SAT Q&A: Question Answering System based on Google Palm LLM and langchain for SAT questions on world_history and us_history

This is an end to end LLM project based on Google Palm and Langchain. I have built a Q&A system for students preparing for SAT examination. SAT is a standardized test widely used for college admissions in the United States. This system will provide a streamlit based user interface for students where they can ask questions and get answers. Currently the application is focused on questions related to us_history and world_history

Interface Demo

Project Highlights

  • Use a real CSV file of SAT Question and Answers on us_history and world_history.
  • Student who are attempting the SAT exam refer previous year paper for practice.
  • I built an LLM based question and answer system that can reduce the workload of searching answers.
  • Students should be able to use this system to ask questions directly and get answers within seconds.

Technologies Used:

  • Langchain + Google Palm: LLM based Q&A
  • Streamlit: UI
  • Huggingface instructor embeddings: Text embeddings
  • FAISS: Vector database

Installation

  1. Clone this repository to your local machine using:
  git clone /~https://github.com/MaruthiKo/SAT_QA.git
  1. Navigate to the project directory:
  cd SAT_QA
  1. Install the required dependencies using pip:
  pip install -r requirements.txt
  1. Acquire an api key through makersuite.google.com and put it in .env file
  GOOGLE_API_KEY="your_api_key_here"

Usage

  1. Run the Streamlit app by executing:
streamlit run main.py
  1. The web app will open in your browser.
    • To create knowledge base uncomment the line in langchain_helper, create vector_db. It will take some time before knowledgebase is created so please wait.
    • Once knowledge base is created you will see a directory called faiss_index in your current folder.
    • Now you are ready to ask questions. Type your question in Question box and hit Enter
