Call for Papers ESWC 2021 Problems to Solve Before You Die


This track is new at ESWC 2021, and it focuses on hard, longstanding or paradigm-breaking open problems. The goal of the track is the identification or even creation of new research trends and topics in or related to the Semantic Web.

  • Suggest “millennium problems” and ideas of the Semantic Web which should be solved
  • What your contribution could be
    • Suggestions for new research fields or paradigms
    • Formulations of fundamental trade offs and limitations
    • Suggestion of innovative applications and ideas never heard of before
    • Suggestion of fruitful syntheses with other domains of computer science (or other fields) that haven’t been tried out before
    • Suggestions and ideas of new approaches and solutions for hard, longstanding, and paradigm-breaking problems of our field
  • What your contribution will need
    • A clear formulation of the problem
    • An argument why this problem should be solved
      • i.e., what new killer apps would be possible our how our daily life would improve if this were solved
    • An analysis what has been done so far for tackling this
      • leading to an argument why it has not been solved so far
  • What your contribution won’t be
    • Here’s an artificial problem I’ve made up to have a unique selling position for my research
    • I’m stuck on this problem with my thesis, please help me
    • Merely an exercise:
      “If you can solve it, it is an exercise; otherwise it’s a research problem.”
      (Richard Bellman, when asked by a student how to distinguish between exercises and research problems, as quoted by Donald Knuth)
