Installation

You can set up this SDK either via running $ pip install refinery-python-sdk, or by cloning this repository and running $ pip install -r requirements.txt.

Usage

Creating a Client object

Once you installed the package, you can create a Client object from any Python terminal as follows:

from refinery import Client

user_name = "your-username" # this is the email you log in with
password = "your-password"
project_id = "your-project-id" # can be found in the URL of the web application

client = Client(user_name, password, project_id)
# if you run the application locally, please use the following instead:
# client = Client(username, password, project_id, uri="http://localhost:4455")

The project_id can be found in your browser, e.g. if you run the app on your localhost: http://localhost:4455/app/projects/{project_id}/overview

Alternatively, you can provide a secrets.json file in your directory where you want to run the SDK, looking as follows:

{
    "user_name": "your-username",
    "password": "your-password",
    "project_id": "your-project-id"
}

Again, if you run on your localhost, you should also provide "uri": "http://localhost:4455". Afterwards, you can access the client like this:

client = Client.from_secrets_file("secrets.json")

With the Client, you easily integrate your data into any kind of system; may it be a custom implementation, an AutoML system or a plain data analytics framework 🚀

Fetching labeled data

Now, you can easily fetch the data from your project:

df = client.get_record_export(tokenize=False)
# if you set tokenize=True (default), the project-specific 
# spaCy tokenizer will process your textual data

Alternatively, you can also just run refinery pull in your CLI given that you have provided the secrets.json file in the same directory.

The df contains both your originally uploaded data (e.g. headline and running_id if you uploaded records like {"headline": "some text", "running_id": 1234}), and a triplet for each labeling task you create. This triplet consists of the manual labels, the weakly supervised labels, and their confidence. For extraction tasks, this data is on token-level.

An example export file looks like this:

[
  {
    "running_id": "0",
    "Headline": "T. Rowe Price (TROW) Dips More Than Broader Markets",
    "Date": "Jun-30-22 06:00PM\u00a0\u00a0",
    "Headline__Sentiment Label__MANUAL": null,
    "Headline__Sentiment Label__WEAK_SUPERVISION": "Negative",
    "Headline__Sentiment Label__WEAK_SUPERVISION__confidence": "0.6220"
  }
]

In this example, there is no manual label, but a weakly supervised label "Negative" has been set with 62.2% confidence.

Fetching lookup lists

In your project, you can create lookup lists to implement distant supervision heuristics. To fetch your lookup list(s), you can either get all or fetch one by its list id.

list_id = "your-list-id"
lookup_list = client.get_lookup_list(list_id)

The list id can be found in your browser URL when you're on the details page of a lookup list, e.g. when you run on localhost: http://localhost:4455/app/projects/{project_id}/knowledge-base/{list_id}.

Alternatively, you can pull all lookup lists:

lookup_lists = client.get_lookup_lists()

Upload files

You can import files directly from your machine to your application:

file_path = "my/file/path/data.json"
upload_was_successful = client.post_file_import(file_path)

We use Pandas to process the data you upload, so you can also provide import_file_options for the file type you use. Currently, you need to provide them as a \n-separated string (e.g. "quoting=1\nsep=';'"). We'll adapt this in the future to work with dictionaries instead.

Alternatively, you can refinery push <path-to-your-file> via CLI, given that you have provided the secrets.json file in the same directory.

Make sure that you've selected the correct project beforehand, and fit the data schema of existing records in your project!

Adapters

Rasa

refinery is perfect to be used for building chatbots with Rasa. We've built an adapter with which you can easily create the required Rasa training data directly from refinery.

To do so, do the following:

from refinery.adapter import rasa

rasa.build_intent_yaml(
  client,
  "text",
  "__intent__WEAK_SUPERVISION"
)

This will create a .yml file looking as follows:

nlu:
- intent: check_balance
  examples: |
    - how much do I have on my savings account
    - how much money is in my checking account
    - What's the balance on my credit card account

If you want to provide a metadata-level label (such as sentiment), you can provide the optional argument metadata_label_task:

from refinery.adapter import rasa

rasa.build_intent_yaml(
  client,
  "text",
  "__intent__WEAK_SUPERVISION",
  metadata_label_task="__sentiment__WEAK_SUPERVISION"
)

This will create a file like this:

nlu:
- intent: check_balance
  metadata:
    sentiment: neutral
  examples: |
    - how much do I have on my savings account
    - how much money is in my checking account
    - What's the balance on my credit card account

And if you have entities in your texts which you'd like to recognize, simply add the tokenized_label_task argument:

from refinery.adapter import rasa

rasa.build_intent_yaml(
  client,
  "text",
  "__intent__WEAK_SUPERVISION",
  metadata_label_task="__sentiment__WEAK_SUPERVISION",
  tokenized_label_task="text__entities__WEAK_SUPERVISION"
)

This will not only inject the label names on token-level, but also creates lookup lists for your chatbot:

nlu:
- intent: check_balance
  metadata:
    sentiment: neutral
  examples: |
    - how much do I have on my [savings](account) account
    - how much money is in my [checking](account) account
    - What's the balance on my [credit card account](account)
- lookup: account
  examples: |
    - savings
    - checking
    - credit card account

Please make sure to also create the further necessary files (domain.yml, data/stories.yml and data/rules.yml) if you want to train your Rasa chatbot. For further reference, see their documentation.

What's missing?

Let us know what open-source/closed-source NLP framework you are using, for which you'd like to have an adapter implemented in the SDK. To do so, simply create an issue in this repository with the tag "enhancement".

Roadmap

• Register heuristics via wrappers
• Up/download zipped projects for versioning via DVC
• Add project upload
• Fetch project statistics

If you want to have something added, feel free to open an issue.
