In Japanese, zero references often occur and many of them are categorized into zero ex- ophora, in which a referent is not mentioned in the document. However, previous studies have focused on only zero endophora, in which a referent explicitly appears. We present a zero reference resolution model considering zero exophora and author/reader of a docu- ment. To deal with zero exophora, our model adds pseudo entities corresponding to zero exophora to candidate referents of zero pro- nouns. In addition, we automatically detect mentions that refer to the author and reader of a document by using lexico-syntactic patterns. We represent their particular behavior in a dis- course as a feature vector of a machine learn- ing model. The experimental results demon- strate the effectiveness of our model...
