ISWC 2015 has some new features: A special research track has been added, named Empirical Studies and Experiments. The In-Use track has been updated to include Software. Additionally, a new trace is being introduced: Datasets and Ontologies track.
Although the calls for Research, Empirical Studies and Experiments, Datasets and Ontologies, In-Use and Software, and Doctroral Consortium have passed, the calls for Posters and Demos and Industry Track are still open, as well as the call for submissions to many workshops.
Please see the links to the right (or below) for the full list of calls.
