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 2025 Challenge, in which you
define an open competition on a problem of your choice within the Semantic
Web domain.

Topics:

For ISWC 2025, 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
   -

   Graph embeddings and graph neural networks
   -

   Query and reasoning scalability
   -

   Open information extraction
   -

   Neurosymbolic reasoning
   -

   Semantic Web and data mining
   -

   Semantic Web, machine learning, and neuro-symbolic AI
   -

   Link prediction
   -

   Question answering
   -

   Stream processing and reasoning
   -

   Semantic table understanding
   -

   Agents (especially using neuro-symbolic methods) and agentic workflows
   -

   Retrieval Augmented Generation (RAG)


Proposal Stage:

ISWC 2025 will run multiple challenges with the aim of evaluating and
comparing software solutions for the Semantic Web and Knowledge Graphs in a
systematic way. To propose a challenge, you are required to:

   -

   Specify a task to be addressed.
   -

   Provide an evaluation dataset.
   -

   Define evaluation measures to compare the performance of participating
   systems.
