Abstract
A large number of wording choices naturally occurring in English sentences cannot be accounted for on semantic or syntactic grounds. They represent arbitrary word usages and are termed collocations. In this paper, we show how collocations can enhance the task of lexical selection in language generation. Previous language generation systems were not able to account for collocations for two reasons: they did not have the lexical information in compiled form and the lexicon formalisms available were not able to handle the variations in collocational knowledge. We describe an implemented generator, Cook, which uses a wide range of collocations to produce sentences in the stock market domain. Cook uses a flexible lexicon containing a range of collocations, from idiomatic phrases to word pairs that were compiled automatically from text corpora using a lexicographic tool, Xtract. We show how Cook is able to merge collocations of various types to produce a wide variety of sentences.
