Workshop format

challenge_logoThe LinkedUp Vidi Competition was open to anyone around the world who enjoys mashing up data or creating new and interesting tools and applications.

We specifically targeted researchers and practitioners from both the eLearning area as well as the semantic technologies field. Participants were invited to submit their Web application, app, analysis toolkit, documented API or any other tool that connects, exploits or analyses open or linked data and that addresses real educational needs. The LinkedUp project have compiled a catalogue of data sets as a starting point, and have offered several opportunities for support and guidance. Full details of the Vidi competition can be found on the LinkedUp Challenge Website.

The deadline for Vidi has now closed and we have shortlisted 9 exciting submissions. Some have followed our focused tracks, so designing solutions to a particular education problem (such as how you navigate open education courses and related resources), and others have followed our open tracks.

Come along to the LinkedUp Vidi Competition Presentations and Awards to hear about the  best-ranked submissions and their potential use in the education community.

We will have the following half-day schedule:

  • Welcome and Panel Discussion on Linked Data for Open Education
  • Keynote from Dr. Harald Sack, Hasso-Plattner-Institut für Softwaresystemtechnik GmbH
  • Presentation of the Vidi Competition submissions (15 minutes each, includ
ing questions)
  • Demo and poster session, including audience voting 
We plan to organize, in cooperation with the ESWC Challenge organizers, an event at the main conference, during which the winning submissions are announced and presented.

A more detailed schedule is available online.

Title: Semantic Analysis of Video Data to Enable Exploratory Search

Abstract: Video Data has become a first class citizen of the Web. Also in the area of eLearning lecture recordings in combination with massive open online courses have become rather popular and their numbers are constantly growing. To find the appropriate video content according to the user’s information needs and to make well suited content based recommendations for videos still is an issue of ongoing research. Semantic technologies combined with state-of-the-art video analysis, as e.g. speech to text, video ocr, and visual concept detection, enable pinpoint access to video data and clear the path for content based recommender systems. Based on time-based semantically annotated video data new ways become feasible of accessing video in an exploratory way to enhance user experience.

Prototypes and apps to be presented:

  • Fabrizio Celli – AGRIS – exploiting bibliographic records to create rich Linked Open Data page (remote presentation)
  • Ricardo Kawase, Ujwal Gadiraju and Patrick Siehndel DBLPXplorer: Interactive Graphical Interfaces for the Computer Science Bibliography
  • Michel Visser, Simone Potenza and Romee Houben – Konnektid – Social Learning Anytime, Anywhere
  • Jianliang Chen, Yuting Liu, Dipanwita Maulik, Linda Xu, Hao Zhang, Craig A. Knoblock, Pedro Szekely and Miel Vander Sande – LODStories: Learning About Art by Building Multimedia Stories
  • Dor Garbash, Eyal Rotbart, William Zeng, Brendan Fong, Erik Edstrom, Jacob Cole, Calvin Fong, Yael Ben Dov –
  • Pat Lockley – Solvonauts : an open educational search engine (remote presentation)
  • Harshil Parikh, Jaimin Patel, Benjamin Farahmand and Rachana Pandey – TuvaLabs – Data Literacy Skills for a Brighter Future
  • Leonardo Lezcano, Michel Triana, Bridget Maher, Pat Henn, Carola Orrego, Lina Stieger, Hanna Schroeder, Susanne Druener, Sasa Sopka and Marcus Specht – The electronic Discharge Letter (eDL) mobile app
  • Vyacheslav Tykhonov – Visualization of Labour Conflicts in the Netherlands for last 700 years

The Semantic Web has redefined itself throughout the last years as a Web of ‘Linked Data’, by establishing principles that support sharing of large datasets on the Web together with a technology stack – fundamentally based on the use of URIs, RDF, and SPARQL – aimed at facilitating these principles.

The huge success and widespread adoption of the Linked Data approach has led to the availability of vast amounts of public data such as DBpedia, WordNet RDF or the initiative. More recently, these approaches started to get adopted by education institutions, with Linked Data technologies being used to expose public information regarding course offerings, open educational resources and educational facilities in a readily accessible and reusable way. While the very nature of the Linked Data approach thus clearly offers promising solutions that can potentially transform education, it is not yet adopted widely within the educational field.

The LinkedUp project is an FP7 Support Action that seeks to explore and exploit open and linked data for education. This includes data with an explicit educational purpose, as well as other data and information that may not have an explicit educational remit, but can usefully be applied to an educational context. We aim to organize a half-day workshop dedicated to the second competition on innovative and robust prototypes and demos for tools that analyse and/or integrate open web data for educational purposes.

Previous Workshops

The success of the Linked Data paradigm has triggered a wave of more pragmatic research efforts, which has been reflected in the proportion of Linked Data- related topics that are covered in previous ESWC conferences. While semantic technologies are well established and used within the eLearning community so far, there is still a lot of potential to adopt Linked Data principles to facilitate Web-based learning. The Vidi Competition is the second competition organized by LinkedUp. The selected submissions of the first competition, Veni, have been presented – along with a panel discussion – at the OKCon 2013 in Geneva, Switzerland. The workshop will also build upon our experiences with Linked Learning 2011 (at ESCW 2011), 2012 and 2013 (both at WWW 2013), which provided a forum for researchers and practitioners making innovative use of Linked Data technologies for educational purposes on the Web to discuss, exchange and disseminate their work.

Other relevant workshops include the LAK Data Challenge (at LAK 2013) and UWeb 2011 (User Profile Data on the Social Semantic Web, at ESWC 2011)
