Hello HN, I'm the original author of Duckling (with @blandinw). As usual, always happy to get feedback and suggestions.

I must say it looks very eat from the point of view of usability. Are the training data sets open? Do you see feasible for small app coders (who don’t have thousands of examples to train) to use Duckling as more or less NLP parser without getting too much deep into the NLP and AI theory?

Are the trained sets mean to be used by different client code or languages?
