Abstract

How effective is stemming? Text normalization? Stemming experiments test two hypotheses: one term (+stemmer) or two (-stemmer). The truth lies somewhere in between. The correlations, p, between a word and its variants (e.g., +s, +ly, +uppercase) tend to be small (refuting the one term hypothesis), but non-negligible (refuting the two term hypothesis). Moreover, p varies systematically depending on the words involved; it is relatively large for a good keyword, p(hostage, hostages) = 0.5, and small for pairs with little content, p(anytime, Anytime) = O, or conflicting content, p(continental, Continental) = 0,
