This topic covers a variety of use cases for transformation pipelines using Copilot. These examples showcase Copilot's capacity to streamline workflows, enhance collaboration, and drive informed decision making with data.


Example 1: Analyzing profit margins for high-margin customers

In this scenario, let's imagine we're working with a company called XYZ.

We've already calculated profit by customer and product, but now we want to delve deeper and determine the profit margin on these items to identify our highest margin customers.

Calculate profit margin

  • Objective: Calculate profit margin and store the result in a new column called "margin."
  • Action: Use Copilot to add a Calculator component for profit margin.
  • Component used: Calculator.
  • Outcome: A new column "margin" is added to the data table.

Process

Our written prompt to Copilot is "Calculate profit margin and store the result in a new column called "margin."" Copilot will then identify the structure of the data and choose the Calculator component. Sampling the data then shows the new "margin" column for profit margins.

Sample data input:

+-----------+---------+--------+------------------+
| Customer  | Product | Profit | Transaction Date |
+-----------+---------+--------+------------------+
| Cust1     | ProdA   | $100   | 2021-11-10       |
| Cust2     | ProdB   | $150   | 2022-01-15       |
| Cust3     | ProdC   | $200   | 2022-03-15       |
| Cust4     | ProdD   | $250   | 2023-05-22       |
+-----------+---------+--------+------------------+

Sample Output after calculating profit margin:

+-----------+---------+--------+--------+------------------+
| Customer  | Product | Profit | Margin | Transaction Date |
+-----------+---------+--------+--------+------------------+
| Cust1     | ProdA   | $100   | 25%    | 2021-11-10       |

Example 3: Analyzing customer feedback with Copilot and Snowflake Cortex components

In this scenario, we want to use Snowflake Cortex components to manage and respond to customer reviews. This example showcases translating reviews, performing sentiment analysis on those reviews, and generating automated responses based on sentiment scores.

Initial setup

First we provide Copilot with some context: "You are a data engineer working for a hotel company that collects customer reviews for the hotel's booking system."

Our review data is stored in a table, and the reviews are written in French.

Sample Data Input:

+-----------+-----------------------------------------------------+
| User      | Review_text                                         |
+-----------+-----------------------------------------------------+
| User A    | "Produit excellent, très convivial !"               |
| User B    | "A besoin d'amélioration, trop de bugs."            |
| User A    | "J'aimerais voir plus de fonctionnalités ajoutées." |
| User C    | "Excellent service client."                         |
+-----------+-----------------------------------------------------+

Translate reviews

  • Objective: Translate customer reviews from French to English.
  • Action: Use Copilot to automatically identify and apply the appropriate transformation logic.
  • Component Used: Cortex Translate.
  • Outcome: A new column is added to the data table containing the translated reviews.

Process

Our prompt to Copilot is "Translate the review_text rows from French to English. Drop the input column." Copilot selects the Cortex Translate component and applies the logic to translate the input text from French to English. Sampling the data shows a new column with translated text in English. As per our prompt, Copilot has not included the input (French) column.

Sample output after translation:

+-----------+-------------------------------------------+
| User      | en_Review_text                            |
+-----------+-------------------------------------------+
| User A    | "Great product, very user-friendly!"      |
| User B    | "Needs improvement, too many bugs."       |
| User C    | "Would love to see more features added."  |
| User D    | "Excellent customer support."             |
+-----------+-------------------------------------------+

Sentiment analysis

Objective: Determine the sentiment of the reviews to gauge customer satisfaction. Action: Use Copilot to apply a sentiment analysis transformation. Component Used: Cortex Sentiment. Outcome: A new column is added with sentiment scores for each review.

Process

Our prompt to Copilot is "Calculate the sentiment score of each review in "en_Review_text"." Copilot selects the Cortex Sentiment component and applies logic to calculate sentiment by analyzing each review. Sampling the data shows sentiment scores, indicating whether reviews are positive (1), negative (-1), or neutral (0).

Sample Output After Sentiment Analysis:

+-----------+----------------------------------------------------------+
| en_Review_text                            | sentiment_en_Review_text |
+-----------+-------------------------------|--------------------------+
|"Great product, very user-friendly!"       | 0.86195534               |
| "Needs improvement, too many bugs."       | -0.075002715             |
| "Would love to see more features added."  | 0.31447184               |
| "Excellent customer support."             | 0.78951025               |
+-----------+----------------------------------------------------------+

Automated apology email generation

Objective: Automatically generate apology emails for negative reviews to improve customer service. Action: Use Copilot to create a condition-based response mechanism. Components Used: Filter, Cortex Completions. Outcome: Automated generation of personalized apology emails for reviews with low sentiment scores.

Process

Our prompt to Copilot is "For sentiment scores lower than 0, generate a paragraph to apologize to the customer based on the content of their review." Copilot adds a Filter component to filter rows where the sentiment score is less than 0, then Copilot uses a Cortex Completions component to invoke a large language model (LLM) to craft apology emails based on user reviews.

Sample output after apology generation:

+-------------------------------------+--------------------------+--------------------+
| en_Review_text                      | sentiment_en_Review_text | completion_result  |
+-------------------------------------+--------------------------+--------------------+
| "Needs improvement, too many bugs." | -0.07575456              | "Dear customer..." |
