How the Project Works

The project accomplishes its tasks through a series of steps shared below. Make sure you give it a quick read before proceeding to the next step where we explore the repository.

1 - Realtime Indexing:

  • Sourcing data: A script called discounts-data-generator.py mimics real-time data from external sources. It creates or updates a file named discounts.csv with random data. Alongside this, a scheduled task (cron job) using Python Crontab runs every minute to fetch the latest data from Rainforest API. Crontab is a time-based job scheduler.
  • Giving the option to choose particular data source(s): With the Streamlit UI provided, either select Rainforest API as a data source or upload a CSV through the UI file-uploader. It then maps each row into a JSONline schema for better managing large data sets. This format helps in managing large datasets by representing each row as a separate JSON object
  • Chunking: The documents are divided into shorter sections for them to be converted into vector embeddings.
  • Embedding of data source: These shorter sections are processed through the OpenAI API to generate embeddings.
  • Real-time Vector Indexing: An index is created based on these embeddings to facilitate quick searching later on.

2 - Query (Prompt) Embedding and Retrieval

  • Query Embedding: For any question asked by the user, an embedding is generated using the OpenAI API for embeddings, i.e., text-embedding-ada-002.
  • Retrieving: The system compares the vector embedding of the query/prompt and the vector embedding of the data source to find the most relevant information.

3 - Prompt Augmentation and Answer Generation

  1. The query/prompt and the most relevant sections of data are packaged into a message within the token limit.
  2. Get an Answer from GPT: This message is sent to gpt-3.5-turbo, which then provides an answer.
