Appositions are adjacent NPs used to add information to a discourse. We propose systems exploiting syntactic and seman- tic constraints to extract appositions from OntoNotes. Our joint log-linear model outperforms the state-of-the-art Favre and Hakkani-Tu?r (2009) model by ?10% on Broadcast News, and achieves 54.3% F- score on multiple genres.
