International Semantic Web Conference (ISWC)

The International Semantic Web Conference (ISWC) is the leading conference for research on Semantic Web topics. It is held annually and is the successor of the Semantic Web Working Symposium (SWWS).

The SWSA Ten-Year Award recognizes most influential papers from the ISWC proceedings ten years prior.

The Semantic Web Conference Corpus provides access to information about all ISWC conferences in RDF. You can browse and search information on papers that were presented, people who attended, and other things that have to do with the main conferences and workshops.
