states of some quantum systems with magnetic interactions can be identified in simple geometric terms. We analyse in detail two different archetypical systems: i) a planar rotor with a non-trivial magnetic flux Φ\Phi, ii) Hall effect on a torus. In the case of the planar rotor we show that the level repulsion generated by any reflection invariant potential VV is encoded in the nodal structure of the unique vacuum for θ=π\theta=\pi. In the second case we prove that the nodes of the first Landau level for unit magnetic charge appear at the crossing of the two non-contractible circles α\alpha_-, β\beta_- with holonomies hα(A)=hβ(A)=1h_{\alpha_-}(A)= h_{\beta_-}(A)=-1 for any reflection invariant potential VV. This property illustrates the geometric origin of the quantum translation anomaly.Comment: 14 pages, 2 ps-figures, to appear in Commun. Math. Phy

    Enriching Ontologies with Multilingual Information

    Multilinguality in ontologies has become an impending need for institutions worldwide that have to deal with data and linguistic resources in different natural languages. Since most ontologies are developed in one language, obtaining multilingual ontologies implies to localize or adapt them to a concrete language and culture community. As the adaptation of the ontology conceptualization demands considerable efforts, we propose to modify the ontology terminological layer by associating an external repository of linguistic data to the ontology. With this aim we provide a model called Linguistic Information Repository (LIR) that associated to the ontology meta-model allows terminological layer localization

    Contribuciones al diagnóstico del trastorno específico del lenguaje por medio de la repetición de pseudopalabras

    Get PDF
    Se presentan dos listas de pseudopalabras para la evaluación de la memoria fonológica de trabajo para el diagnóstico del trastorno específico del lenguaje. Una lista está constituida por pseudopalabras compuestas de sílabas frecuentes, y la otra por sílabas no frecuentes. Se acompañan de las instrucciones para su administración y de un baremo provisional realizado con niños de 5 y 7 años. La importancia de la tarea de repetición de pseudopalabras para el diagnóstico del trastorno específico del lenguaje se basa, por una parte, en que se ha comprobado que es la mejor forma de medir la capacidad del almacén fonológico de la memoria de trabajo, ya que se deben llevar a cabo tareas de discriminación de la señal acústica, transformación de la secuencia acústico-fonética en sus fonemas constituyentes, codificación de la información acústica en una representación fonológica, mantenimiento del orden de esta representación en la memoria de trabajo, y planificación y ejecución de la respuesta, sin que se pongan en marcha procesos de arriba abajo desde el significado. Y por otra parte, parece comprobado que el origen del trastorno específico del lenguaje está en la limitación de la capacidad del mencionado almacén fonológico que afecta, en primer lugar, a la adquisición de vocabulario, y, en segundo lugar, al desarrollo de la morfosintaxis.------------------Two lists of nonwords are proposed to evaluate the phonological working memory for diagnostic of specific language impairment. One list is made up of nonwords whose syllables are frequent and the other of nonwords whose syllables are not frequent. These lists are accompanied by instructions for their performance and by provisional norms carried out on 5- and 7-year-old children. On one hand, the importance of the task of nonword repetition for diagnostic of specific language impairment is based on works which reliably prove that it is the best tool to measure the capacity of phonological store of working memory, because it is necessary to implement tasks like discriminating the acoustic signal, converting the acoustic-phonetic sequence into phonemes, encoding acoustic information into a phonological representation, keeping the order of this representation in working memory, and planning and implementing the response; and these psycholinguistic activities must be carried out without activating top-down processes from the meaning. On the other hand, it seems proved that the origin of specific language impairment lies in the limitation of capacity of phonological store which affects, firstly, vocabulary acquisition, and, secondly, morphosyntax development

    Mapping Kitaev's quantum double lattice models to Levin and Wen's string-net models

    Full text link
    We exhibit a mapping identifying Kitaev's quantum double lattice models explicitly as a subclass of Levin and Wen's string net models via a completion of the local Hilbert spaces with auxiliary degrees of freedom. This identification allows to carry over to these string net models the representation-theoretic classification of the excitations in quantum double models, as well as define them in arbitrary lattices, and provides an illustration of the abstract notion of Morita equivalence. The possibility of generalising the map to broader classes of string nets is considered.Comment: 8 pages, 6 eps figures; v2: matches published versio
