The International Semantic Web Conference (ISWC) is the leading annual venue for research on the Semantic Web, linked data, and knowledge graphs. The 25th edition is held in Bari, Italy, covering ontology engineering, knowledge graph construction and embedding, entity linking, question answering over knowledge bases, reasoning, and the application of semantic technologies in domains such as biomedicine, cultural heritage, and enterprise data integration. ISWC has a strong record of publishing work that shapes the direction of the field - the conference proceedings are among the most cited in knowledge representation and the web of data. The Nicolaus Hotel conference venue is Bari’s main convention facility, and the late October timing puts the conference in ideal southern Italian weather - warm enough for outdoor evenings in the old town without the summer heat. Bari is directly served from many European airports and is an excellent base for exploring Puglia.
