Purpose

This repository houses work completed by Delta Analytics teams as part of their 2018 and 2019 commitments to the Open Media Foundation. The project has involved two components:

1. Building a model to categorize transcribed captions of local government meetings into a broad set of topics (2018)
2. Developing a prototype visualization and search tool that leverages the categorization model (2019)

Usage

To run the app locally, run ./run_local.sh in a terminal. Note that the backend API is fairly slow, so it may take some time to load sessions into view.
