Precision grammars represent knowledge engineering for natural language parsing (assigning syntactic and semantic structure to sentences) and generation (assigning surface strings to semantic representations). Recent advances in parsing and generation technology make it feasible to use precision grammars in natural language processing tasks demanding real&345;time response from the parsing system.  In this talk, Emily Bender presents the LinGO Grammar Matrix, a linguistic knowledge resource designed to allow for rapid prototyping of scalable precision grammars of any human language.
