Metaphor and Genre: An Approach to improve the learning process of English for Aeronautics

This study suggests a theoretical framework for improving the teaching/ learning process of English employed in the Aeronautical discourse that brings together cognitive learning strategies, Genre Analysis and the Contemporary theory of Metaphor (Lakoff and Johnson 1980; Lakoff 1993). It maintains that cognitive strategies such as imagery, deduction, inference and grouping can be enhanced by means of metaphor and genre awareness in the context of content based approach to language learning. A list of image metaphors and conceptual metaphors which comes from the terminological database METACITEC is provided. The metaphorical terms from the area of Aeronautics have been taken from specialised dictionaries and have been categorised according to the conceptual metaphors they respond to, by establishing the source domains and the target domains, as well as the semantic networks found. This information makes reference to the internal mappings underlying the discourse of aeronautics reflected in five aviation accident case studies which are related to accident reports from the National Transportation Safety Board (NTSB) and provides an important source for designing language teaching tasks. La Lingüística Cognitiva y el Análisis del Género han contribuido a la mejora de la enseñanza de segundas lenguas y, en particular, al desarrollo de la competencia lingüística de los alumnos de inglés para fines específicos. Este trabajo pretende perfeccionar los procesos de enseñanza y el aprendizaje del lenguaje empleado en el discurso aeronáutico por medio de la práctica de estrategias cognitivas y prestando atención a la Teoría del análisis del género y a la Teoría contemporánea de la metáfora (Lakoff y Johnson 1980; Lakoff 1993). Con el propósito de crear recursos didácticos en los que se apliquen estrategias metafóricas, se ha elaborado un listado de metáforas de imagen y de metáforas conceptuales proveniente de la base de datos terminológica META-CITEC. Estos términos se han clasificado de acuerdo con las metáforas conceptuales y de imagen existentes en esta área de conocimiento. Para la enseñanza de este lenguaje de especialidad, se proponen las correspondencias y las proyecciones entre el dominio origen y el dominio meta que se han hallado en los informes de accidentes aéreos tomados de la Junta federal de la Seguridad en el Transporte (NTSB)

Rocks are human beings: researching the humanizing metaphor in earth science scientific texts

This paper describes a corpus-based analysis of the humanizing metaphor and supports that constitutive metaphor in science and technology may be highly metaphorical and active. The study, grounded in Lakoff’s Theory of Metaphor and in Langacker’s relational networks, consists of two phases: firstly, Earth Science metaphorical terms were extracted from databases and dictionaries and, then, contextualized by means of the “Wordsmith” tool in a digitalized corpus created to establish their productivity. Secondly, the terms were classified to disclose the main conceptual metaphors underlying them; then, the mappings and the relational networks of the metaphor were described. Results confirm the systematicity and productivity of the metaphor in this field, show evidence that metaphoricity of scientific terms is gradable, and support that Earth Science metaphors are not only created in terms of their concrete salient properties and attributes, but also on abstract human anthropocentric projections.

Types of metaphor in civil engineering communication

La metáfora y otros mecanismos imaginativos subyacentes al pensa- miento y lenguaje humanos pueden ser utilizados en el discurso diario y especializado (Lakoff y Johnson 1980; Lakoff y Nuñez 2000). Asimismo pueden aparecer en la comunicación no verbal (Forceville y Urios-Aparisi 2009; Littlemore et al. Este volumen).Partiendo de estudios cognitivos y de la teoría de integración conceptual (Fauconnier 1997; Fauconnier y Turner 2002), este artículo examina la presencia de la metáfora en la ingeniería. Primeramente, se analiza un corpus lingüístico procedente de artículos de investigación de ingeniería civil. Los datos revelan el uso de la metáfora antropomórfica, sobre todo en expresiones relativas a la salud, como “diagnóstico”, “auscultación” o “proceso de curación”. Se exploran además ejemplos de ingeniería cuya fuente son proyecciones conceptuales corporales. Finalmente, abordamos la función de la metáfora visual bajo la teoría de integración conceptual mediante representaciones de ingeniería que evocan la anatomía humana o animal. Metaphor and other imaginative mechanisms that underlie human thought and language such as metonymy are used in everyday and specialised discourse (Lakoff and Johnson 1980; Lakoff and Nuñez 2000) They can also be involved in non- verbal forms of communication (Forceville and Urios-Aparisi 2009; Littlemore et al. this volume). Drawing on metaphor cognitive studies and on conceptual integration theory (Fauconnier 1997; Fauconnier and Turner 2002) this paper examines the occurrence of metaphor in engineering. First, we analyse results from a linguistic corpus formed by research papers from civil engineering journals. These data reveal the use of anthropomorphic metaphor, especially related to health or medical mappings such as “diagnosing”, “auscultation” or “curing”. Then, we explore how engineering notions are instantiated by bodily conceptual mappings according to conceptual integration theory. Finally, the function of visual metaphor is examined with conceptual integration theory by using engineering images evoking parts of human or animal anatomy.

Exploring cognition processes in second language acquisition: the case of cognates and false-friends in EST

This article explores one aspect of the processing perspective in L2 learning in an EST context: the processing of new content words, in English, of the type ‘cognates’ and ‘false friends’, by Spanish speaking engineering students. The paper does not try to offer a comprehensive overview of language acquisition mechanisms, but rather it is intended to review more narrowly how our conceptual systems, governed by intricately linked networks of neural connections in the brain, make language development possible, creating, at the same time, some L2 processing problems. The case of ‘cognates and false friends’ in specialised contexts is brought here to illustrate some of the processing problems that the L2 learner has to confront, and how mappings in the visual, phonological and semantic (conceptual) brain structures function in second language processing of new vocabulary. Resumen Este artículo pretende reflexionar sobre un aspecto de la perspectiva del procesamiento de segundas lenguas (L2) en el contexto del ICT: el procesamiento de palabras nuevas, en inglés, conocidas como “cognados” y “falsos amigos”, por parte de estudiantes de ingeniería españoles. No se pretende ofrecer una visión completa de los mecanismos de adquisición del lenguaje, más bien se intenta mostrar cómo nuestro sistema conceptual, gobernado por una complicada red de conexiones neuronales en el cerebro, hace posible el desarrollo del lenguaje, aunque ello conlleve ciertas dificultades en el procesamiento de segundas lenguas. El caso de los “cognados” y los “falsos amigos”, en los lenguajes de especialidad, se trae para ilustrar algunos de los problemas de procesamiento que el estudiante de una lengua extranjera tiene que afrontar y el funcionamiento de las correspondencias entre las estructuras visuales, fonológicas y semánticas (conceptuales) del cerebro en el procesamiento de nuevo vocabulario.

Automated end user-centred adaptation of web components through automated description logic-based reasoning

Context: This paper addresses one of the major end-user development (EUD) challenges, namely, how to pack today?s EUD support tools with composable elements. This would give end users better access to more components which they can use to build a solution tailored to their own needs. The success of later end-user software engineering (EUSE) activities largely depends on how many components each tool has and how adaptable components are to multiple problem domains. Objective: A system for automatically adapting heterogeneous components to a common development environment would offer a sizeable saving of time and resources within the EUD support tool construction process. This paper presents an automated adaptation system for transforming EUD components to a standard format. Method: This system is based on the use of description logic. Based on a generic UML2 data model, this description logic is able to check whether an end-user component can be transformed to this modeling language through subsumption or as an instance of the UML2 model. Besides it automatically finds a consistent, non-ambiguous and finite set of XSLT mappings to automatically prepare data in order to leverage the component as part of a tool that conforms to the target UML2 component model. Results: The proposed system has been successfully applied to components from four prominent EUD tools. These components were automatically converted to a standard format. In order to validate the proposed system, rich internet applications (RIA) used as an operational support system for operators at a large services company were developed using automatically adapted standard format components. These RIAs would be impossible to develop using each EUD tool separately. Conclusion: The positive results of applying our system for automatically adapting components from current tool catalogues are indicative of the system?s effectiveness. Use of this system could foster the growth of web EUD component catalogues, leveraging a vast ecosystem of user-centred SaaS to further current EUSE trends.

Linked Data Rights 2.0: extension of ODRL for Licensing Linked Data

Linked Data assets (RDF triples, graphs, datasets, mappings...) can be object of protection by the intellectual property law, the database law or its access or publication be restricted by other legal reasons (personal data pro- tection, security reasons, etc.). Publishing a rights expression along with the digital asset, allows the rightsholder waiving some or all of the IP and database rights (leaving the work in the public domain), permitting some operations if certain conditions are satisfied (like giving attribution to the author) or simply reminding the audience that some rights are reserved.

Formalisation and experiences of R2RML-based SPARQL to SQL query translation using Morph

R2RML is used to specify transformations of data available in relational databases into materialised or virtual RDF datasets. SPARQL queries evaluated against virtual datasets are translated into SQL queries according to the R2RML mappings, so that they can be evaluated over the underlying relational database engines. In this paper we describe an extension of a well-known algorithm for SPARQL to SQL translation, originally formalised for RDBMS-backed triple stores, that takes into account R2RML mappings. We present the result of our implementation using queries from a synthetic benchmark and from three real use cases, and show that SPARQL queries can be in general evaluated as fast as the SQL queries that would have been generated by SQL experts if no R2RML mappings had been used.

Analysis of the suitability of existing medical ontologies for building a scalable semantic interoperability solution supporting multi-site collaboration in oncology

Semantic interoperability is essential to facilitate efficient collaboration in heterogeneous multi-site healthcare environments. The deployment of a semantic interoperability solution has the potential to enable a wide range of informatics supported applications in clinical care and research both within as ingle healthcare organization and in a network of organizations. At the same time, building and deploying a semantic interoperability solution may require significant effort to carryout data transformation and to harmonize the semantics of the information in the different systems. Our approach to semantic interoperability leverages existing healthcare standards and ontologies, focusing first on specific clinical domains and key applications, and gradually expanding the solution when needed. An important objective of this work is to create a semantic link between clinical research and care environments to enable applications such as streamlining the execution of multi-centric clinical trials, including the identification of eligible patients for the trials. This paper presents an analysis of the suitability of several widely-used medical ontologies in the clinical domain: SNOMED-CT, LOINC, MedDRA, to capture the semantics of the clinical trial eligibility criteria, of the clinical trial data (e.g., Clinical Report Forms), and of the corresponding patient record data that would enable the automatic identification of eligible patients. Next to the coverage provided by the ontologies we evaluate and compare the sizes of the sets of relevant concepts and their relative frequency to estimate the cost of data transformation, of building the necessary semantic mappings, and of extending the solution to new domains. This analysis shows that our approach is both feasible and scalable.

Using the Cross-Entropy Method for Control Optimization: A Case Study of See-and-Avoid on Unmanned Aerial Vehicles

This paper presents an adaptation of the Cross-Entropy (CE) method to optimize fuzzy logic controllers. The CE is a recently developed optimization method based on a general Monte-Carlo approach to combinatorial and continuous multi-extremal optimization and importance sampling. This work shows the application of this optimization method to optimize the inputs gains, the location and size of the different membership functions' sets of each variable, as well as the weight of each rule from the rule's base of a fuzzy logic controller (FLC). The control system approach presented in this work was designed to command the orientation of an unmanned aerial vehicle (UAV) to modify its trajectory for avoiding collisions. An onboard looking forward camera was used to sense the environment of the UAV. The information extracted by the image processing algorithm is the only input of the fuzzy control approach to avoid the collision with a predefined object. Real tests with a quadrotor have been done to corroborate the improved behavior of the optimized controllers at different stages of the optimization process.

Sola romani: morteros hidráulicos romanos en la Península Ibérica

En esta investigación se han analizado morteros de cal de cronología romana en el interior de la Península Ibérica. Para ello, se seleccionó una serie de muestras procedentes de diversos yacimientos, y de estructuras de carácter industrial. Estas muestras presentan aditivos cerámicos y conglomerantes de cal, como característica principal. Desde un principio el esfuerzo debía de centrarse en los fragmentos cerámicos presentes en los morteros. Para ello se documentaron varios morteros con aditivos cerámicos, a fin de conocer sus características básicas (componentes, distribución, micro-estratigrafía, granulometría, etc.). Por ello, y una vez tomadas las muestras, ésta fueron tratadas y procesadas para desarrollar una primera fase de estudio por medio de macroscopía. Se obtuvieron buenos resultados en cuanto a la caracterización visual de los morteros, localizando y documentando los fragmentos cerámicos. Durante la observación de dichos aditivos se observó que los fragmentos cerámicos tenían unas coronas o anillos de coloración que recorrían el borde, justo al contacto con la matriz de cal. Fueron seleccionados algunos fragmentos en los que eran más visibles dichos anillos. A fin de conocer la posible relación entre algunos yacimientos cercanos y la presencia de dicho anillo cromáticos se desarrolló una microscopía óptica polarizada, realizando láminas delgadas de las muestras y sobre los fragmentos cerámicos más determinantes, en concreto de una serie de enclaves del valle del Henares. Además de caracterizar microscópicamente los morteros, se observó que los anillos no eran un defecto visual ni una alteración física, producida tal vez por la extracción, la fase del corte o por la cocción de la cerámica. Tras analizar varios ejemplares se pudo apreciar que esos anillos eran habituales en todas las muestras y que se presentaban de diferente manera, es decir, que se observaban en granos cerámicos de diferentes características físicas (cochura, tamaño, situación con respecto del conglomerante, etc.). A fin de conocer los aspectos químicos de dicha alteración se seleccionó un grupo de muestras en las que los resultados macroscópicos habían sido muy claros, y en las que la microscopía óptica polarizada había determinado en los bordes, áreas adecuadas para otros análisis. Se realizó un mapeado o mapping de elementos químicos, a fin de saber qué podía estar sucediendo en esa interfaz entre el fragmento cerámico y la matriz de cal. Gracias a los resultados obtenidos se comprobó que existía una acumulación potencial de calcio tanto en el interior de los granos cerámicos como en el exterior, justo en la zona de contacto con el conglomerante, formando manchas que recorrían longitudinalmente el borde. Estos datos fueron muy útiles para llevar a cabo la siguiente fase de estudio, que permitiría conocer puntualmente qué estaba sucediendo químicamente en esa zona de contacto. Finalmente y con el objetivo de describir química y puntualmente este efecto en las adiciones cerámicas, se volvió a seleccionar una serie de muestras, escogidas esta vez en función de los granos cerámicos que cumpliesen unas variables estadísticas. Se eligieron granos con distintos tipos de cocciones, así como granos con tamaños diversos y granos con aditivo ceniciento en la matriz de cal, pensando que podrían ser las variables más útiles de interpretar de existir algún tipo de cambio químico entre la arcilla cocida y la matriz de cal. Tales variables se adaptaron a un sistema estadístico multi-varial y geométrico, con el objetivo de sintetizar los resultados y visualizar de forma óptima los datos en conjunto, como se ha comentado en varias ocasiones en este trabajo. Una vez seleccionados los granos por variables se procedió a realizar un análisis lineal y espectral semi-cuantitativo de SEM-EDX, con el que se caracterizaba químicamente una sección lineal del grano, desde la matriz de arcilla cocida de la cerámica hasta la matriz de cal –del interior al exterior del grano- pasando por el centro de la banda de reacción. Este análisis permitió determinar que se había producido una serie de cambios químicos porcentuales en los granos de cerámica. Dichos cambios se resumen en un incremento global de los porcentajes de calcio en el interior de las bandas de reacción de la cerámica, desde el borde mismo del anillo hasta el exterior. Así también se observaron picos porcentuales en el interfaz del fragmento cerámico con la matriz de cal, lo que confirmaba los resultados obtenidos por medio del mapping. Globalmente en todas las muestras se apreció un hombro en las gráficas de calcio a su paso por la zona de afección del anillo de reacción. Los restantes porcentajes de magnesio, silicio y aluminio se mantienen normales. En esta tesis se ha confirmado que dicho incremento global de calcio se acentúa en las muestras en donde no hay cenizas en la matriz de cal. Los casos correspondientes a estos granos sufren un incremento mayor que en el resto. La segunda variable que sufre un mayor incremento de calcio es la que corresponde a granos con buena cocción de la arcilla. Por lo tanto, parece que la tercera variable, la que corresponde con el tamaño del fragmento cerámico, no es decisiva. Por lo tanto, teniendo en cuenta la prueba visual de los anillos de reacción, y atendiendo a los resultados químicos, podríamos pensar que ese incremento de calcio en la banda de reacción de los fragmentos cerámicos se debió a una absorción de calcio en el interior de la arcilla cocida en la fase inmediatamente previa al fraguado, incluso durante el apagado de la cal. Es en este punto donde estaría la clave del cambio químico que se produce en esta interfaz, el calcio sílice-aluminato del que algunos autores ya han investigado. Esta absorción de calcio en el interior del grano no vendría sola, sino que generaría una costra de cal en el interfaz exterior de la cerámica, la cual ha sido observada químicamente por mapping y mineralógicamente por medio de microscopía óptica de polarización. La consecuencia de estos resultados es, primero, la mejora de nuestro conocimiento general acerca del factor hidráulico en los morteros. Asimismo se aprecia que la incorporación de materiales orgánicos como cenizas, puede alterar los porcentajes de calcio en el interior de los aditivos cerámicos, por lo que habría que sopesar, en trabajos futuros, si este tipo de material es adecuado o no en las mezclas destinadas a la restauración, así como seguir indagando en las propiedades de los morteros con la incorporación de aditivos orgánicos. Desde el punto de vista de la catalogación de los suelos industriales hidráulicos de época romana, además de mejorar la documentación incorporando micro-estratigrafías y granulometrías, la investigación de este material histórico constructivo mejora en cuanto a que se incorporan ensayos sencillos, que facilitan incluso la peritación de un estado de conservación por medio de una lupa binocular. Arqueológicamente hablando, es muy interesante correlacionar fábricas diferentes de estructuras situadas o bien en un mismo yacimiento, o bien en una misma área regional. Los estudios de caracterización y micro-estratigrafía no sólo aportan datos nuevos de cara a la restauración de morteros, sino que crean la posibilidad de generar patrones constructivos que sirvan de fósiles-guía para datar relativamente a unas estructuras o a otras. En lo referido a los resultados obtenidos en los diferentes complejos arqueológicos se ha observado una diferencia entre los morteros destinados a piletas y cubetas con respecto a los suelos industriales de uso indeterminado. La muestra correspondiente al yacimiento de Las Arenas no dispone de ninguna micro-estratigrafía, como sí por el contrario en las muestras obtenidas en Rotonda de Mejorada, Val de la Viña y La Magdalena. En estos enclaves las estructuras presentan grandes similitudes, con diferentes niveles constructivos empleando morteros de cal con áridos y gravas en las capas interiores, y áridos con adiciones cerámicas en las exteriores. En lo relativo a la granulometría las adiciones cerámicas de las muestras de Val de la Viña y La Magdalena presentan varias coincidencias en cuanto al tamaño de los granos y la distribución. Asimismo, de las muestras tomadas en La Magdalena, existe una gran diferencia entre las muestras MG1, MG2, MG3 y MG4 con respecto a las muestras MG5 y MG6, correspondientes éstas últimas a un mortero con fragmentos cerámicos de gran tamaño. Las estructuras EMG1 y EMG2, correspondientes a una cubeta y una pileta de La Magdalena, guardan similitud en lo referido a la micro-estratigrafía y a la granulometría. Se ha determinado que su función, así como su fabricación, debieron estar vinculadas a un mismo contexto cronocultural. Química y mineralógicamente, las muestras presentan características iguales, con presencia de un conglomerante de cal con áridos y aditivos cerámicos de diferentes cochuras. Destaca la muestra de Las Arenas, con un tamaño de los fragmentos cerámicos muy superior al resto, seguido de la estructura EMG3 de La Magdalena. Las muestras restantes de éste enclave, junto con las muestras recogidas en Val de la Viña y Rotonda de Mejorada presentan condiciones similares. En conclusión, los datos revelan que existían diferentes fábricas destinadas a distintas finalidades, y que las estructuras industriales empleaban aditivos cerámicos para la manipulación de productos con líquidos, de distintas densidades pero que requerían de cierto grado de hidraulicidad. ABSTRACT Lime Roman mortars from the Iberian Peninsula has been analyzed in this reesearch. A group of samples were selected from some sites and all the samples come from industrial structures. All this samples show ceramic additives. From the start, the effort was centered in the pieces of pottery that were found in the mortars. The samples were treated and processed to develop a first phase of the research using macroscopy. With this technique, great results were achieved in the characterization of mortars, the microstratigraphy and the location of the ceramic pieces. While observing these pieces, it was seen that the fragments of pottery had a ring bordering the piece. The pieces with the bigger and more vivid rings were chosen and they were analyzed by a polarized light microscope. The mortars were characterized microscopically and it also showed that the rings were not a physical alteration or a visual defect. After some more tests, the rings were a chemical change associated with the hydraulicity of the mortar. The best samples were selected and mappings of their chemical elements were performed in order to know what could be happening in the interface between the ceramic matrix fragment and lime. With the results obtained it was found that there was a potential; both calcium accumulation within the ceramic grains and outside, just in the area of contact with the binder, forming spots longitudinally along the edge. These data were very useful for carrying out the next phase of study, which would meet promptly what was happening chemically in the area of contact. Another group of samples were taken, and this time focused on ceramic grains that met a statistical variables. Grains were chosen with two types of cooking as well as grains with different sizes and grains with ash additive in the matrix of lime, thinking that might be the most logical to be some sort of chemical change between the baked clay and lime array variables . Such variables were adapted to a multi-varial and geometric statistical system in order to synthesize the results and optimally display the data together, as mentioned several times in this work. After selecting the variables grains proceeded to perform a linear and spectral analysis SEM-EDX. This analysis led to determine that the chemical changes were graduals. These changes are summarized in an increase in the percentages of calcium inside the reaction rim of ceramics, from the edge to the outer ring. So percentage increasing is also observed at the interface of the ceramic matrix fragment with lime, confirming the results obtained by the mapping. Overall in all samples can be seen a shoulder in graphic calcium through the area of the ring reaction condition. The remaining percentages of magnesium, silicon and aluminum are usual. We have promptly confirmed that the increase of calcium is accentuated in samples where there is no ash and lime matrix. Cases for these grains suffer a greater increase than the rest. The second variable suffering more calcium is increased corresponding to good cooking grains with clay. Therefore, it appears that the variable size of the fragment is not critical. Therefore, considering the visual tests to the rings and their response to chemical results, we might think that increasing calcium inside the ceramic fragments was due to an injection of calcium inside clay in the run-up to the setting phase. It is at this point that would be the key to the chemical change that occurs at this interface, silica-calcium aluminate some authors have already investigated. This injection of calcium into the grain does not come alone, but generate a lime crust on the outside interface of ceramics, which we tested for mapping is real in our samples. The consequence of these results is the improvement of our understanding of historical hydraulic factor in building materials, such as mortar. For example, knowing that the incorporation of organic materials such as ash powder, may be detrimental to the injection of calcium inside the ceramic additives. Archaeologically speaking, it's very interesting to correlate different factories or structures located on a single site, or in the same regional area. Characterization studies and microstratigraphy not only provide new information to help restore mortars, but create the possibility of generating constructive patterns that serve as guide fossils to determinate the age of the structures. With regard to the results obtained in different archaeological sites it has seen a difference between mortars of pools or sinks with respect to industrial floors of undetermined use. The sample of the site of Las Arenas does not have any micro-stratigraphy, as if instead in the samples obtained in Rotonda de Mejorada, Val de la Viña and La Magdalena sites. In these settlements the structures are really similar, with different construction levels using lime mortars with aggregates and gravel in the inner layers, and ceramic aggregates as external additions. With regard to the grain size of the ceramic additions Val de la Viña and La Magdalena samples has several coincidences about the size of grains and distribution. Also, samples taken at La Magdalena, there is a difference between the MG1, MG2, MG3 and MG4 samples and the MG5 and MG6 samples, so the last corresponding to a mortar samples with larger ceramic fragments. The EMG1 and EMG2 structures, corresponding to a bucket and a pool of La Magdalena settlement, have similarities with regard to micro-stratigraphy and grain size. It has been determined that the function and manufacturing must be linked with a same chronocultural context.

A taste of the technical cuisine: metals and other ingredients

According to cognitive linguistics, language has an experiential origin based on perception, sensory motor activities and our knowledge of the world. Our thought operates by establishing similarities, links and associations that enable us to talk about one thing in terms of another as shown in the example of love as a journey (Lakoff and Johnson, 1980). Metaphor and metonymy are conceptual and linguistic tools that make possible most of these cognitive operations. Since metaphor is an essential element of human communication, the discourse of specialised disciplines includes metaphorical mappings and numerous examples of metaphorical expressions, for example in economics, where business is mapped in terms of war (White, 2004; Herrera & White, 2000), electrotechnics with electrical components understood as couples (Roldán- Riejos in preparation) or in civil engineering where a bridge is conceptualized as a person (Roldán-Riejos, 2013). In this paper, the metaphors: WORKING WITH METALS IS COOKING/ TRABAJAR CON METALES ES COCINAR and METALS ARE CULINARY OBJECTS/ LOS METALES SON OBJETOS CULINARIOS are explored. The main aim is to show that the cooking metaphor is widely spread in the metallurgical domain in English and Spanish, although with different nuances in each language due to socio-cultural factors. The method adopted consists of analysing examples taken from the: Bilingual Dictionary of Scientific and Technical Metaphors and Metonymies Spanish- English/English-Spanish, a forthcoming and rigorously documented bilingual dictionary that sums up research on conceptual, linguistic and visual metaphor and metonymy in different areas of engineering (Roldán-Riejos and Molina, 2013). The present paper studies in detail English and Spanish cross-linguistic correspondences related to types of metals and processes. It is suggested that they reflect synesthetic metaphoric mappings. The exploitation of cognitive conceptual metaphor in the ESP classroom is lastly recommended.

Enriching the integration of semantic resources based on WordNet

In this paper we present the enrichment of the Integration of Semantic Resources based in WordNet (ISR-WN Enriched). This new proposal improves the previous one where several semantic resources such as SUMO, WordNet Domains and WordNet Affects were related, adding other semantic resources such as Semantic Classes and SentiWordNet. Firstly, the paper describes the architecture of this proposal explaining the particularities of each integrated resource. After that, we analyze some problems related to the mappings of different versions and how we solve them. Moreover, we show the advantages that this kind of tool can provide to different applications of Natural Language Processing. Related to that question, we can demonstrate that the integration of semantic resources allows acquiring a multidimensional vision in the analysis of natural language.

Análisis del uso de métodos de similitud léxica con conocimiento semántico superficial para mapear la información de enfermería en español

Uno de los problemas actuales en el dominio de la salud es reutilizar y compartir la información clínica entre profesionales, ya que ésta se encuentra escrita usando terminologías específicas. Una posible solución es usar un recurso de conocimiento común sobre el que mapear la información existente. Nuestro objetivo es comprobar si la adición de conocimiento semántico superficial puede mejorar los mapeados establecidos. Para ello experimentamos con un conjunto de etiquetas de NANDA-I y con un conjunto de descripciones de SNOMED-CT en castellano. Los resultados obtenidos en los experimentos muestran que la inclusión de conocimiento semántico superficial mejora significativamente el mapeado léxico entre los dos recursos estudiados.

On the stability of the Motzkin representation of closed convex sets

A set is called Motzkin decomposable when it can be expressed as the Minkowski sum of a compact convex set with a closed convex cone. This paper analyzes the continuity properties of the set-valued mapping associating to each couple (C,D) formed by a compact convex set C and a closed convex cone D its Minkowski sum C + D. The continuity properties of other related mappings are also analyzed.

On the stability of Voronoi cells

Let T be a given subset of ℝ n , whose elements are called sites, and let s∈T. The Voronoi cell of s with respect to T consists of all points closer to s than to any other site. In many real applications, the position of some elements of T is uncertain due to either random external causes or to measurement errors. In this paper we analyze the effect on the Voronoi cell of small changes in s or in a given non-empty set P⊂T\{s}. Two types of perturbations of P are considered, one of them not increasing the cardinality of T. More in detail, the paper provides conditions for the corresponding Voronoi cell mappings to be closed, lower and upper semicontinuous. All the involved conditions are expressed in terms of the data.
