In recent years (Belz et al., 2010) there has been a shift towards what we term "Open Domain Referring Expression Generation," (OD REG), that is, a REG task where the properties come from a folksonomy, a large-scale volunteer-built ontology.
we are interested in changing anaphoric references for entities appearing in sentences drafted from different documents, as done in multi-document summarization (Advaith et al., 2011).
