Computational approaches to subjectivity and sentiment analysis: Present and envisaged methods and applications

Recent years have witnessed a surge of interest in computational methods for affect, ranging from opinion mining, to subjectivity detection, to sentiment and emotion analysis. This article presents a brief overview of the latest trends in the field and describes the manner in which the articles contained in the special issue contribute to the advancement of the area. Finally, we comment on the current challenges and envisaged developments of the subjectivity and sentiment analysis fields, as well as their application to other Natural Language Processing tasks and related domains.

Deporte e igualdad: las voces de las deportistas de élite

El objetivo de esta investigación ha sido analizar y valorar las percepciones de las deportistas de élite ante su insuficiente presencia en el deporte. La metodología utilizada permite examinar e interpretar los pensamientos y creencias de una cohorte de deportistas de alto rendimiento. El instrumento utilizado para el tratamiento de los datos ha sido el programa informático AQUAD 7. En este estudio se abordan diferentes modalidades de relación de las participantes (el balonmano como deporte colectivo, el atletismo como individual y la lucha judo como una competición entre dos individuos). Los resultados muestran que las deportistas perciben situaciones de discriminación de género y ausencias de igualdad de oportunidades en su desarrollo profesional. Las conclusiones de este estudio aconsejan proponer un cambio en las políticas tendentes a la equiparación efectiva en la carrera deportiva de las mujeres.

imaxin|software: PLN aplicada a la mejora de la comunicación multilingüe de empresas e instituciones

imaxin|software es una empresa creada en 1997 por cuatro titulados en ingeniería informática cuyo objetivo ha sido el de desarrollar videojuegos multimedia educativos y procesamiento del lenguaje natural multilingüe. 17 años más tarde, hemos desarrollado recursos, herramientas y aplicaciones multilingües de referencia para diferentes lenguas: Portugués (Galicia, Portugal, Brasil, etc.), Español (España, Argentina, México, etc.), Inglés, Catalán y Francés. En este artículo haremos una descripción de aquellos principales hitos en relación a la incorporación de estas tecnologías PLN al sector industrial e institucional.

An Ecological Model for Predicting Behaviour of Mediterranean Shrublands

In order to build dynamic models for prediction and management of degraded Mediterranean forest areas was necessary to build MARIOLA model, which is a calculation computer program. This model includes the following subprograms. 1) bioshrub program, which calculates total, green and woody shrubs biomass and it establishes the time differences to calculate the growth. 2) selego program, which builds the flow equations from the experimental data. It is based on advanced procedures of statistical multiple regression. 3) VEGETATION program, which solves the state equations with Euler or Runge-Kutta integration methods. Each one of these subprograms can act as independent or as linked programs.

An overview of the Applications of Natural Language to Information Systems

This introduction provides an overview of the state-of-the-art technology in Applications of Natural Language to Information Systems. Specifically, we analyze the need for such technologies to successfully address the new challenges of modern information systems, in which the exploitation of the Web as a main data source on business systems becomes a key requirement. It will also discuss the reasons why Human Language Technologies themselves have shifted their focus onto new areas of interest very directly linked to the development of technology for the treatment and understanding of Web 2.0. These new technologies are expected to be future interfaces for the new information systems to come. Moreover, we will review current topics of interest to this research community, and will present the selection of manuscripts that have been chosen by the program committee of the NLDB 2011 conference as representative cornerstone research works, especially highlighting their contribution to the advancement of such technologies.

Evaluation of the Implementation of CLIL (Content and Language Integrated Learning) Methodology in the Didactics of the English Language in Preschool Education Course Taught in the Preschool Education Teacher Undergraduate Program at the University of Alicante

Although it is known that the Spanish current Educative System promotes using the Communicate Approach to teach foreign languages in schools, other recently designed approaches are also used to help students improve their skills when communicating in a foreign language. One of these approaches is Content and Language Integrated Learning, also known as CLIL, which is used to teach content courses using the English language as the language of instruction. This approach improves the students’ skills in English as the same time as they learn content from other areas. The goal of this thesis is to present a research project carried out at the University of Alicante during the academic year 2011-2012. With this research we obtained results that provide quantitative and qualitative data which explains how the use of the CLIL methodology affects the English level of students in the “Didactics of the English Language in Preschool Education” course in Preschool Education Teacher Undergraduate Program as students acquire the contents of the course.
