Surface realisers divide into those used in generation (NLG geared realisers) and those mirroring the parsing process (Reversible re- alisers). While the first rely on grammars not easily usable for parsing, it is unclear how the second type of realisers could be param- eterised to yield from among the set of pos- sible paraphrases, the paraphrase appropri- ate to a given generation context. In this pa- per, we present a surface realiser which com- bines a reversible grammar (used for pars- ing and doing semantic construction) with a symbolic means of selecting paraphrases.
