Research output: Chapter in Book/Report/Conference proceedingPublished conference contribution


We present an algorithm for generating referring expressions in open domains. Existing algorithms work at the semantic level and assume the availability of a classication for attributes, which is only feasible for restricted domains. Our alternative works at the realisation level, relies on Word-Net synonym and antonym sets, and gives equivalent results on the examples cited in the literature and improved results for examples that prior approaches cannot handle. We believe that ours is also the first algorithm that allows for the incremental incorporation of relations. We present a novel corpus-evaluation using referring expressions from
the Penn Wall Street Journal Treebank.
