Procedure for quantitatively comparing the syntactic coverage of English grammars

摘要: The problem of quantitatively comparing the performance different broad-coverage grammars English has to date resisted solution. Prima facie, known appear disagree strongly with each other as elements even simplest sentences. For instance, Steve Abney (Bellcore), Ezra Black (IBM), Dan Flickinger (Hewlett Packard), Claudia Gdaniec (Logos), Ralph Grishman and Tomek Strzalkowski (NYU), Phil Harrison (Boeing), Don Hindle (AT&T), Bob Ingria (BBN), Mitch Marcus (U. Pennsylvania) recognize in common only following constituents, when grammarian provides single parse which he/she would ideally want his/her grammar specify for three sample Brown Corpus sentences:The famed Yankee Clipper, now retired, been assisting (as (a batting coach)).One those capital-gains ventures, fact, saddled him (with Gore Court).He said this constituted a (very serious) misuse (of (Criminal court) processes).
