Dear DBpedians, Linked Data savvies and Ontologists,

We would like to invite you to join the DBpedia Autumn Hackathon 2020 as a new format to contribute to DBpedia, gain fame, win small prizes and experience the latest technology provided by DBpedia Association members. 
The hackathon is part of the Knowledge Graphs in Action conference on October 6, 2020.

Member Tracks 

The member tracks are hosted by DBpedia Association members, who are technology leaders in the area of Knowledge Engineering. Additional tracks can be proposed until Sep 14th, please contact dbpedia-events@infai.org.

  • timbr SQL Knowledge Graph: Learn how to model, map and query ontologies in timbr and then model an ontology of GDELT, map it to the GDELT database, and answer a number of questions that currently are quite impossible to get from the BigQuery GDELT database. Cash prizes planned. 
  • GNOSS Knowledge Graph Builder: Give meaning to your organisation’s documents and data with a Knowledge Graph. 
  • ImageSnippets: Labeling images with semantic descriptions. Use DBpedia spotlight and an entity matching lookup to select DBpedia terms to describe images. Then explore the resulting dataset through searches over inference graphs and explore the ImageSnippets dataset through our SPARQL endpoint. Prizes planned. 
  • Diffbot: Build Your Own Knowledge Graph! Use the Natural Language API to extract triples from natural language text and expand these triples with data from the Diffbot Knowledge Graph (10+ billion entities, 1+ trillion facts). Check out the demo. All participants will receive access to the Diffbot KG and tools for (non-commercial) research for one year ($10,000 value).

Dutch National Knowledge Graph Track

Following the DBpedia FlexiFusion approach, we are currently flexi-fusing a huge, dbpedia-style knowledge graph that will connect many Linked Data sources and data silos relevant to the country of the Netherlands. We hope that this will eventually crystallize a well-connected sub-community linked open data (LOD) cloud in the same manner as DBpedia crystallized the original LOD cloud with some improvements (you could call it LOD Mark II). Data and hackathon details will be announced on 21st of September.

Organising committee:

Improve DBpedia Track

A community track, where everybody can participate and contribute in improving existing DBpedia components, in particular the extraction framework, the mappings, the ontology, data quality test cases, new extractors, links and other extensions. Best individual contributions will be acknowledged on the DBpedia website by anointing the WebID/Foaf profile.

(chaired by Milan Dojchinovski and Marvin Hofer from the DBpedia Association & InfAI and the DBpedia Hacking Committee, please message @m1ci to volunteer to the hacking committee)

DBpedia Open Innovation Track 

(not part of the hackathon, pre-announcement)

For the DBpedia Spring Event 2021, we are planning an Open Innovation Track, where DBpedians can showcase their applications. This endeavour will not be part of the hackathon as we are looking for significant showcases with development effort of months & years built on the core infrastructure of DBpedia such as the SPARQL endpoint, the data, lookup, spotlight, DBpedia Live, etc. Details will be announced during the Hackathon Final Event on October 5.

To the DBpedia Community!

Can you believe ..?

… that it has already been eleven years since the first DBpedia dataset was released? Eleven years of development,  improvements and growth, and now, 13 billion pieces of information are comprised in our last DBpedia release. We want to take this opportunity to send out a big thank you to all contributors, developers, coders, hosters, funders, believers and DBpedia enthusiasts who made that possible. Thank you for your support.

But, apart from our data sets, there is much more DBpedia has been doing., especially during the past year. Think about the success story of Wouter Maroy, a GSoC 2016 student who got the opportunity to do a six weeks internship at our DBpedia office in Leipzig and who is still contributing to DBpedia’s progress.

All in all, 2017 was highly successful and full of exciting events. Remember our 10th DBpedia Community Meeting in Amsterdam featuring an inspiring keynote by Dr. Chris Welty, one of the developers at IBM computer Watson. Our DBpedia meetings are always a great way to bring the community closer together, and to not only meet our DBpedia audience but also new faces. Therefore, we have already started to plan our community meetings for 2018.

We hope to see you in Poznan, Poland, in spring and to meet you during the SEMANTiCS Conference in Vienna, from 10th – 13th of September 2018. Additionally, if everything goes according to plan, we will be mentoring young DBpedia enthusiasts throughout summer in GSoC 2018 and meet the US DBpedia community in autumn this year. Follow us on Twitter or check our Website for the latest News.

And last but not least, this year we plan something special. DBpedia intends to participate in Coding DaVinci – Germany’s first open cultural hackathon, which happens to take place in Leipzig, right around the corner. Aspiring data enthusiast will develop new creative applications from cultural open data. The kick-off is in early April, followed by 9 weeks of cooperative coding. We are eagerly awaiting the start of this event.

We do hope, we will meet you and some new faces during our events this year. The DBpedia Association want to get to know you because DBpedia is a community effort and would not continue to develop, improve and grow without you. Thank you and see you soon…
