Abstract
</SectionTitle>
    <Paragraph position="0"> In this paper, we present a stochastic language modeling tool which aims at retrieving variable-length phrases (multigrams), assuming bigram dependencies between them. The phrase retrieval can be intermixed with a phrase clustering procedure, so that the language data are iteratively structured at both a paradigmatic and a syntagmatic level in a fully integrated way. Perplexity results on ATR travel arrangement data with a bi-multigram model (assuming bigram correlations between the phrases) come very close to the trigram scores with a reduced number of entries in the language model. Also the ability of the class version of the model to merge semantically related phrases into a common class is illustrated. null</Paragraph>
