I am developing the world’s first broad-coverage construction grammar for English that works for both comprehension and production. You can test the grammar at this webpage (Note: our server is under maintenance, check back later for a new and improved version).
The grammar will soon be released as part of the open source language technologies – including Fluid Construction Grammar – that I have been co-developing at Sony CSL Paris and the VUB Artificial Intelligence Lab. If you are using our language technologies and are developing on a Mac with Lispworks, you can check out some of my video tutorials here for recent developer tools that I implemented:
If you are new to Fluid Construction Grammar, you can get your first hands-on experience with my FCG Editor (only Mac and only limited functionality).
