Constraints are widely used in linguistics, computer science, and psychology. How they are used, however, varies widely according to the research domain: knowledge representation, cognitive modelling, problem solving mechanisms, etc. These different perspectives are complementary, each one adding a piece to the puzzle. For example, linguistics proposes in-depth descriptions implementing constraints in order to filter out structures by means of description languages, constraint ranking, etc. The constraint programming paradigm, on the other hand, shows that constraints have to be taken as a systematic whole and can thus play a role in building the structures (or can even replace structures). Finally, psycholinguistics experiment have been made, investigating the role of constraint systems for cognitive processes in comprehension and production, as well as addressing how they can be acquired.

This workshop is the sixth of its kind and takes place 27 September 2011 affiliated with CONTEXT '11: The 7th International and Interdisciplinary Conference on Modeling and Using Context 2011.

The collocation with the Context'11 conference underlines the application of constraints for context comprehension and discourse modelling.
