Previous work on recognition is either limited to definite NPs based on heuristics evaluated on small datasets (Hahn et al., 1996; Vieira and Poesio, 2000) , or models it as a subtask of learning fine-grained IS (Rahman and Ng, 2012;<cite> Markert et al., 2012</cite>; Cahill and Riester, 2012) . Results within this latter framework for bridging have been mixed: We reported in<cite> Markert et al. (2012)</cite> low results for bridging in written news text whereas Rahman and Ng (2012) report high results for the four subcategories of bridging annotated in the Switchboard dialogue corpus by Nissim et al. (2004) .
