To take a dependency on Adapt, it's recommended to use virtualenv and pip to install source from from github.
$ virtualenv myvirtualenv $ . myvirtualenv/bin/activate $ pip install -e git+https://github.com/mycroftai/adapt#egg=adapt-parser
Executable examples can be found in the examples folder.
The Adapt Intent Parser is a flexible and extensible intent definition and determination framework. It is intended to parse natural language text into a structured intent that can then be invoked programatically.
In this context, an Intent is an action the system should perform. In the context of Pandora, we’ll define two actions: List Stations, and Select Station (aka start playback)
With the Adapt intent builder:
list_stations_intent = IntentBuilder('pandora:list_stations')\ .require('Browse Music Command')\ .build()
For the above, we are describing a “List Stations” intent, which has a single requirement of a “Browse Music Command” entity.
play_music_command = IntentBuilder('pandora:select_station')\ .require('Listen Command')\ .require('Pandora Station')\ .optionally('Music Keyword')\ .build()
For the above, we are describing a “Select Station” (aka start playback) intent, which requires a “Listen Command” entity, a “Pandora Station”, and optionally a “Music Keyword” entity.
Entities are a named value. Examples include: Blink 182 is an Artist The Big Bang Theory is a Television Show Play is a Listen Command Song(s) is a Music Keyword
For my Pandora implementation, there is a static set of vocabulary for Browse Music Command, Listen Command, and Music Keyword (defined by me, a native english speaker and all-around good guy). Pandora Station entities are populated via a list stations API call to Pandora. Here’s what the vocabulary registration looks like.
def register_vocab(entity_type, entity_value): # a tiny bit of code def register_pandora_vocab(emitter): for v in ["stations"]: register_vocab('Browse Music Command', v) for v in ["play", "listen", "hear"]: register_vocab('Listen Command', v) for v in ["music", "radio"]: register_vocab('Music Keyword', v) for v in ["Pandora"]: register_vocab('Plugin Name', v) station_name_regex = re.compile(r"(.*) Radio") p = get_pandora() for station in p.stations: m = station_name_regex.match(station.get('stationName')) if not m: continue for match in m.groups(): register_vocab('Pandora Station', match)
