technology leaders in the area of Knowledge Engineering. Additional 
tracks can be proposed until Sep 14th, please contact 
dbpedia-events@xxxxxxxxx <mailto:dbpedia-events@xxxxxxxxx>.


 *

   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. https://www.timbr.ai/

 *

   GNOSS Knowledge Graph Builder: Give meaning to your organisation’s
   documents and data with a Knowledge Graph.
   https://www.gnoss.com/en/products/semantic-framework

 *

   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
   http://demo.nl.diffbot.com/. 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.


# 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.

Association & InfAI and the DBpedia 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.

Stay tuned and stay safe!
