TYTUŁ:     Generating and selecting grammatical paraphrases

Natural language has a high paraphrastic power yet not all paraphrases
are appropriate for all contexts. In this talk, I will present a TAG
based surface realiser which supports both the generation and the
selection of paraphrases. To deal with the combinatorial explosion
typical of such a task, a number of optimisations are introduced  in
a tabular, bottom-up surface realisation algorithm. I then show that
the resulting system favorably compares with similar proposals in
terms of efficiency and that it supports the selection of contextually
appropriate paraphrases.
