Broad-coverage grammars tend to be highly am- biguous. When such grammars are used in a restricted domain, it may be desirable to spe- cialize them, in effect trading some coverage for a reduction in ambiguity. Grammar specializa- tion is here given a novel formulation as an opti- mization problem, in which the search is guided by a global measure combining coverage, ambi- guity and grammar size. The method, applica- ble to any unification grammar with a phrase- structure backbone, is shown to be effective in specializing a broad-coverage LFG for French.
