Dart Rankings

This repository contains code for a side project of mine. I crawl publicly available results of darts matches in my local area and use them to assign a skill level to all players, similar to the chess ELO system.

I use the TrueSkill system to evaluate a player's performance to get ratings that "converge" with only a handful of matches. With decent ratings, it is possible to calculate the probability of the outcome of any match. A short summary of how TrueSkill works can be found here.

TODOs

• Currently building a node.js/express app to display leaderboards
• Analysis of rankings and distribution of rankings per ligue
• Player badges for streaks and extraordinary accomplishments

Usage

Crawl data: Start selenium in docker:

docker run -d -p 4444:4444 -p 7900:7900 --shm-size="2g" -e SE_NODE_MAX_SESSIONS=3 selenium/standalone-firefox:4.17.0-20240123

Then execute the script to crawl concurrently:

python scripts/crawl_concurrent.py --path [PATH] --season 202X --date [YYYY-MM-DD] --associations DBH NDV

Create database and populate it :

python src/schema.py --filename [DB_PATH] && \
python src/insert_data.py -db [DB_PATH] --data [DATA_PATH]

Beware: Powershell does not handle wildcards, pass data as --data $(ls .\data\2023\*55.json | % {$_.FullName})
