... Introduction Implicit discourse relations abound in text and readers easily recover the sense of such relations during semantic interpretation. But automatic sense prediction for implicit relations is ... shortcomings and propose modifications. Our best com- bination of features outperforms the base- line from data intensive approaches by 4% for comparison and 16% for...

... if all instances that are assigned sense a have gold sense x, then sense a is mapped to gold sense x. Therefore, if the proportion of junk senses in the map- ping instances is low, their in uence ... report higher results again using in- domain training data, so we would expect to see further gains again over the I2R system in following this path. Overall, these results agree wi...

WSD systems have been far more successful in distinguishing coarse- grained senses than fine-grained ones (Navig- li, 2006), but ... whether such fine-grained distinctions even reflect how human beings represent word meaning. Human annotators have trouble distinguishing such fine-grained senses reliably. Interannotat...
