I stumbled over SpaCy when looking for something to extract key words and numbers from sentences, however it looked a bit daunting and/or overkill. Think recipes or similar, turning "take three tablespoons of sugar" into [3, 'tablespoons', 'sugar'] or similar.
Should I give it another shot or are there libraries more suited for this than just plain regexp galore?
