The Use of Instrumentation in Grammar Engineering

This paper explores the usefltllmss of a technique from software engineering, (:ode instrumentation, tbr the developlnent of large-scale natural language grammars, hltbrlnation about the usage of gralnmar rules in test and corpus sentences is used to ilnprove grammar and testsuite, as well as adapting a grammar to a specific genre. Results show that less than half of a large-coverage grmnmar for German is actually tested by two large testsuites, and that 10 30% of testing time is redundant. This methodology applied can be seen as a re-use of grammar writing knowledge for testsuite compilation. The construction of genre-specific grmmnars results in peribrmance gains of a factor of four.
