Precision grammars can be very rich resources for natural language processing, but they are also expensive to create. At the same time, much has been learned from existing large scale grammar development projects which is applicable cross-linguistically. The LinGO Grammar Matrix aims to reduce the cost of creating precision grammars by abstracting out a cross-linguistic core grammar and then providing a series of reusable analyses of recurrent, non-universal phenomena through a web-based grammar customization system. In addition to practical applications, this approach provides a new angle on the linguistic study of variation and typology.
