qary

The qary package is both a chatbot framework and a working "reference implementation" virtual assistant that actually assists! Most bots manipulate you to make money for their corporate masters. With qary, you can build your bot to protect you and amplify your intelligence and prosocial instincts.

qary was conceived as part of NLP in Action book, is maintained by an active developer community and is supported by San Diego Python User Group (see talk presentations here and in docs/.

Install

Package install

qary package can be installed from PyPi by running:

pip install qary

Developer install

First retrieve a copy of the source code for qary:

git clone git@gitlab.com:tangibleai/qary
cd qary

Then, install and use the conda python package manager within the Anaconda software package. A cross-platform package and python environment manager like conda is especially important if your operating system is not an open standard like Linux.

conda update -n base -c defaults conda
conda create -n qaryenv 'python>=3.6.5,<3.8'
conda env update -n qaryenv -f environment.yml
source activate qaryenv
pip install --editable .

Usage

$ qary --help
usage: bot [-h] [--version] [--name STR] [-p] [-b STR] [-v] [-vv] [words [words ...]]

Running qary with a single statement/query

You can run bot just like any other command line app, giving it your statement/query as an argument.

$ qary -b glossary -q  # -q quiets the logging messages, `-b glossary` loads the glossary bot
YOU: what is an allele
qary: A variant form of a given gene, a version of a known mutation at the same place as the original unmodified gene within a chromosome.

Running qary in dialog mode

$ qary [-b <personality1>,<personality2>] ...
# ... (logging messages)
YOU: When was Barack Obama born?
# ... (logging messages)
qary: August 4, 1961

qary personalities

qary's probabilistic conversation manager chooses a reply from the possiblities generated by the different personalities:

  • qa (qa_bots.py): BERT and ALBERT Wikipedia Question Answering (WikiQA reading comprehension tests)
  • faq (faq_bots.py): answers to frequently asked questions using data/faq/*.yml
  • glossary (glossary_bots.py): definitions from glossary yml files in data/faq/glossary-*.yml
  • pattern (pattern_bots.py): regex patterns and greeting templates
  • eliza (eliza_bots.py): a python port of the ELIZA therapist bot

Configuring default personalities

By default, qary runs with qa personality. Check out the config file in qary.ini or $ bot -h to change the default bot personalities loaded for your own custom bot.

Approach

qary's hybrid chatbot framework allows you to combine 4 approaches to give you state-of-the-art capability to answer questions and carry on a conversation:

  1. search: chatterbot, will
  2. pattern matching and response templates: Alexa, AIML
  3. generative deep learning: robot-bernie, movie-bot
  4. grounding: snips

It's all explained in detail at NLP in Action.
