Linked Data in Education: A Survey and a Synthesis of Actual Research and Future Challenges
Peer reviewed Peer reviewed
Direct linkDirect link
Pereira, Crystiam Kelle; Siqueira, Sean Wolfgand Matsui; Nunes, Bernardo Pereira; Dietze, Stefan – IEEE Transactions on Learning Technologies, 2018
Linked Data principles and technologies are being investigated in various areas. In the Educational context, many studies are using Linked Data trying to solve problems of interoperability of educational data and resources, enriching educational content, and personalizing and recommending educational content and practices. This article presents a…

Taibi, Davide; Chawla, Saniya; Dietze, Stefan; Marenzi, Ivana; Fetahu, Besnik – British Journal of Educational Technology, 2015
In this paper, we present the TED Talks dataset which exposes all metadata and the actual transcripts of available TED talks as structured Linked Data. The TED talks collection is composed of more than 1800 talks, along with 35?000 transcripts in over 30 languages, related to a wide range of topics. In this regard, TED talks metadata available in…

Dietze, Stefan; Taibi, Davide; Yu, Hong Qing; Dovrolis, Nikolas – British Journal of Educational Technology, 2015
Reusable educational resources became increasingly important for enhancing learning and teaching experiences, particularly in the medical domain where resources are particularly expensive to produce. While interoperability across educational resources metadata repositories is yet limited to the heterogeneity of metadata standards and interface…

Dietze, Stefan; Sanchez-Alonso, Salvador; Ebner, Hannes; Yu, Hong Qing; Giordano, Daniela; Marenzi, Ivana; Nunes, Bernardo Pereira – Program: Electronic Library and Information Systems, 2013
Purpose: Research in the area of technology-enhanced learning (TEL) throughout the last decade has largely focused on sharing and reusing educational resources and data. This effort has led to a fragmented landscape of competing metadata schemas, or interface mechanisms. More recently, semantic technologies were taken into account to improve…

Supporting Interoperability and Context-Awareness in E-Learning through Situation-Driven Learning Processes
Peer reviewed Peer reviewed
Direct linkDirect link
Dietze, Stefan; Gugliotta, Alessio; Domingue, John – International Journal of Distance Education Technologies, 2009
Current E-Learning technologies primarily follow a data and metadata-centric paradigm by providing the learner with composite content containing the learning resources and the learning process description, usually based on specific metadata standards such as ADL SCORM or IMS Learning Design. Due to the design-time binding of learning resources,…

Dietze, Stefan; Gugliotta, Alessio; Domingue, John – Journal of Interactive Media in Education, 2007
IMS Learning Design (IMS-LD) is a promising technology aimed at supporting learning processes. IMS-LD packages contain the learning process metadata as well as the learning resources. However, the allocation of resources--whether data or services--within the learning design is done manually at design-time on the basis of the subjective appraisals…
