Embedding restaurant reviews

One common classification task that embeddings are great for is sentiment analysis. In this and the following exercises, you'll navigate through the workflow of performing sentiment analysis using embeddings.

You've been provided with a small sample of restaurant reviews, stored in reviews, and sentiment labels stored in sentiments:

sentiments = [{'label': 'Positive'},
              {'label': 'Neutral'},
              {'label': 'Negative'}]

reviews = ["The food was delicious!",
           "The service was a bit slow but the food was good",
           "Never going back!"]

You'll use zero-shot classification to classify the sentiment of these reviews by embedding the reviews and class labels.

The create_embeddings() function you created previously is also available to use.

Instructions

  • Copy your API key and provide it to the OpenAI client.
  • Create a list of class descriptions from the labels in the sentiments dictionary using a list comprehension.
  • Embed class_descriptions and reviews using the create_embeddings() function.
