An open-source chat bot program written in Python.
Project description
|Chatterbot: Machine learning in Python| # ChatterBot
ChatterBot is a machine-learning based conversational dialog engine
build in Python which makes it possible to generate responses based on
collections of known conversations. The language independent design of
ChatterBot allows it to be trained to speak any language.

An example of typical input would be something like this:
| **user:** Good morning! How are you doing?
| **bot:** I am doing very well, thank you for asking.
| **user:** You're welcome.
| **bot:** Do you like hats?
How it works
------------
An untrained instance of ChatterBot starts off with no knowledge of how
to communicate. Each time a user enters a statement, the library saves
the text that they entered and the text that the statement was in
response to. As ChatterBot receives more input the number of responses
that it can reply and the accuracy of each response in relation to the
input statement increase. The program selects the closest matching
response by searching for the closest matching known statement that
matches the input, it then returns the most likely response to that
statement based on how frequently each response is issued by the people
the bot communicates with.
Installation
------------
This package can be installed from
`PyPi <https://pypi.python.org/pypi/ChatterBot>`__ by running:
::
pip install chatterbot
Basic Usage
-----------
::
from chatterbot import ChatBot
chatbot = ChatBot("Ron Obvious")
# Train based on the english corpus
chatbot.train("chatterbot.corpus.english")
# Get a response to an input statement
chatbot.get_response("Hello, how are you today?")
Training data
=============
Chatterbot comes with a data utility module that can be used to train
chat bots. At the moment there is only English training data in this
module. Contributions of additional training data or training data in
other languages would be greatly appreciated. Take a look at the data
files in the
`chatterbot/corpus <https://github.com/gunthercox/ChatterBot/tree/master/chatterbot/corpus>`__
directory if you are interested in contributing.
::
# Train based on the english corpus
chatbot.train("chatterbot.corpus.english")
# Train based on english greetings corpus
chatbot.train("chatterbot.corpus.english.greetings")
# Train based on the english conversations corpus
chatbot.train("chatterbot.corpus.english.conversations")
**Corpus contributions are welcome! Please make a pull request.**
