Past work on English coordination has fo- cused on coordination scope disambigua- tion. In Japanese, detecting whether coor- dination exists in a sentence is also a prob- lem, and the state-of-the-art alignment- based method specialized for scope dis- ambiguation does not perform well on Japanese sentences. To take the detection of coordination into account, this paper in- troduces a ‘bypass’ to the alignment graph used by this method, so as to explicitly represent the non-existence of coordinate structures in a sentence. We also present an effective feature decomposition scheme based on the distance between words in conjuncts.
