- IWCS is the biennial International Conference on Computational Semantics, a key event organized by SIGSEM.
- IWCS is also known as the International Winter Conference on Semantics, following a suggestion by Sebastian Pado. At the IWCS in Potsdam in 2013, organizer Alexander Koller sharply summarized the relation between IWCS and low temperatures: "you can take IWCS out of the winter, but you can't get the winter out of IWCS".
- IWCS was founded by Harry Bunt, and organized in Tilburg, see official homepage IWCS. Since 2010 Johan Bos and Stephen Pulman form a steering committee to ensure continuity of IWCS.
- The next IWCS is planned for 2015.
