The Ingredient Parser package is a Python package for parsing structured information out of recipe ingredient sentences.
Documentation on using the package and training the model can be found at https://ingredient-parser.readthedocs.io/en/latest/.
Install the package using pip
python -m pip install ingredient-parser-nlp
Import the parse_ingredient
function and pass it an ingredient sentence.
>>> from ingredient_parser import parse_ingredient
>>> parse_ingredient("3 pounds pork shoulder, cut into 2-inch chunks")
{'sentence': '3 pounds pork shoulder, cut into 2-inch chunks',
'quantity': '3',
'unit': 'pound',
'name': 'pork shoulder',
'comment': ', cut into 2-inch chunks',
'other': ''}
# Output confidence for each label
>>> parse_ingredient("3 pounds pork shoulder, cut into 2-inch chunks", confidence=True)
{'sentence': '3 pounds pork shoulder, cut into 2-inch chunks',
'quantity': '3',
'unit': 'pound',
'name': 'pork shoulder',
'comment': ', cut into 2-inch chunks',
'other': '',
'confidence': {'quantity': 0.9986,
'unit': 0.9967,
'name': 0.9535,
'comment': 0.9967,
'other': 0}}
The returned dictionary has the format
{
"sentence": str,
"quantity": str,
"unit": str,
"name": str,
"comment": str,
"other": str
}
The model provided in ingredient-parser/
directory has the following accuracy on a test data set of 25% of the total data used:
Sentence-level results:
Total: 9448
Correct: 8189
-> 86.67%
Word-level results:
Total: 54854
Correct: 52509
-> 95.73%
