To investigate if our WSD systems are biased in favor of more frequent senses, we calculated the recall performance by sense predominance in the Nat test setting (in the Uni test setting we assume no sense predominance).
we separately calculated the recall performance of IMS and UKB on items tagged in the test set with the first (i.e., most frequent) sense of each pseudoword, the second (i.e., second most frequent) sense, and so on.
