The general algorithm for performing corpus based preposition selection is as follows:

  • Download a parallel corpus
  • Extract patterns which contain prepositions from the source-language corpus
  • Align the patterns to their translations in the target-language corpus
  • Extract the features and label (the correct preposition from the target-language corpus) for classification.
  • Train a model
  • Use the trained model in the pipeline

The general toolkit for performing these tasks can be found here:
