Next Steps

The cTAKES 23.6 0 Component Use Guide will help you to understand in great detail each of the cTAKES components that have been installed. In some cases you can learn how to improve the components. However, before you go on to process text in production you will need to consider dictionaries and models.

...

Some models included in cTAKES may not represent your data distribution well. If you want to build or train your own models, please read the cTAKES 23.6 0 Component Use Guide, particularly:

  • Training a sentence detector model
  • Training a Part of Speech (POS) tagger model (Building a model Obtaining training data)
  • Creating a Part of Speech (POS) tag dictionary (Building a tag dictionary)
  • Training a chunker model (Building a model - Prepare GENIA training data)
  • Training a dependency parser (Dependency Parser)
