[ANN] DBpedia Autumn Hackathon, starting Sept 21st

Hi LODers,

I forgot the exact policy of posting here. This time it is the DBpedia 
hackathon, which I think is ok. Note that DBpedia will start to produce 
thousands of structural knowledge graphs that help find and crystallize 
LOD subcommunities. The Dutch National Knowledge Graph is a pilot for 
this. At the Hackathon final event on Oct 5th and at the Knowledge 
Graphs in Action at Oct 6th, I will give a short presentation there to 
introduce the architecture briefly.

Dear DBpedians, Linked Data savvies and Ontologists,


We would like to invite you to join the DBpedia Autumn Hackathon 2020 as

experience the latest technology provided by DBpedia Association 
members. The hackathon is part of the Knowledge Graphs in Action 
conference on October 6, 2020. Please check here:

# 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 <mailto: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. 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!
