Empty categories represent an impor- tant source of information in syntactic parses annotated in the generative linguis- tic tradition, but empty category recovery has only started to receive serious atten- tion until very recently, after substantial progress in statistical parsing. This paper describes a unified framework in recover- ing empty categories in the Chinese Tree- bank. Our results show that given skele- tal gold standard parses, the empty cate- gories can be detected with very high ac- curacy. We report very promising results for empty category recovery for automatic parses as well.
