Corpus based preposition selection - HOWTO

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:
