• Channels
• NLU

Installation

# optional: create a virtual environment
python3 -m venv myvenv
source myvenv/bin/activate

# install agt
pip3 install agt

Additional dependecies

You may want to install dependencies to connect to channels such as telegram and discord or share components on cocohub.

Available dependecies

• discord - to connect your bot/component to discord
• telegram - to connect your bot/component to telegram
• msbf - to connect your bot/component to microsoft bot framework
• vendor - publish component on cocohub
• dsl - Hy DSL for nicer syntax when building components/nlu

Examples:

pip install agt[telegram]
# or for multiple dependecies
pip install agt[telegram,dsl]

Getting Started

Create your first bot

Agent components are python coroutines (note the async def)

We take state as the first parameter - which is an object that allow us to interact with the environment the component/bot is running on

async def mybot(state):
    # state.user_input() waits for the next user input
    user_input = await state.user_input()

    # state.say sends a response
    await state.say(user_input)

Paste this code in a file called example.py

Try it in the terminal

python3 -m agt example.mybot

Channels

Connecting to channels is easy and just requires using regular Agent components

Telegram

Make sure to install agt with telegram support - pip install agt[telegram]

Create a new bot and get telegram token from Telegram botfather using this guide: https://core.telegram.org/bots#6-botfather

export TELEGRAM_TOKEN=<Your telegram bot token>
python3 -m agt.channels.telegram example.mybot

Discord

Make sure to install agt with discord support - pip install agt[discord]

Create a new bot account and get a token using this guide: https://discordpy.readthedocs.io/en/latest/discord.html

export DISCORD_KEY=<Your discord bot token>
python3 -m agt.channels.discord example.mybot

Microsoft bot framework

Make sure to install agt with microsoft bot framework support - pip install agt[msbf]

export MicrosoftAppId=<Your bot Microsft App Id>
export MicrosoftAppPassword=<Your bot Microsoft App Password>
python3 -m agt.channels.msbf example.mybot

Basic Language Understanding

Inside agt.nlu we have simple patterns to regex compiler to perform basic understanding tasks

Compile simple word patterns to regex

Some Examples:

intent = Intent(
    Pattern("the", "boy", "ate", "an", "apple")
)
assert intent("the boy ate an apple") == True
assert intent("the boy ate an orange") == False

intent = Intent(
    Pattern("the", "boy", "ate", "an", AnyWords(min=1, max=1))
)
assert intent("the boy ate an apple") == True
assert intent("the boy ate an orange") == True

intent = Intent(
    Pattern("the", Words("boy", "girl"), "ate", "an", AnyWords(min=1, max=1))
)
assert intent("the boy ate an apple") == True
assert intent("the boy ate an orange") == True
assert intent("the girl ate an orange") == True
assert intent("the girl ate a banana") == False

intent = Intent(
    Pattern("the", ("boy", "girl"), "ate", WordsRegex(r"an?"), AnyWords(min=1, max=1))
)
assert intent("the boy ate an apple") == True
assert intent("the boy ate an orange") == True
assert intent("the girl ate an orange") == True
assert intent("the girl ate a banana") == True
assert intent("a nice boy ate an apple") == False

intent = Intent(
    Pattern(WILDCARD, Words("boy", "girl"), "ate", WordsRegex(r"an?"), AnyWords(min=1, max=1))
)
assert intent("a nice boy ate an apple") == True

Pattern takes sentence elements and translate each one to optmized regular expression.

Intent groups multiple patterns so if any of the patterns match the intent evals to True
