Korean Combinatory Categorial Grammar and Statistical Parsing

Korean Combinatory Categorial Grammar (KCCG) is an extendedcombinatory categorial grammar formalism to capture thesyntax and interpretation of a relative freess word order, longdistance scrambling, and other specific characteristics of Korean.KCCG formalism can uniformly handle word order variations amongarguments and adjuncts within a clause, as well as in complexclauses and across clause boundaries, i.e. long distancescrambling. The approach we develop takes advantage of the ability of CCGfor type raising and composition along with the ability of variablecategories and unordered argument modeling for relatively freeword order treatment (Lee et al., 1994; Lee et al., 1997).We apply a probability model and heuristics using Koreancharacteristics to our KCCG parser.Results of the experiments on varioustext genre show that the KCCG parser performsat 87.67/87.03% constituent precision/recall.
