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.

Analysis of the behavior of librarianship and information science students in weblogs services

Presentamos en la sesión de short papers del Information Seek in Context (ISIC) 2010 el trabajo J. Tramullas y P. Garrido Analysis of the behavior of librarianship and information science students in weblogs services. En el mismo revisamos las pautas de comportamiento informacional de estudiantes de Información y Documentación, el marco del desarrollo de proyectos de blog como herramientas de aprendizaje y evaluación.

Abstract: Blogosphere is a space with digital information in which social networks form that offer countless application possibilities. In this technology-mediated context, it is technologically feasible to study the performance and approaches of production, diffusion, relationship and use of information from different perspectives. This work analyses information management approaches within a series of librarianship and information science students’ weblogs by comparing two consecutive academic courses for the purpose of verifying whether students’ performance matches a specific user profile or offers characteristics of its own.

Free Traceability Management Using RFID and Topic Maps

Presentamos en la 4th European Conference on Information Management and Evaluation (Lisboa, Septiembre 2010) el trabajo Garrido, P., Naranjo, F, Tramullas, J. et alii, “Free Traceability Management using RFID and Topic Maps.” Este trabajo está relacionado con otro anterior en el que abordábamos el uso de etiquetado semántico para la gestión de información, y por el que recibimos un premio en un congreso. Esta conferencia está considerada como “Core C”, dentro de los listados de factor de impacto.

Abstract: The Governing Board of the Protected Designation of Origin “Ham from Teruel” is involved in the development of a system that guarantees the traceability of the pig’s legs. This initiative is innovative since there is no other Governing Board which has such a system to respond to unforeseen circumstances occurred at the slaughterhouse unit. To accomplish the requirements, three different strategies have been followed: (i) RadioFrequency Identification (RFID) technology, which uses a wireless link to transfer data in a fast and easy way – just placing the tag within the communication range of the reader – between read/write access points strategically placed in the slaughter chain and tags attached to every pig’s leg, (ii) the security of the traceability system, that provides evidence that all the controls in a production process have been activated. This enables the client to quickly verify that all the products have correctly passed through the production cycle with the guarantee of trust provided under the responsibility of the signer, and (iii) a free documentary management system (DMS), which is necessary to correctly manage the information collected during the slaughtering process. This paper is focused on the third strategy. To develop the documentary management system, we use the ISO 13250 which defines the Topic Maps paradigm, and its XTM specification. The combination of both technologies (RFID and XTM) in the traceability system offers several advantages to manage the online information in real-time.

Aplicaciones de software educativo para el diseño de sistemas de información empresarial

Hoy presentamos en el XI Simposio Nacional de Tecnologías de la Información y las Comunicaciones en la Educación, SINTICE 2010, que se celebra en el marco del Congreso Español de Informática, CEDI, (Valencia, 2010) el trabajo Garrido, P., Hernández, L., Martínez, F.J., Naranjo, F., Tramullas, J., Plaza, I, “Aplicaciones de Software Educativo para el Diseño de Sistemas de Información Empresarial.”

Resumen: La presente contribución tiene como objetivo presentar una experiencia que se está llevando a cabo en la Universidad de Zaragoza con la que se pretende fomentar la Informática Educativa y promover la colaboración de los sectores educativo, público y privado de la sociedad mediante el acercamiento al software educativo desarrollado en el ámbito universitario que pueda resultar de utilidad en el sector empresarial. El proyecto se encuentra en la actualidad en fase de desarrollo, pero los resultados del mismo están siendo muy satisfactorios, gracias tanto a la transferencia tecnológica directa (universidad-empresa), como a la transferencia tecnológica inversa (empresa-universidad).

Abstract: The present contribution aims to present an experience that is taking place at the University of Zaragoza which aims to promote Computer Science Education and promote the collaboration of education sectors, public and private sectors of society through the approach to educational software developed in the university that may be useful in the business sector. The project is currently under development, but the results of it are still very successful, thanks to both direct technology transfer (universities to companies) as a reverse technology transfer (company to university).
