An example of inventory counting using SpaCy.io NLP library. Meant to show how to instantiate Spacy's English class, and allow reusability by reloading the main module.
In the future, a better implementation of this library would be to apply machine learning to each query and learn what to classify as the quantitative statement (55 kgs OF), vs the actual item of count (how likely is a preposition object to be the item of count if x,y,z qualifications appear in the statement).
