Paper about SlideWiki accepted at CSEDU Conference 2013

Our paper CrowdLearn: Crowd-sourcing the Creation of Highly-structured E-Learning Content (by Darya Tarasowa, Ali Khalili, Sören Auer, Jörg Unbehauen) was accepted as a full paper at the 5th International Conference on Computer Supported Education (CSEDU2013). The conference takes place May 6-8 in Aachen, Germany. Meanwhile you can check our Semantic Data Web lecture series on SlideWiki.

We now almost completed the first lectures on RDF and RDF-Schema and aim to complete the whole series by May. We are also working on translating this to different languages (e.g. Persian: http://slidewiki.org/deck/870). There are also lecture series on Semantic Web Services and Intelligent Systems in preparation. Please feel invited to contribute to these and other lectures – we also plan to add many other features to SlideWiki in the near future. This way, we hope to make educational material (on Semantic Web technologies and in general) much more interactive, multilingual and accessible.

Two AKSW Papers at WWW

The AKSW papers “Sorry, I don’t speak SPARQL – Translating SPARQL Queries into Natural Language” and “Question Answering on Interlinked Data” were accepted as full research papers for presentation at WWW2013. The first paper presents SPARQL2NL, a framework which  deals with the translation of SPARQL queries (and RDF triples) into natural language. The intention behind SPARQL2NL is to support for lay users who want to know what happens in the backend of the semantic system they are using. The framework has already been integrated into two pieces of software, i.e., the question answering engine TBSL and BioASQ‘s annotation tool for bio-medical questions. Moreover, it was shown to be of help for both SPARQL experts and non-experts. Check out the demo here. The second paper focuses on keyword search and question answering on interlinked data sets and shows how links across knowledge bases can be used to answer questions that require aggregating knowledge from several knowledge bases. The final versions of the papers will be made available soon. Please check them out and let us know what you think.

Looking forward to seeing you at WWW,
Axel for AKSW

Indian PhD Student in Tatort !!!

In a wonderful coincidence, an Indian PhD student from our group Amrapali Zaveri is going to appear in one of the episodes of Tatort. Now for those of you who do not know, Tatort (English title: Crime Scene) is a very old (since 1970) and popular German TV serial based on crime. Each major city in Germany has its own Tatort.

Amrapali was lucky enough for being offered a role as an extra on one of the episodes “Schwarzer Afghane”. She plays an Afghan whose family has died in a fire and had to act sad and cry about it. The shooting was done last year in Espenhein, near Leipzig. A few shots from the shooting are seen in the image below. Also starring are Simone Thomalla, Martin Wuttke (seen in the picture below) and Maxim Mehmet. Who says scientists aren’t real people?! “There’s more to us than the geeks and nerds that we’re portrayed as”: http://goo.gl/C9yZd 😉

The episode will appear on 17th March, 2013, Sunday at 8:15 p.m on DasErste (ARD). So mark it in your calendar, get your popcorn ready and tune in for some India-Afghan-German drama !

First Public Beta of SlideWiki.org

On the AKSW blog we occasionally announce pre-views of tools we develop and release widely later on. Now, we are excited to grant you a peek on our SlideWiki.org crowd-sourcing collaboration platform for educational content. Slidewiki is for educational content (presentations, tests) what MediaWiki is for texts, OpenStreetmaps for spatial data or GitHub for source code. SlideWiki is completely browser-based and users can edit, branch and merge all decks and slides available on SlideWiki under the CC-BY-SA license. With SlideWiki communities can collaborate to create all kinds of presentations, self-assessment questionnaires, diagrams etc. SlideWiki also supports the automatic translation in 54 languages and the manual refinement of the translated content. Ultimately, we aim to make educational content much more interactive, collaborative, engaging, open and reusable. More information about SlideWiki’s features can be found in the documentation presentation.

A few comprehensive lecture series are already available on SlideWiki. AKSW is currently preparing a lecture series on the Semantic Data Web, which can be seen here: slidewiki.org/deck/750

European Data Forum 2013 – Call for Contribution

The European Data Forum (EDF) is a regularly scheduled (yearly) meeting place for industry, research, policy makers, and community initiatives to discuss the challenges and opportunities of (Big) Data in Europe.

Our aim is to bring together all stakeholders involved in the data value chain to exchange ideas and develop actionable roadmaps addressing these challenges and opportunities in order to strengthen the European data economy and its positioning worldwide.

An equally important goal of the European Data Forum is to create and foster a truly European Big Data community. This emerging community will enable promising ideas to move from the stage of research questions all the way to successful deployment and the acquisition of capital; in the same time, its stakeholders will mutually reinforce commercial strategies that require a forward-looking, dynamic, and well-integrated EU-wide industry and venture capital.

The next edition of the EDF will be held in Dublin, Ireland on April 9-10, 2013. The program will consist of a mixture of presentations and networking sessions by industry, academics, policy makers, and community initiatives on topics ranging from research and technology development, to training and knowledge transfer, and commercialization.

We are seeking inspiring presentations addressing fundamental technical, application, socio-economic and policy-related topics related to Big Data management and analytics. The presentations will vary in format and focus depending on the main expected audience and their contributors. They will be reviewed by the Organization Committee of the Forum according to their relevance to the scope and purpose of the event and the specific topics we foresee to target, which are listed in the following:

  • Is the European economy ready for Big Data? (novel innovation and business models for open and Linked Data, platforms and marketplaces, policies, strategies for the development of data ecosystems) What are specifically European challenges and opportunities in this space? In particular, we invite talks on developments, case studies, and experience reports related to the legal environment, as well as privacy and provenance issues rising in this new context.
  • Are we reaching out to relevant stakeholders? (application scenarios and specific technical and non-technical requirements of Big Data providers and consumers in sectors such as Smart Cities, Environmental Research, Geo-Spatial Information, eScience, social media) Again, the 2013 edition of the EDF particularly welcomes presentations addressing not just the R&D component of these scenarios, but foremost issues related to privacy and access control, and the broader impact of these exciting developments on the civil society.
  • What does Europe provide in terms of innovative Business Intelligence solutions (SMEs and other technology providers offering tools to make use of Big Data, taking into account issues such as heterogeneity, quality, reliability etc) and what is or should be its competitive advantage in this domain? In connection to this third dimension, we invite talks proposing or reporting on research agendas and roadmaps for science, technology and innovation, in particular in related to research framework programmes such as Horizon 2020, as well as framework conditions which are essential for meeting Europe’s ambitions towards a profitable data economy. Examples of such conditions include standardization needs and current activities, the development of curricula for professional training, and commercialization opportunities.

We distinguish between the following presentations opportunities:

  • Presentations with a practical, industry- or user-oriented focus by representatives of technology providers, adopters, and user organizations.
  • Presentations with a theoretical or technical, but rather research-oriented focus by representatives of academia and research centers.
  • Presentations with a specific focus on impact-creation activities including policy development, roadmapping, standardization, exploitation and training.

Each proposal for a presentation will have to provide the following information:

  • Type of presentation proposed
  • Title of the presentation
  • Summary of the presentation (100 words)
  • Extended abstract of the presentation (4000 words, only for research contributions)
  • Presenters’ short biography

Submissions should be sent via mail to: edf2013@data-forum.eu

The deadline for submissions is: 22nd Feb 2013, 02.00pm CET
