A bilingual approach based on a comparable corpus is proposed to better detect and to resolve Chinese zero pronouns. The concept of English equivalent sentence is defined firstly. Then the equivalent sentence is employed to redefine the distance between sentences and to extract bilingual word alignment features. In this way, both zero pronoun detection and resolution of the baseline system from bilingual perspective are improved. The experiments conducted on the OntoNotes5.0 corpus show that the proposed approach can significantly outperform the state-of-the-art system.
