Palavreado

A dead-simple keyword based intent parser

Example

from palavreado import IntentContainer, IntentCreator

container = IntentContainer()

# keywords
intent = IntentCreator("hello"). \
    require('hello', ['hello', 'hi', 'how are you', "what's up"]).\
    optionally("world", ["world"])
container.add_intent(intent)

# regex
rx = r'\b(at|in|for) (?P<Location>.*)'
intent = IntentCreator("time_in_location"). \
    require_regex("Location", rx)\
    .require("time", ["time"])
container.add_intent(intent)

# keyword extraction patterns
intent = IntentCreator("buy"). \
    require_autoregex('item',
                      ['buy {item}', 
                       'purchase {item}', 
                       'get {item}',
                       'get {item} for me'])
container.add_intent(intent)
