Fluid Construction Grammar (FCG) is a computational framework for exploring issues in construction grammar. This unification-based grammar formalism uses feature structures for representing linguistic knowledge, and it can apply the same constructions in both parsing and production. FCG also comes with a web interface for visualizing the application of constructions during language processing and the resulting structures. FCG can be used on any software platform with a running Common Lisp programming environment.
