Chatdata

ChatData is a Python-based web application for asking natural-language questions about a MyScale-hosted knowledge base or uploaded documents. It uses LangChain retrieval and MyScale vector search to find relevant material and present answers through a Streamlit interface.

Practical overview

When it fits

Use ChatData when you want a chat-style interface for searching reference collections or your own uploaded documents, especially where semantic search and structured filters are both useful.

Who it is for

  • Researchers and students exploring academic papers and reference material.
  • Teams or individuals who want to query an uploaded document collection.

Documented uses

  • Ask natural-language questions across Wikipedia and arXiv material hosted through MyScale.
  • Create a personal knowledge base from uploaded documents and retrieve relevant information.
  • Use structured metadata such as dates or string arrays to filter retrieval queries.
Before you choose

Requirements & limits

The repository provides a local setup path and a Hugging Face Spaces link. The local quickstart requires an OpenAI key.

  • The project combines LangChain retrieval with MyScale vector search and SQL-based filtering.
  • Its README documents Wikipedia and arXiv knowledge bases as well as user-uploaded documents.
  • The repository is licensed under MIT.
  • The README cautions that some self-query retriever features were still being improved and were not yet merged.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up ChatData locally

Prepare and launch the Streamlit app from its repository.

Before you start

  • Python 3
  • An OpenAI key
  • The ChatData repository and its app dependencies

Steps

  1. Change to the app/ directory.

  2. Create and activate a Python virtual environment.

  3. Install dependencies from requirements.txt.

  4. Copy .streamlit/secrets.example.toml to .streamlit/secrets.toml and add the OpenAI key.

  5. Start the app with python3 -m streamlit run app.py.

Expected outcome

The repository's quickstart launches the ChatData Streamlit app locally.

Guide limitations

  • The quickstart documents setup and launch, but does not provide a complete guide to configuring a separate MyScale database or uploading a document collection.
