Abstract:     A statistical language model for inflected languages, having very large vocabularies, is generated by splitting words into stems, prefixes and endings, and deriving trigrams for the stems, ending and prefixes. The statistical dependence of endings and prefixes from each stem is also obtained, and the resulting language model is a weighted sum of these scores.

First Claim:
Show all 21 claims
We claim:     1. A method for generating a language model, comprising:
  • providing to a classifier a corpus of words having a given sequence;
  • performing a plurality of transformations on the words in the corpus, while preserving the given sequence, to generate a plurality of classes, each of the plurality of classes having a different stream of word components associated therewith, said different stream of word components being generated in accordance with one of the transformations;
  • estimating statistical data representing each of the classes; and
  • weighting and combining the statistical data to form the language model.
