QA Slack Bot - MrsStax

Introduction

This application is a Slack Bot that uses Langchain and OpenAI's GPT3 language model to provide domain specific answers. You provide the documents.

This app includes the OpenStax textbook "Principles of Macroeconomics 3e" for demonstration purposes.

Principles of Macroeconomics 3e is licensed under a Creative Commons Attribution 4.0 International (CC BY) license, which means that you can distribute, remix, and build upon the content, as long as you provide attribution to OpenStax and its content contributors.

If you left the two original files (Macroeconomics3e-WEB.pdf, pdf1.txt) in your docs directory you should be able to ask your bot economics related questions. For example.

• Q1. Residents of the town of Smithfield like to consume hams, but each ham requires 10 people to produce it and takes a month. If the town has a total of 100 people, what is the maximum amount of ham the residents can consume in a month?

• Q2. Why might Belgium, France, Italy, and Sweden have a higher export to GDP ratio than the United States?

• Q3. What is dumping? Why does prohibiting it often work better in theory than in practice?

12. Your vector database needs to be re-indexed each time you add or remove documents from your docs folder. To do this simply run python ingest.py.
