ISWC 2026 — 25th International Semantic Web Conference

ISWC 2026, the 25th International Semantic Web Conference, runs October 25-29, 2026 at The Nicolaus Hotel in Bari, Italy, as a five-day in-person event. Run by the Semantic Web Science Association with Valentina Tamma as general chair, ISWC is the leading research forum for knowledge graphs, ontologies, linked data and knowledge representation — the technologies enterprises now pair with large language models for grounding and retrieval. Workshop and challenge days on October 25-26 include cross-over workshops with the AI, database, NLP and machine-learning communities and open challenge competitions, followed by the main conference.

• ✓Data-governance and interoperability leads

Most enterprise LLM programmes eventually hit the same wall: models need trustworthy, structured knowledge to ground answers, and that is what ISWC's community builds. A chief data officer or head of AI attending ISWC 2026 can assess which knowledge-graph, ontology and semantic-integration methods are mature enough to adopt, compare approaches through the challenge workshops, meet the researchers behind the relevant W3C standards, and recruit knowledge engineers — a skill set that is scarce and rarely found at general AI events.

• ✓Workshop and challenge days, 25-26 October 2026
• ✓Cross-over workshops bridging ISWC with other research communities (AI, databases, NLP, machine learning)
• ✓Challenge workshops: open competitions on Semantic Web problems with released datasets
• ✓Novel workshops on emerging topics and established workshops with a track record
• ✓Five-day in-person programme at The Nicolaus Hotel, Bari

• ★The 25th edition of the field's flagship venue — where the standards and methods behind enterprise knowledge graphs (RDF, SPARQL, ontologies) are researched first.
• ★Cross-over workshops explicitly bridge semantic-web research with the AI, database, NLP and machine-learning communities — the ground where knowledge graphs meet LLMs.
• ★Challenge workshops run open competitions on released datasets, giving practitioners concrete benchmarks rather than vendor claims.
• ★Research-first rather than vendor-led; industry presence (e.g. Graphwise presenting at the workshops) is as authors, not exhibitors.
