The sequences of the CCK receptors are known [44] ... evi- dence that polyprotodont opossums produce immuno- globulins in the pouch [26].

... word pairs that are not likely to be good predictors of discourse relations. To test this hypothesis, we decided to carry out a second experiment that used as predictors only a subset of the word ... aimed at building robust discourse-relation classification sys- tems. To build such systems, we train a family of Naive Bayes classifiers on a large set of examples that are generated aut...
