“…Finally, it is important the definition of search criteria based on metadata defined by digital resources to perform the implementation of visualization techniques. Search criteria based on metadata have been considered in several studies in the field of digital libraries [25]. For example, in the Europeana digital library [36], some search criteria are defined such as: subject, language, content provider, digital resource format (image, video, audio, etc.).…”

Repositories are important infrastructures which allow the dissemination of large collections of digital resources hosted in museums, libraries, academic institutions or specialized documentation centers. However, there are nowadays several limitations associated with irrelevant search results based on a knowledge area. Some studies have highlighted the major role of information visualization strategies based on Simple Knowledge Organization Systems (SKOS) so as to mitigate such difficulties. The main goal of this article is to present recommendations using information visualization based on SKOS for the development of navigational search interfaces in digital repositories focused on learning process. We use card sorting as methodology in order to obtain qualitative results in our study. As preliminary results we found that taxonomies in visual search engines improve the access to large collections of digital resources based on SKOS, but it depends on the design of taxonomy concepts defined in digital repositories. Finally, it is recommended that the creators of repositories focus their efforts on define levels of relationship and partnership between digital resources using knowledge representation structures like thesauri or ontologies; work with usable visualization interfaces like tree, radial or icicle; and link relevant metadata fields with the navigation structure.

“…One of the greatest challenges that specialized libraries like Europeana face is how to best facilitate access to digital resources. Therefore, there is a need to define appropriate search strategies reflected in the definition of knowledge classification schemes (ontologies and thesaurus), metadata quality design and development of flexible visual search interfaces, in order to improve the conditions of access to digital resources (Gaona-García et al , 2017, 2016; Gaona-García, Martín-Moncunill, Sánchez-Alonso, and Fermoso García, 2014; Gaona-García, Sánchez, and Montenegro, 2014). These needs represent, within an educational scenario, the necessary conditions for creating a collaborative work environment in order to facilitate search processes relevant to find educational material, and categorically cover knowledge areas of interest.…”

Purpose The purpose of this paper is to assess whether Europeana can be really seen as the new “Library of Alexandria” for digital resources from the perspective of teachers, academics and researchers that might want to retrieve and reuse those resources for learning purposes. Design/methodology/approach The authors define a systematic method for studying Europeana digital resources and their potential for reuse in e-learning environments. To achieve this, the authors explore the coverage of digital resources when searching information about a specific area. The paper studies the relevance of the results (thematic coverage) provided by queries targeting the resources’ metadata elements defined by the EDM Europeana model. All the data collected for this study from Europeana digital resources are the result of four explorations since 2012-2016. Findings The autors found that Europeana as a digital library has good levels of coverage of digital resources for those terms in the AAT thesaurus explored (terms from the “Styles and Periods” subset). This subset was selected as an example of faceted search given that it is a common search topic in the academic environment. However, it is important to remark the use of common vocabulary words provided by participants in order to obtain relevant results of search based on specific knowledge areas defined by AAT terms. Research limitations/implications This research used a relatively small sample size of resources which may not be representative of the general size of Europeana digital resources. However, the results are illustrative as they are based on a specific knowledge area of AAT (118 terms) which contains very common topics used in high school courses by students and teachers in the field of art and cultural heritage. The study also aspires to provide a systematic method for conducting future studies in other knowledge areas. Originality/value The coverage study aims to analyze if Europeana is a digital library that teachers could use for the development of learning objects in specific knowledge areas, through the reuse of free/open access digital resources.

“…Sin embargo, muchos de los materiales allí consignados carecen de actualizaciones o enfoques pedagógicos para su uso a partir de estilos de aprendizajes. Algunos de los factores asociados a este problema son: 1) el desconocimiento de herramientas para creación de recursos digitales con un propósito definido, 2) falta de lineamiento institucional para el desarrollo de contenidos digitales de calidad, 3) mecanismos de búsqueda poco efectivos para la localización de material relevante [1]- [5].…”

Modelo ontológico basado en web of confianza para analizar el uso de recursos en entorno de aprendizajeResumen-Los recursos utilizados dentro de un entorno de aprendizaje virtual son de vital importancia para el desarrollo de actividades y formación de estudiantes. Actualmente existe una gran variedad de recursos dentro de plataformas virtuales de aprendizaje; sin embargo, se desconoce si todos estos recursos pueden ser utilizados por todos los participantes dentro de un proceso de formación de acuerdo con sus estilos de aprendizaje. El siguiente artículo tiene como propósito definir un modelo ontológico que facilite el análisis estructural del uso de herramientas como blogs, foros, chats, así como diferentes tipos de objetos de aprendizaje, dentro de plataformas Learning Content Management System. Para facilitar el estudio se utilizó Pajek como herramienta de análisis de redes sociales. Se pretende con este modelo analizar el comportamiento de participantes dentro de plataformas virtuales, así como la interacción que ellos tienen con las herramientas y contenidos dentro de una plataforma de aprendizaje LCMS.Palabras clave-Análisis de redes sociales, e-learning, methontology, ontologías, pajek.Abstract-Resources used in a virtual learning environment are of crucial importance for the development of activities and training students. There is currently a wide range of resources within virtual learning platforms, however is unknown if all of these resources can be used by all participants in a training process according to their learning styles. The following article aims to define an ontological model which promotes structural analysis using tools such as blogs, forums, chats, as well as different types of learning objects within Learning Content Management System platforms.
