Análisis comparativo de herramientas para marcadores sociales

Presentamos en el Congreso ISKO 2011, X Congreso del Capítulo Español de ISKO, que se celebra en la Fac. de Humanidades de la Universidad de La Coruña, el paper Tramullas, J., Garrido, P y Sáchez Casabón, A.I., Análisis comparativo de herramientas para marcadores sociales (Comparative analysis of social bookmarking tools.)

Resumen: Los marcadores sociales son sistemas de etiquetado social de enlaces que han sido ampliamente utilizados en bibliotecas y servicios de información. Sin embargo, no se ha llevado a cabo un estudio del modelo de gestión de información subyacente, ni de las funcionalidades técnicas necesarias para cumplir con los requerimientos del modelo. Este trabajo delinea un modelo genérico basado en la detección de funcionalidades, y lo aplica sobre ocho servicios de marcados sociales. Los resultados obtenidos permiten afirmar que las prestaciones de los servicios no cubren todas las funcionalidades del modelo genérico, y que la capa de prestaciones sociales es insuficiente.

Palabras clave: marcadores sociales, evaluación de herramientas, etiquetado, web 2.0

Abstract: Social bookmarks are systems of social labeling of links that have been widely used in libraries and information services. However, there hasn’t been a study of the information management model underlying social bookmarking tools, or technical capabilities necessary to meet the requirements of the model. This paper outlines a generic model based on the detection of features, and applies it on eight social bookmarking services. The results confirm that the performance of the services do not cover all features of the generic model, and the layer of social services is inadequate.

Keywords: Social bookmarking, tool evaluation, web 2.0, tagging.

HyBook: A LifeLong Learning Management System in Higher Education

Presentamos en la II Conferencia Internacional en Fomento e Innovación con Nuevas Tecnologías en la Docencia de Ingeniería FINTDI 2011 el short paper/poster Garrido, P., Tramullas, J., Martínez, F. J., Porcel, B. “HyBook: A LifeLong Learning Management System in Higher Education.”

Abstract: E-books are not only becoming an important part in the development of digital library collections, but also in the management of lifelong learning systems. The project which we hereby detail has been partly dedicated to this particular task. Thanks to the End of Course compulsory subject, an ad-hoc tool has been designed and implemented with the objective of improving the management of a lifelong learning organization system. A multidisciplinary group including Area and Maintenance Staff as well as Research/Teaching staff was created for the purpose of finally obtaining a tool which incorporates a repository of hybrid information by using descriptive techniques such as FOAF (Friend of a Friend Project) and the Topic Maps paradigm. As a use case, it has been tested at the Instituto de Ciencias de la Educación (ICE) of the University of Zaragoza (UZ).

Keywords: Topic Maps; XTM; FOAF; lifelong learning, e-book

Jornada de Calidad de Revistas de Ciencias Sociales CRECS 2011

El 3 de mayo se celebró la Jornada de Calidad en Revistas de Ciencias Sociales CRECS, el auditorio de la Fac. de Comunicación Blanquerna (Univ. Ramón Llul). El evento sirvió para celebrar el 20 aniversario de la revista El Profesional de la Información, el EPI de siempre, y para presentar el Anuario ThinkEPI 2011. Aparte de felicitar a los protagonistas de ambas hechos, lo interesante, y verdaderamente remarcable, es que el evento sirvió para reunir a especialistas en diferentes aspectos de evaluación y de edición de revistas científicas, que expusieron, con una claridad notable, problemas, perspectivas, proyectos y tesituras actuales.

Weblog publishing behaviour of librarianship and information science students: a case study

En el último número de Information Research publican nuestro trabajo Tramullas, J. & Garrido, P. (2011). Weblog publishing behaviour of librarianship and information science students: a case studyInformation Research, 16, 1, paper 456.

Introduction. The ‘blogosphere’ is a space with digital information in which social networks form that offer countless application possibilities. In this technology-mediated context, it is feasible to study the performance and approaches of production, diffusion, relationship and use of information from different perspectives..
Method. Quantitative data were obtained through the regular examination of the blogs maintained by students and qualitative data were obtained from reports by the students and self-assessment questionnaires.
Analysis. Simple counts of quantitative data were obtained, without further statistical analysis. The qualitative data were reviewed for insights into the motivations of students.
Results. Given a free choice, most students adopted the Blogger platform for their blogs. Most blogs consisted of content reported from elsewhere and were not continued by the students following the end of the exercise.
Conclusions. Students adopted an instrumental approach to the exercise, doing enough to complete the course requirements but not being sufficiently engaged to continue their blogs. Preliminary work based on basic competences is necessary in both collaboration processes and Web 2.0 technology to obtain satisfactory results in the use of Weblogs as teaching and learning tools.

Se trata de una revisión mejorada y ajustada del texto original que presentamos al Information Seeking in Context 2010. Damos las gracias al Prof. Tom Wilson por su trabajo de edición.

Clásicos: What is a document? Buckland, 1997.

Revisando hace unos días lecturas para una ponencia, encontré de nuevo un texto ya clásico de Michael Buckland, en el cual, hace una docena de años, reflexionaba sobre el concepto de documento. La referencia completa es Buckland, Michael (1997): “What is a document?” Journal of the American Society of Information Science 48, 9: 804-809.

Application of semantic tagging to generate superimposed information on a digital encyclopedia

Hoy presentamos en el Fourth Metadata and Semantics Research Conference (MTSR 2010), que se celebra en la Univ. de Alcalá de Henares, el trabajo Garrido, P. Tramullas, J. y Martínez, F.J., Application of semantic tagging to generate superimposed information on a digital encyclopedia. Se publica en Sánchez-Alonso, S. and Athanasiadis, I. (eds.) Metadata and Semantic Research. 4th International Conference MTSR 2010, Communications in Computer and Information Science 108. Heidelberg: Springer, 2010, 84-94.

Abstract. We can find in the literature several works regarding the automatic or semi-automatic processing of textual documents with historic information using free software technologies. However, more research work is needed to integrate the analysis of the context and provide coverage to the peculiarities of the Spanish language from a semantic point of view. This research work proposes a novel knowledge-based strategy based on combining subject-centric computing, a topic-oriented approach, and superimposed information. It subsequent combination with artificial intelligence techniques led to an automatic analysis after implementing a made-to-measure interpreted algorithm which, in turn, produced a good number of associations and events with 90% reliability.

Keywords: Topic Maps, DITA, XTM, electronic encyclopedia, automatic processing, artificial intelligence, superimposed information
