Is the grammar builder limited to the design of simple grammars or can it be used for more complex ones too ?
With the grammar builder you can design complex multislot grammars. You can design complex linguistic graphs with distributed semantics. For each node of the grammar, it is possible to define semantic processing, as well as global processing for the entire grammar. Spelling, concatenations of strings, calculations etc. can be very quickly defined. With the grammar builder you can even define logical implications between distant concepts. External grammars can be inserted at any point with a simple drag&drop from the libraries.
