Tecnhiques for sentiment analysis in Twitter: Supervised Learning and SentiStrength
2017
[EN] Sentiment analysis on Twitter offers possibilities of great interest to evaluate the currents of opinion disseminated through this medium. The huge volumes of texts require tools able to automatically process these messages without losing reliability. This paper describes two different types of approaching this problem. The first strategy is based on Supervised Learning processes, developed in the field of artificial intelligence. Its application requires some tools from natural language processing along with a classifed corpus as a starting point. The second approach is based on polarity dictionaries. SentiStrength tool is located in this line. It is increasingly applied to studies of…
Incorporando dispositivos de radio definida por software en la materia de Comunicaciones Digitales: del grupo piloto a la gran clase
2020
La innovación educativa es un proceso que se extiende más allá de un curso académico. En su desarrollo se distinguen las etapas de planificación, implementación, evaluación y realimentación, para identificar aspectos susceptibles de mejora. En esta contribución presentamos el trabajo desarrollado en los dos últimos cursos en la asignatura Teoría de la Comunicación (materia de Comunicaciones Digitales), Grado en Ingeniería Telemática, de la Universitat de València. Concretamente, se incorporan dispositivos de radio definida por software en los laboratorios como herramienta para conseguir unas prácticas más realistas. El artículo describe el proceso de adaptación de una sesión de laboratorio, qu…
Estado de la investigación sobre la colaboración en Entornos Virtuales de Aprendizaje
2019
El aprendizaje colaborativo posee una tradición teórica y práctica amplia en la educación general, como en la educación superior. No obstante, la actividad de coordinación entre personas que buscan aprender no es sencilla de gestionar. Esta complejidad aumenta cuando entre la actividad colaborativa surge un nuevo componente, la tecnología. ¿Qué se ha avanzado sobre el aprendizaje colaborativo mediado tecnológicamente? Este trabajo tiene como objetivo analizar el estado de la investigación sobre aprendizaje colaborativo en Educación Superior en los Entornos Virtuales de Aprendizaje (EVA). Para ello se realiza un análisis bibliométrico de las publicaciones indexadas de la base de datos SCOPUS…
Las competencias básicas en la nueva generación de estudiantes universitarios: Una experiencia de Innovación.
2017
[EN] This contribution presents an innovative teaching experience dedicated to developing core competencies in the university student by activating educational practices and evaluation procedures that seek to promote and maximize various competitions. This experiencie has been implemented in different degrees of the University of Valencia during the academic years 2011-12, 2012-13, 2013-14 and 2014-15. Participating in the study 1285 students through accidental sampling accessibility. After developing a survey methodology based on descriptive-exploratory analyzes data collected allow us to know what is the degree of control perceived by university students around the following core competen…
Arc routing problems: A review of the past, present, and future
2020
[EN] Arc routing problems (ARPs) are defined and introduced. Following a brief history of developments in this area of research, different types of ARPs are described that are currently relevant for study. In addition, particular features of ARPs that are important from a theoretical or practical point of view are discussed. A section on applications describes some of the changes that have occurred from early applications of ARP models to the present day and points the way to emerging topics for study. A final section provides information on libraries and instance repositories for ARPs. The review concludes with some perspectives on future research developments and opportunities for emergin…
Facing the face – the construction of the frontal face in prehistoric and ancient two- and three-dimensional images
2020
Interpersonal communication depends to a large extent on the human face, with its many sensory organs, easily recognizable features and expression capacities. This is clearly evidenced by the abund...
Special Issue “Smart Urban Lighting Systems”
2020
The design and operation of multifunctional infrastructures for public lighting as well as their impact on the urban environment and citizens’ life is today of great interest. The cost of energy for public lighting is often an issue for the budget of municipalities. Furthermore, researchers’ and designers’ attention is increasingly focused on aspects of public lighting not directly valuable through economic factors. Starting from the “quality” of the light environment, looking at citizens’ visual comfort, the light has to be considered as an instrument to improve the urban context and objects therein (including buildings). Indeed, urban degradation (lack of infrastructures, maintenance, ser…
Technologies of Re-familization
2019
In this chapter, the notion of re-familization is introduced, to allow for a better grasp of the cohesive impact of digital technologies in the context of extended and geographically distributed families. In the field of social policy, the notion of re-familization implies a reversal of the politics of de-familization that once was the hallmark of the golden-era welfare state. The argument is made that family-initiated uses of digital media and communication technology in response to (older) family members’ daily help and care needs resonate well with the idea behind re-familization. In conclusion, the chapter presents several ways in which re-familization manifests itself in the everyday l…
Electronic Mail as a Forum for Argumentative Interaction in Higher Education Studies
1998
This article reports a study in which thirty-one undergraduate students practiced academic argumentation by electronic mail (e-mail). In the two “tutorled” e-mail study groups the discussion topics were selected by the tutor, while in the two self-directed “student-led” groups selection was by the students. The quantity and quality of student-student interaction, and the factors associated with this were investigated. The results indicated that 42 percent of the students' messages (n = 441) were interactive in nature, indicating at least one reference to fellow students' messages. When difficult contents were addressed, interaction in the tutor-led groups was more common than in the studen…
Argumentative Knowledge Construction in Online Learning Environments in and across Different Cultures: A Collaboration Script Perspective
2007
In recent years, information and communication technology has established new opportunities to participate in online learning environments around the globe. These opportunities include the dissemination of specific online learning environments as well as opportunities for learners to connect to online learning environments in distant locations. These dissemination and distance learning scenarios create potential challenges, however, in terms of the cultural differences in the internal scripts that learners of different cultures bring to these environments. This article considers these issues and challenges specifically for online environments focusing on argumentative knowledge constructio…
