Unlike dependency grammars, CCG requires an inventory of lexical categories. Note that this model generates only one CCG category but uniquely defines the two children of a parent node. Since our approach is based on a lexicalized formalism such as CCG, our system automatically induces lexicons that pair words (or, in our case, POStags) with language-specific categories that capture	./cache/work_j4jyyr4gnrbelgfykpcumrgui4.pdf	./txt/work_j4jyyr4gnrbelgfykpcumrgui4.txt
