What is it?

Each vendor of soccer data uses its own unique format to describe the course of a game. Hence, software written to analyze this data has to be tailored to a specific vendor and cannot be used without modifications to analyze data from other vendors. Kloppy is a Python package that addresses the challenges posed by the variety of data formats and aims to be the fundamental building block for processing soccer tracking and event data. It provides (de)serializers, standardized data models, filters, and transformers which make working with tracking and event data from different vendors a breeze.

Main features

Here are just a few of the things that kloppy does well:

Loading data

  • Load public datasets to get started right away
  • Understandable standardized data models for tracking and event data
  • Out-of-the-box (de)serializing tracking and event data from different vendors into standardized models and vice versa

Processing data

  • Flexibly transform a dataset's pitch dimensions from one format to another (e.g., from OPTA's 100x100 to TRACAB meters)
  • Transform the orientation of a dataset (e.g., from TRACAB fixed orientation to "Home Team" orientation)

Pattern matching

  • Search for complex patterns in event data
  • Use kloppy-query to export fragments to XML file
