Semantic Neology in the Domain of Videogames in Spanish.

The aim of this paper is to discuss the meaning of five neologisms in the domain of videogames in Spanish: título, aventura, personaje, plataforma, and rol. Our study focuses on a special type of neologism since the Spanish terms we deal with here are not strictly new words; they are what have been called sense neologisms or neosemanticisms, that is, old words taking a new sense in a different domain. These words were identified as new concepts after a process of analysis based on contextual evidence. This study of neology is based on the analysis of a corpus of press articles evaluating videogames published by the Spanish newspaper El País from 1998 to 2008. The analysis of the instances of use of domain specific terms in the corpus revealed that they acquired new senses different to those they have in other domains where they are also used. The paper explains the process of discovering the specialized meaning these words have developed in the domain of videogames and how the analysis of collocational behavior helps in the process of discovering the new sense and in the design of the definition provided. RESUMEN: En este trabajo se presentan cinco neologismos del ámbito del videojuego en español: “título”, “aventura”, “personaje”, “plataforma” y “rol”. Se trata de un tipo especial de neologismo, conocido también como “neologismo semántico” o “neosemanticismo”, ya que son palabras ya existentes en la lengua que adquieren un nuevo significado. Los nuevos significados que adquieren estos términos en el ámbito del videojuego se establecieron tras el análisis del contexto de uso en un corpus periodístico de críticas de videojuegos. Este corpus recoge las críticas de videojuegos publicadas por el periódico El País entre 1998 y 2008. El análisis de los casos de uso de los términos en el corpus de videojuegos reveló que adquirían un nuevo significado diferente al de su uso en otros ámbitos o en el lenguaje general. El artículo describe cada uno de los neologismos y el proceso de análisis contextual que conduce a descubrir el nuevo significado y elaborar su definición.

Embedding logical frameworks in scala

El Framework Lógico de Edimburgo ha demostrado ser una poderosa herramienta en el estudio formal de sistemas deductivos, como por ejemplo lenguajes de programación. Sin embargo su principal implementación, el sistema Twelf, carece de expresividad, obligando al programador a escribir código repetitivo. Este proyecto presenta una manera alternativa de utilizar Twelf: a través de un EDSL (Lenguaje Embebido de Dominio Específico) en Scala que permite representar firmas del Framework Lógico, y apoyándonos en Twelf como backend para la verificación, abrimos la puerta a diversas posibilidades en términos de metaprogramación. El código fuente, así como instrucciones para instalar y configurar, está accesible en https://github.com/akathorn/elfcala. ---ABSTRACT---The Edinburgh Logical Framework has proven to be to be a powerful tool in the formal study of deductive systems, such as programming languages. However, its main implementation, the Twelf system, lacks expressiveness, requiring the programmer to write repetitive code. This project presents an alternative way of using Twelf: by providing a Scala EDSL (Embedded Domain Specific Language) that can encode Logical Framework signatures and relying on Twelf as a backend for the verification, we open the door to different possibilities in terms of metaprogramming.

Generación automática de la configuración de subestaciones eléctricas según el Estándar IEC 61850 a partir de una herramienta de diseño gráfico

La evolución de las redes eléctricas se dirige hacia lo que se conoce como “Smart Grids” o “Redes Eléctricas Inteligentes”. Estas “Smart Grids” se componen de subestaciones eléctricas, que a su vez se componen de unos dispositivos llamados IEDs (Dispositivos Electrónicos Inteligentes – Intelligent Electronic Devices). El diseño de IEDs se encuentra definido en la norma IEC 61850, que especifica además un Lenguaje de Configuración de Subestaciones (Substation Configuration Language SCL) para la definición de la configuración de subestaciones y sus IEDs. Hoy en día, este estándar internacional no sólo se utiliza para diseñar correctamente IEDs y asegurar su interoperabilidad, sino que también se utiliza para el diseño de otros dispositivos de la red eléctrica, como por ejemplo, medidores inteligentes. Sin embargo, aunque existe una tendencia cada vez mayor del uso de este estándar, la comprensión y el manejo del mismo resulta difícil debido al gran volumen de información que lo compone y del nivel de detalle que utiliza, por lo que su uso para el diseño de IEDs se hace tedioso sin la ayuda de un soporte software. Es por ello que, para facilitar la aplicación del estándar IEC 61850 en el diseño de IEDs se han desarrollado herramientas como “Visual SCL”, “SCL Explorer” o “61850 SCLVisual Design Tool”. En concreto, “61850 SCLVisual Design Tool” es una herramienta gráfica para el modelado de subestaciones electricas, generada mediante el uso de los frameworks Eclipse Modeling Framework (EMF) y Epsilon Generative Modeling Technologies (GMT) y desarrollada por el grupo de investigación SYST de la UPM. El objetivo de este proyecto es añadir una nueva funcionalidad a la herramienta “61850 Visual SCL DesignTool”. Esta nueva funcionalidad consiste en la generación automática de un fichero de configuración de subestaciones eléctricas según el estándar IEC 61850 a partir de de una herramienta de diseño gráfico. Este fichero, se denomina SCD (Substation Configuration Description), y se trata de un fichero XML conforme a un esquema XSD (XML Schema Definition) mediante el que se define el lenguaje de configuración de subestaciones SCL del IEC 61850. Para el desarrollo de este proyecto, es necesario el estudio del lenguaje para la configuración de subestaciones SCL, así como del lenguaje gráfico específico de dominio definido por la herramienta “61850 SCLVisual Design Tool”, la estructura de los ficheros SCD, y finalmente, del lenguaje EGL (Epsilon Generation Language) para la transformación y generación automática de código a partir de modelos EMF. ABSTRACT Electrical networks are evolving to “Smart Grids”. Smart Grids are composed of electrical substations that in turn are composed of devices called IEDs (Intelligent Electronic Devices). The design of IEDs is defined by the IEC 61850 standard, which also specifies a Substation Configuration Languaje (SCL) used to define the configuration of substations and their IEDs. Nowadays, this international standard is not only used to design properly IEDs and guarantee their interoperability, but it is also used to design different electrical network devices, such as, smart meters. However, although the use of this standard is growing, its compression as well as its management, is still difficult due to its large volume of information and its level of detail. As a result, designing IEDs becomes a tedious task without a software support. As a consequence of this, in order to make easier the application of the IEC 61850 standard while designing IEDs, some software tools have been developed, such as: “Visual SCL”, “SCL Explorer” or “61850 SCLVisual Design Tool”. In particular, “61850 SCLVisual Design Tool” is a graphical tool used to make electrical substations models, and developed with the Eclipse Modeling Framework (EMF) and Epsilon Generative Modeling Technologies (GMT) by the research group SYST of the UPM. The aim of this project is to add a new functionality to “61850 Visual SCL DesignTool”. This new functionality consists of the automatic code generation of a substation configuration file according to the IEC 61850 standard. This file is called SCD (Substation Configuration Description), and it is a XML file that follows a XSD (XML Schema Definition) that defines the Substation Configuration Language (SCL) of the IEC 61850. In order to develop this project, it is necessary to study the Substation Configuration Language (SCL), the domain-specific graphical languaje defined by the tool “61850 SCLVisual Design Tool”, the structure of a SCD file, and the Epsilon Generation Language (EGL) used for the automatic code generation from EMF models

Neuregulins with an Ig-like domain are essential for mouse myocardial and neuronal development.

Neuregulins are ligands for the erbB family of receptor tyrosine kinases and mediate growth and differentiation of neural crest, muscle, breast cancer, and Schwann cells. Neuregulins contain an epidermal growth factor-like domain located C-terminally to either an Ig-like domain or a cysteine-rich domain specific to the sensory and motor neuron-derived isoform. Here it is shown that elimination of the Ig-like domain-containing neuregulins by homologous recombination results in embryonic lethality associated with a deficiency of ventricular myocardial trabeculation and impairment of cranial ganglion development. The erbB receptors are expressed in myocardial cells and presumably mediate the neuregulin signal originating from endocardial cells. The trigeminal ganglion is reduced in size and lacks projections toward the brain stem and mandible. We conclude that IgL-domain-containing neuregulins play a major role in cardiac and neuronal development.

Phage display selection of ligand residues important for Src homology 3 domain binding specificity.

The Src homology 3 (SH3) domain is a 50-aa modular unit present in many cellular proteins involved in intracellular signal transduction. It functions to direct protein-protein interactions through the recognition of proline-rich motifs on associated proteins. SH3 domains are important regulatory elements that have been demonstrated to specify distinct regulatory pathways important for cell growth, migration, differentiation, and responses to the external milieu. By the use of synthetic peptides, ligands have been shown to consist of a minimum core sequence and to bind to SH3 domains in one of two pseudosymmetrical orientations, class I and class II. The class I sites have the consensus sequence ZP(L/P)PP psi P whereas the class II consensus is PP psi PPZ (where psi is a hydrophobic residue and Z is a SH3 domain-specific residue). We previously showed by M13 phage display that the Src, Fyn, Lyn, and phosphatidylinositol 3-kinase (PI3K) SH3 domains preferred the same class I-type core binding sequence, RPLPP psi P. These results failed to explain the specificity for cellular proteins displayed by SH3 domains in cells. In the current study, class I and class II core ligand sequences were displayed on the surface of bacteriophage M13 with five random residues placed either N- or C-terminal of core ligand residues. These libraries were screened for binding to the Src, Fyn, Lyn, Yes, and PI3K SH3 domains. By this approach, additional ligand residue preferences were identified that can increase the affinity of SH3 peptide ligands at least 20-fold compared with core peptides. The amino acids selected in the flanking sequences were similar for Src, Fyn, and Yes SH3 domains; however, Lyn and PI3K SH3 domains showed distinct binding specificities. These results indicate that residues that flank the core binding sequences shared by many SH3 domains are important determinants of SH3 binding affinity and selectivity.

A protein-binding domain, EH, identified in the receptor tyrosine kinase substrate Eps15 and conserved in evolution.

In this report we structurally and functionally define a binding domain that is involved in protein association and that we have designated EH (for Eps15 homology domain). This domain was identified in the tyrosine kinase substrate Eps15 on the basis of regional conservation with several heterogeneous proteins of yeast and nematode. The EH domain spans about 70 amino acids and shows approximately 60% overall amino acid conservation. We demonstrated the ability of the EH domain to specifically bind cytosolic proteins in normal and malignant cells of mesenchymal, epithelial, and hematopoietic origin. These observations prompted our search for additional EH-containing proteins in mammalian cells. Using an EH domain-specific probe derived from the eps15 cDNA, we cloned and characterized a cDNA encoding an EH-containing protein with overall similarity to Eps15; we designated this protein Eps15r (for Eps15-related). Structural comparison of Eps15 and Eps15r defines a family of signal transducers possessing extensive networking abilities including EH-mediated binding and association with Src homology 3-containing proteins.

Towards moldable development tools

Developers commonly ask detailed and domain-specific questions about the software systems they are developing and maintaining. Integrated development environments (IDEs) form an essential category of tools for developing software that should support software engineering decision making. Unfortunately, rigid and generic IDEs that focus on low-level programming tasks, that promote code rather than data, and that suppress customization, offer limited support for informed decision making during software development. We propose to improve decision making within IDEs by moving from generic to context-aware IDEs through moldable tools. In this paper, we promote the idea of moldable tools, illustrate it with concrete examples, and discuss future research directions.

Independent component analysis for domain independent watermarking

A new principled domain independent watermarking framework is presented. The new approach is based on embedding the message in statistically independent sources of the covertext to mimimise covertext distortion, maximise the information embedding rate and improve the method's robustness against various attacks. Experiments comparing the performance of the new approach, on several standard attacks show the current proposed approach to be competitive with other state of the art domain-specific methods.

SemSearch:a search engine for the semantic web

Existing semantic search tools have been primarily designed to enhance the performance of traditional search technologies but with little support for ordinary end users who are not necessarily familiar with domain specific semantic data, ontologies, or SQL-like query languages. This paper presents SemSearch, a search engine, which pays special attention to this issue by providing several means to hide the complexity of semantic search from end users and thus make it easy to use and effective.

Translating specialised texts:an overview of key factors involved in translator training for specialized translation

Translators wishing to work on translating specialised texts are traditionally recommended to spend much time and effort acquiring specialist knowledge of the domain involved, and for some areas of specialised activity, this is clearly essential. For other types of translation-based, domain-specific of communication, however, it is possible to develop a systematic approach to the task which will allow for the production of target texts which are adequate for purpose, in a range of specialised domains, without necessarily having formal qualifications in those areas. For Esselink (2000) translation agencies, and individual clients, would tend to prefer a subject expert who also happens to have competence in one or more languages over a trained translator with a high degree of translation competence, including the ability to deal with specialised translation tasks. The problem, for the would-be translator, is persuading prospective clients that he or she is capable of this. This paper will offer an overview of the principles used to design training intended to teach trainee translators how to use a systematic approach to specialised translation, in order to extend the range of areas in which they can tackle translation, without compromising quality or reliability. This approach will be described within the context of the functionalist approach developed in particular by Reiss and Vermeer (1984), Nord (1991, 1997) inter alia.

A comparative study of translation strategies applied in dealing with role languages. : A translation analysis of the video game Final Fantasy XIV

Localisation is the process of taking a product and adapting it to fit the culture in question. This usually involves making it both linguistically and culturally appropriate for the target audience. While there are many areas in video game translations where localisation holds a factor, this study will focus on localisation changes in the personalities of fictional characters between the original Japanese version and the English localised version of the video game Final Fantasy XIV: A Realm Reborn and its expansion Heavensward for PC, PS3 and PS4. With this in mind, specific examples are examined using Satoshi Kinsui's work on yakuwarigo, role language as the main framework for this study. Five non-playable characters were profiled and had each of their dialogues transcribed for a comparative analysis. This included the original Japanese text, the officially localised English text and a translation of the original Japanese text done by myself. Each character were also given a short summary and a reasoned speculation on why these localisation changes might have occurred. The result shows that there were instances where some translations had been deliberately adjusted to ensure that the content did not cause any problematic issues to players overseas. This could be reasoned out that some of the Japanese role languages displayed by characters in this game could potentially cause dispute among the western audience. In conclusion, the study shows that localisation can be a difficult process that not only requires a translator's knowledge of the source and target language, but also display some creativity in writing ability to ensure that players will have a comparable experience without causing a rift in the fanbase.

Language-based Techniques for Practical and Trustworthy Secure Multi-party Computations

Secure Multi-party Computation (MPC) enables a set of parties to collaboratively compute, using cryptographic protocols, a function over their private data in a way that the participants do not see each other's data, they only see the final output. Typical MPC examples include statistical computations over joint private data, private set intersection, and auctions. While these applications are examples of monolithic MPC, richer MPC applications move between "normal" (i.e., per-party local) and "secure" (i.e., joint, multi-party secure) modes repeatedly, resulting overall in mixed-mode computations. For example, we might use MPC to implement the role of the dealer in a game of mental poker -- the game will be divided into rounds of local decision-making (e.g. bidding) and joint interaction (e.g. dealing). Mixed-mode computations are also used to improve performance over monolithic secure computations. Starting with the Fairplay project, several MPC frameworks have been proposed in the last decade to help programmers write MPC applications in a high-level language, while the toolchain manages the low-level details. However, these frameworks are either not expressive enough to allow writing mixed-mode applications or lack formal specification, and reasoning capabilities, thereby diminishing the parties' trust in such tools, and the programs written using them. Furthermore, none of the frameworks provides a verified toolchain to run the MPC programs, leaving the potential of security holes that can compromise the privacy of parties' data. This dissertation presents language-based techniques to make MPC more practical and trustworthy. First, it presents the design and implementation of a new MPC Domain Specific Language, called Wysteria, for writing rich mixed-mode MPC applications. Wysteria provides several benefits over previous languages, including a conceptual single thread of control, generic support for more than two parties, high-level abstractions for secret shares, and a fully formalized type system and operational semantics. Using Wysteria, we have implemented several MPC applications, including, for the first time, a card dealing application. The dissertation next presents Wys*, an embedding of Wysteria in F*, a full-featured verification oriented programming language. Wys* improves on Wysteria along three lines: (a) It enables programmers to formally verify the correctness and security properties of their programs. As far as we know, Wys* is the first language to provide verification capabilities for MPC programs. (b) It provides a partially verified toolchain to run MPC programs, and finally (c) It enables the MPC programs to use, with no extra effort, standard language constructs from the host language F*, thereby making it more usable and scalable. Finally, the dissertation develops static analyses that help optimize monolithic MPC programs into mixed-mode MPC programs, while providing similar privacy guarantees as the monolithic versions.

Two case studies on generating administrative process applications with AdminDSL

Some organizations end up reimplementing the same class of business process over and over: an "administrative process", which consists of managing a form through several states and involving various roles in the organization. This results in wasted time that could be dedicated to better understanding the process or dealing with the fine details that are specific to the process. Existing virtual office solutions require specific training and infrastructure andmay result in vendor lock-in. In this paper, we propose using a high-level domain-specific language (AdminDSL) to describe the administrative process and a separate code generator targeting a standard web framework. We have implemented the approach using Xtext, EGL and the Django web framework, and we illustrate it through two case studies: a synthetic examination process which illustrates the architecture of the generated code, and a real-world workplace survey process that identified several future avenues for improvement.

Toward Self-Organising Service Communities

This paper discusses a framework in which catalog service communities are built, linked for interaction, and constantly monitored and adapted over time. A catalog service community (represented as a peer node in a peer-to-peer network) in our system can be viewed as domain specific data integration mediators representing the domain knowledge and the registry information. The query routing among communities is performed to identify a set of data sources that are relevant to answering a given query. The system monitors the interactions between the communities to discover patterns that may lead to restructuring of the network (e.g., irrelevant peers removed, new relationships created, etc.).

Enhancing the Expressiveness of the Bunge-Wand-Weber Ontology

In practical terms, conceptual modeling is at the core of systems analysis and design. The plurality of modeling methods available has however been regarded as detrimental, and as a strong indication that a common view or theoretical grounding of modeling is wanting. This theoretical foundation must universally address all potential matters to be represented in a model, which consequently suggested ontology as the point of departure for theory development. The Bunge–Wand–Weber (BWW) ontology has become a widely accepted modeling theory. Its application has simultaneously led to the recognition that, although suitable as a meta-model, the BWW ontology needs to be enhanced regarding its expressiveness in empirical domains. In this paper, a first step in this direction has been made by revisiting BUNGE’s ontology, and by proposing the integration of a “hierarchy of systems” in the BWW ontology for accommodating domain specific conceptualizations.
