Snack2Graph

Exploring Knowledge Graphs

An application that parses unstructured text and constructs a Knowledge Graph with a rich web of inter-connected relationships using FalkorDB.

In essence, this tool snacks stuff and outputs a knowledge graph of what it snacked on.

This is purely for exploration purposes.

Setup

Install uv (see the doc site), our Python package manager of choice. Here is a quick start guide of uv that contains some basic features.

Verify your setup by running the command below.

uv run python src/main.py --help

Tip: Whenever this command is run, uv automatically installs the needed packages from the lockfile into your .venv project environment and even creates it if hasn't been yet (see the doc site about 'project environment' for more info).

Running the CLI

The project includes a CLI for processing text files. Show all available commands using help.

uv run python src/main.py --help

A successful run should look like:

Usage: main.py [OPTIONS] COMMAND [ARGS]...
