Corpus based preposition selection - HOWTO

From Apertium
Jump to navigation Jump to search

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: apertium.svn.sourceforge.net/svnroot/apertium/branches/gsoc2012/fpetkovski/morph-parser/

Extracting training data for your classifier

For the purpose of extracting training data for your classifier, you can use the preposition-extraction tool.
