Towards automatic tweet generation: A comparative study from the text summarization perspective in the journalism genre

In recent years, Twitter has become one of the most important microblogging services of the Web 2.0. Among the possible uses it allows, it can be employed for communicating and broadcasting information in real time. The goal of this research is to analyze the task of automatic tweet generation from a text summarization perspective in the context of the journalism genre. To achieve this, different state-of-the-art summarizers are selected and employed for producing multi-lingual tweets in two languages (English and Spanish). A wide experimental framework is proposed, comprising the creation of a new corpus, the generation of the automatic tweets, and their assessment through a quantitative and a qualitative evaluation, where informativeness, indicativeness and interest are key criteria that should be ensured in the proposed context. From the results obtained, it was observed that although the original tweets were considered as model tweets with respect to their informativeness, they were not among the most interesting ones from a human viewpoint. Therefore, relying only on these tweets may not be the ideal way to communicate news through Twitter, especially if a more personalized and catchy way of reporting news wants to be performed. In contrast, we showed that recent text summarization techniques may be more appropriate, reflecting a balance between indicativeness and interest, even if their content was different from the tweets delivered by the news providers.

Redes sociales de lectura: del libro de caras a la LIJ 2.0

Entre las múltiples posibilidades que nos ofrecen los distintos servicios de redes sociales y microblogging, algunos objetivos fundamentales para su uso didáctico pueden ser el fomento de la lectura y el desarrollo de la competencia lectoliteraria. Contrariamente a lo que muchas voces plantean, que las ven como una distracción frente a la lectura tradicional, las redes sociales son un espacio de conversación y lectura donde, con dinámicas adecuadas, se puede trabajar la comprensión lectora desde muy distintas perspectivas, siendo un espacio central de lo que se ha definido como LIJ 2.0 (Literatura y Lectura Infantil y Juvenil en la Web Social).

New Approaches for Teaching Soil and Rock Mechanics Using Information and Communication Technologies

Soil and rock mechanics are disciplines with a strong conceptual and methodological basis. Initially, when engineering students study these subjects, they have to understand new theoretical phenomena, which are explained through mathematical and/or physical laws (e.g. consolidation process, water flow through a porous media). In addition to the study of these phenomena, students have to learn how to carry out estimations of soil and rock parameters in laboratories according to standard tests. Nowadays, information and communication technologies (ICTs) provide a unique opportunity to improve the learning process of students studying the aforementioned subjects. In this paper, we describe our experience of the incorporation of ICTs into the classical teaching-learning process of soil and rock mechanics and explain in detail how we have successfully developed various initiatives which, in summary, are: (a) implementation of an online social networking and microblogging service (using Twitter) for gradually sending key concepts to students throughout the semester (gradual learning); (b) detailed online virtual laboratory tests for a delocalized development of lab practices (self-learning); (c) integration of different complementary learning resources (e.g. videos, free software, technical regulations, etc.) using an open webpage. The complementary use to the classical teaching-learning process of these ICT resources has been highly satisfactory for students, who have positively evaluated this new approach.

Lectura social y LIJ 2.0 en la universidad. Aplicaciones y redes sociales de lectura

Dentro del desarrollo de nuevos conceptos pedagógicos como las Tecnologías del Aprendizaje y el Conocimiento (TAC) y el Mobile Learning han aparecido algunos aspectos principales como la Lectura Social y la LIJ 2.0 fundamentales para la didáctica de la lengua y la literatura en entornos digitales. Entre las múltiples posibilidades que nos ofrecen los distintos servicios de redes sociales y microblogging, algunos objetivos para su uso didáctico pueden ser el fomento de la lectura y el desarrollo de la competencia lectoliteraria. Las redes sociales pueden ser un espacio de conversación y lectura donde, con dinámicas adecuadas, se trabaje la comprensión lectora desde muy distintas perspectivas. En el siguiente trabajo se hará una revisión de las distintas herramientas, desde los espacios más generalistas como Facebook o los clubes de lectura a través de servicios como Twitter, hasta llegar a aplicaciones y redes sociales específicas centradas en la literatura, como Aldiko, Wattpad, Ibooks, Anobii, Goodreads o Entrelectores, haciendo una descripción de las distintas posibilidades para la formación del alumnado y la promoción de la lectura.
