GreenKey Scribe Discovery SDK Build StatusFINOS - Active

Powerful NLP API for human conversations


The Discovery SDK allows you to write logic-based interpreters, and let GreenKey's Discovery engine use machine learning to identify intents and extract entities.

You can use your Discovery interpreter to power several voice- and chat-driven workflows

Read more about Discovery on our blog or checkout the full documentation

The GreenKey Discovery SDK is hosted by the Voice Program of the Fintech Open Source Foundation (FINOS). If you are a company interested in the evolution of open standards, interoperability, and innovation in the financial services sector, please consider joining FINOS.

Overview

  1. Quickstart

    • Step through the 'digit' interpreter example.
  2. Customization

    • Customize your own interpreter.
  3. Advanced Examples and Documentation

    • Transcribing voice audio files with Scribe and using the Discovery engine.

1. Quickstart

Requirements

  • Docker 17+ (or Discovery Binaries)
  • Python 3 with pip

Dependencies

To ensure your dependencies install correctly, we recommend that you upgrade your setuptools before proceeding further.

python3 -m pip install --upgrade setuptools

Now you are ready to install the required dependencies with pip. This will provide you with the packages needed to run the test_discovery.py script (see the 'digit' example below), as well as the Discovery CLI.

python3 -m pip install -r requirements.txt

Using Compiled Binary Files

If you are unable to use Docker, contact us to obtain compiled binary files for Discovery. Simply place the binaries directory into the SDK directory before running test_discovery.py. The test script will automatically detect the binaries directory and use that instead of a Docker image.

Make sure not to change the name of the binaries file when you move it. You should end up with a structure like the following for the test_discovery.py script to work.

└───greenkey-discovery-sdk
    └───discovery_binaries_windows_10_64bit__python37_64bit
    └───examples
    └───gk_cli
    │   discovery_config.py
    │   README.md
    │   test_discovery.py

Obtaining Credentials

Contact us to obtain credentials to obtain the Discovery Docker container from our repository and launch the Discovery engine.

Discovery Examples Directory Overview

Each discovery example contains a folder named custom, which in turn contains the required definitions.yaml file. Some examples contain a schemas key in the definitions.yaml file to customize the return json. They also contain example scripts to see how the particular configuration will detect entities.

examples
└── digit
    ├── custom
    │   └── definitions.yaml
    ├── send_transcript_to_discovery.sh
    └── tests.txt

The 'digit' Interpreter Example

  1. Test cases for the room dialing example are in examples/digit/tests.txt
intent_whitelist: digit

test: dial number
transcript: please dial eight
room_number: 8

test: dial number
transcript: press one eight
room_number: 1
...
  1. The definition file, examples/digit/custom/definitions.yaml, contains examples that match the tests
entities:
  room_number:
    - "@num"
intents:
  digit:
    examples:
      - "please select @num to speak to the operator"
      - "to change your order press @room_number"
      - "if this is an emergency dial @room_number"
      - "for animal control services press @room_number"

where "digit" is the name of the intent and the entities value ("room_number") match entities in tests.txt.

2. Customization

Creating a custom project can be done by following the structure of an existing example found in the examples folder. Refer to the wiki for further information on customization

3. Deploying

Check out our deployment documentation for full details on deploying Discovery.
