... judgments in training ex- amples. Kulesza and Shieber (2004) raised two main objections against regression for MT evalua- tions. One is that regression requires a large set of labeled training examples. ... classify its inputs; thus its outputs are discrete. In contrast, a regression model learns a continuous function that directly maps an input to a continuous value. An MT ev...

The conserved phenylalanine in CBM20 and invariant lysine in CBM21 are shown in black inversion. ... Mutational analysis of this site demonstrated a binding role [20]. Based on their sequences the starch-binding domains (SBD) have also been classified into families of carbo- h...

They state the problem of metonymy resolution as a classification task be- tween literal use of a word and a number of prede- fined metonymy ... results. 4 Finding the Distance to the Typical Context Set The algorithm is intended to determine whether a word (or an expression) in a given context is used literaly or not. As it was mentio...
