More than 140 DBpedia enthusiasts joined the Community Meeting in Amsterdam.

After the success of the last two community meetings in Sunnyvale and in Galway, we thought it is time to go Orange again. During the SEMANTiCS 2017 in Amsterdam, Sep 11-14, the DBpedia Community met on the 14th of September. First and foremost, we would like to thank the Institute for Applied Informatics for supporting our community and many thanks to the Meervaart Theatre and the SEMANTiCS for hosting our community meeting.

Opening Session

Chris Welty

During the opening session, Chris Welty, Google Researcher, presented Even the Changes Are Changing: A New Age of Cognitive Computing. He introduced the impact and challenges of question answering & AI as well as the development of Jeopardy through technical changes. Victor de Boer from the VU University talked about Semantic Technology for Development: Semantic Web without the Web?. He demonstrated the use of semantic technology in the challenging technical environment of developing countries. Both talks illustrated the ever growing importance of semantic technology and AI each placed at opposite sites of the technology spectrum, from Raspberry PIs to High Performance Clusters.

 

Showcase Session

The DBpedia Showcase Session started with an interactive interview. Sebastian Hellmann (AKSW/KILT) talked with Jan-Bart de Vreede (Kennisnet, former member of the Wikimedia Foundation) about the challenges of growing an open community and creating a more formal structure. They discussed advantages, pitfalls and what lessons can be learned from other communities such as Wikimedia. Afterwards Markus Freudenberg (AKSW/KILT) introduced the highlights of the 2016-10 DBpedia Release.

At this session, five speakers presented how to utilize DBpedia in novel and interesting ways. Including:

  • Virtuoso 8 and Scalable Attributed-based Access Controls (ABAC) by Patrick van Kleef (Openlink Software)
  • Learning to Associate DBpedia Entities like Humans by Joern Hees (DFKI) (demo)
  • Towards Using UnifiedViews for Executing DBpedia Data Extraction and Curation Tasks by Tomas Knap (Semantic Web Company)
  • Sustainable Linked Data Generation: The Case of DBpedia by Wouter Maroy (imec)
  • Mappings UI by Ismael Rodríguez (Polytechnic University of Catalonia)
Wouter Maroy & Ismael Rodríguez

Parallel Session

As a regular part of the DBpedia Community Meeting, we had two parallel sessions in the afternoon where DBpedia newbies can learn about what DBpedia is and how to use the DBpedia datasets. Participants who wanted to learn DBpedia basics joined the tutorial session by Markus Freudenberg (DBpedia Release Manager). The DBpedia Association Hour provided a platform for the community to discuss the results of the DBpedia Strategy Survey 2017. This survey was prepared by Sören Auer and the DBpedia Board members to get to know what the DBpedia Community thinks about DBpedia’s strategic priorities and how the funds of the DBpedia Association should be spent. Even if 45 minutes were not adequate to review all survey questions, this session proved to be beneficial due to a really agile and dynamic discussion. A better cooperation and communication between the Association and the different national and language chapter is only one suitable key which was embraced by the community to facilitate problem solving and DBpedia’s organization.

Afternoon Track

The sessions in the afternoon highlighted two important fields of research and development, namely DBpedia Ontology and DBpedia & NLP. At the DBpedia Ontology Session, Gustavo Publio (AKSW/KILT) presented data quality issues in DBpedia and highlighted the challenges on redesign the DBpedia Ontology (slides).  Wouter Maroy (imec) and Ismael Rodríguez (Polytechnic University of Catalonia) showcased the DBpedia Mappings Front-End Administration, which they created during this year’s Google Summer of Code project. If you are interested in career opportunities at DBpedia, check out Wouter’s success story here.

At the same time, Milan Dojchinovski (AKSW/KILT) chaired the DBpedia & NLP session with five very interesting talks. In the following you will find all presentations given during this session:

Dutch DBpedia Hour & Joint Workshop

Enno Meijers (National Library of the Netherlands) chaired the Dutch DBpedia Hour. In this open session members of the Dutch DBpedia Language Chapter discussed tasks and responsibilities for sustaining and developing the Dutch DBpedia as well as communication, technical infrastructure and content improvement of the DBpedia Dutch Language Chapter. The reference for this discussion was the tasks and responsibilities stated in the Memorandum of Understanding signed by Huygens ING, Koninklijke Bibliotheek, Vrije Universiteit Amsterdam, iMec and Beeld en Geluid. Outcome of this session was an agreement on the approach for creating an operational plan.

Simultaneously, DBpedia joint a session with the Workshop “Linked Data Quality Assessment and Improvement from Academia to Industry”. The presentations are available below:

DBpedia in Dutch: formalizing the chapter by signing the Memorandum of Understanding

The DBpedia community and members from over 20 countries work hard to localize and internationalize DBpedia and support the extraction of non-English Wikipedia editions as well as build a data community around a certain language, region or special interest. The chapters are part of the DBpedia executives and have taken on responsibility to contribute to the infrastructure of DBpedia.

Hereby we proudly announce that DBpedia in Dutch is the first chapter which signed the Memorandum of Understanding (MoU). There are various intentions why they already signed the MoU: First of all they support the goals of the DBpedia Association, secondly they strengthen their own chapter and community of contributors and thirdly they improve the cooperation with the Dutch research infrastructure and the Dutch Digital Heritage. The cooperation was initiated by Koninklijke Bibliotheek (National Library of the Netherlands) and Huygens ING (research institute of History and Culture).

Dr. E.J.B. Lily Knibbeler (director of KB) and Prof. Dr. Lex Heerma van Voss (director of Huygens ING) signing the MoU on 12th September 2016 in The Hague.

Other partners like imec/Ghent University and Institute of Sound and Vision have signed as well and became an executive partner of the DBpedia Association. The Vrije Universiteit will join soon. It is a cooperation between these Dutch organizations as well as the NL-DBpedia community.

The Dutch Chapter has provided a Sample DBpedia Chapter Memorandum of Understanding (MoU) to use as a template for further chapters. If you use DBpedia and want us to keep going forward, we kindly invite you to donate and help DBpedia to grow.

Have you backlinked your data yet? – A retrospective of the 6th DBpedia community meeting in The Hague

 

We thought it was about time to go orange again, meet the Dutch DBpedia Chapter and to meet and celebrate the growing dutch DBpedia community. Thus, following our successful US-event past November, the National Library of the Netherlands hosted the 6th DBpedia community meeting in The Hague on February 12th. 

First and foremost, we would like to thank TNO for organizing the pre-event and the National Library of the Netherlands, especially Menno Rasch (Director of KB operations), for sponsoring the catering during the DBpedia community meeting.

Pre-event

Before diving into DBpedia topics, we had a welcome reception on February 11th with snacks and drinks at TNO – New Babylon.  Around 40 people from the DBpedia community, members from TNO and its Data Science Department and representatives from the Platform Linked Data Netherlands engaged in vital exchanges about Linked Data topics in the Netherlands.

Sebastian Hellmann gave a short introduction about DBpedia and the recently found DBpedia Association. After Jean-Louis Roso talked about the TNO Data Science Department and current developments and projects, Erwin Folmer presented the platform Linked Data Netherlands (PiLOD).

A poster and demo session right after gave people from TNO the opportunity to present and discuss projects currently carried out at TNO.

Following, you find a short list of poster-presentation during the pre-event:

The following social gathering with snacks and drinks, encouraged talks about current developments in the DBpedia community and about ongoing projects. According to TNO representative Laura Daniel, the pre-event was very successful. She summarized the evening of the welcome reception: “It was very inspiring to see the DBpedia community in action. There were lots of interesting projects that use DBpedia as well as lively discussions on the challenges faced by the community, and of course, the event was a great opportunity for networking!”

After Lunch Track

DBpedia is one of the biggest and most important focal point of the Linked Open Data movement. Thus, the after-lunch-track focused very much on DBpedia Usages during the dedicated showcase session, which started with the new DBpedia & DBpedia+ Data Stack  release (planned for  2016-04).

Afterwards, the session continued with further DBpedia related discussions, in which various practical DBpedia matters such as DBpedia in the EUROPEANA Food and Drink project, the use of DBpedia for improved vaccine information systems or using Elasticsearch + DBpedia to maintain a searchable database of global power plants were tackled.

Afternoon Track

The afternoon track came along with four DBpedia highlight-sessions, namely DBpedia and Ontologies, DBpedia and Heritage, DBpedia hands-on development and DBpedia and NLP. Firstly, the DBpedia ontology group discussed possible ontology usages and presented the results of the latest DBpedia Ontology survey. In the following 75 minutes during the DBpedia and Heritage session, special challenges and opportunities of reference data for digital heritage were addressed by experts from EUROPEANA, iMinds, RCE and KB, the National Library of the Netherlands. Thirdly, members of the DBpedia Association and the AKSW/KILT group from Leipzig led a practical session for developers and DBpedia enthusiasts to talk about technical issues and challenges in DBpedia as well as they held a Tutorial session for DBpedia Newbies.

The end of the event was dedicated to NLP and the application of Linked Data on Language Technologies, especially entity linking, topics which are of vital importance for the research of AKSW/KILT members at the University of Leipzig.

Following, you find a list of all presentations given during the meeting.

All slides and presentations are also available on our Website and you will find more feedback and photos about the event on Twitter via #DBpediaDenHaag.
