How well do supervised and unsupervised NLP systems perform when used uncustomized, out-of-the-box on new domains, and how can we best design our systems for robust open-domain performance? Our ... systematically assess the value of using web-scale N-gram data in state-of-the-art supervised NLP classifiers. We compare classifiers that include or ex- clude features for the counts of various N-grams,...
