We present an algorithm for generating referring expressions in open domains. Existing algorithms work at the semantic level and assume the avail- ability of a classi cation for attributes, which is only feasible for restricted domains. Our alterna- tive works at the realisation level, relies on Word- Net synonym and antonym sets, and gives equiva- lent results on the examples cited in the literature and improved results for examples that prior ap- proaches cannot handle. We believe that ours is also the rst algorithm that allows for the incremen- tal incorporation of relations. We present a novel corpus-evaluation using referring expressions from the Penn Wall Street Journal Treebank.
