Call for semantic web challenge proposals



ISWC 2021 Call For Challenges


A great way to advance the state of the art in a given domain is to create competition. We invite you to propose an ISWC 2021 Challenge, in which you define an open competition on a problem of your choice within the Semantic Web domain.


Proposal Stage


ISWC 2021 will run multiple challenges with the aim to evaluate and compare software solutions for the Semantic Web in a systematic way. In order to propose a challenge, we ask you to:

  • ● specify a task to be addressed
  • ● provide an evaluation dataset
  • ● define evaluation measures to compare the performance of participating systems

Challenge Stage


After acceptance of the challenge to ISWC 2021, challenge organizers are responsible for:

  • ● providing a website
  • ● publishing challenge tasks, datasets, and measures
  • ● selecting participants who can present their solutions at ISWC 2021


Showcase Stage


At ISWC 2021, each challenge will receive one slot during the main conference, during which contestants present their accepted solutions. Participants will also have the option to present their systems during the poster and demo session.


Topics


For ISWC 2021, Challenge proposals are invited for any challenge involving Semantic Web tasks, including but not limited to

  • ● Ontology and knowledge graph alignment
  • ● Ontology and knowledge graph quality assurance (QA)
  • ● Knowledge graph construction and refinement
  • ● Query and reasoning scalability
  • ● Open information extraction
  • ● Semantic Web and data mining
  • ● Link prediction
  • ● Question answering
  • ● Stream processing and reasoning
  • ● Semantic table understanding


ISWC 2021 will be a virtual conference that will take place on 24-28 October. Recent Challenge examples can be found at https://iswc2020.semanticweb.org/program/semantic-web-challenges/ and
