floodlight 0.3.1

A high-level framework for sports data analysis

floodlight

A high-level, data-driven sports analytics framework

floodlight is a Python package for streamlined analysis of sports data. It is designed with a clear focus on scientific computing and built upon popular libraries such as numpy or pandas.

Load, integrate, and process tracking and event data, codes and other match-related information from major data providers. This package provides a set of standardized data objects to structure and handle sports data, together with a suite of common processing operations such as transforms or data manipulation methods.

All implementations run completely provider- and sports-independent, while maintaining a maximum of flexibility to incorporate as many data flavours as possible. A high-level interface allows easy access to all standard routines, so that you can stop worrying about data wrangling and start focussing on the analysis instead!

Features

This project is still under development, and we hope to expand the set of features in the future. At this point, we provide core data structures, parsing functionality for major data providers, access to public data sets, data filtering, basic plotting routines and computational models.

Data-level Objects

• Tracking data
• Event data
• Pitch information
• Codes such as ball possession information
• Properties such as distances or advanced computations

Parser

• ChyronHego (Tracking data, Codes)
• DFL (Tracking data, Event data, Codes)
• Kinexon (Tracking data)
• Opta (Event data - F24 feeds)
• Second Spectrum (Tracking data)
• StatsPerform (Tracking data, Event data - also directly from URLs)
• StatsBomb (Event data)

Datasets

• EIGD-H (Handball tracking data)
• StatsBomb OpenData (Football event data)

Manipulation and Plotting

• Spatial transformations for all data structures
• Lowpass-filter tracking data
• Slicing and selection methods
• Plot pitches and tracking data

Models and Metrics

• Centroids
• Distances, Velocities, Accelerations
• Metabolic Power and Equivalent Distances
• Approximate Entropy

Installation

The package can be installed easily via pip:

pip install floodlight

Why

Why do we need another package that introduces its own data structures and ways of dealing with certain problems? And what's the purpose of trying to integrate all different data sources and fit them into a single framework? Especially since there already exist packages that aim to solve certain parts of that pipeline?

Our answer is - although we love those packages out there - that we did not find a solution that did fit our needs. Available packages are either tightly connected to a certain data format/provider, adapt to the subtleties of a particular sport, or solve one particular problem. This still left us with the essential problem of adapting to different interfaces.

We felt that as long as there is no underlying, high-level framework, each and every use case again and again needs its own implementation. At last, we found ourselves refactoring the same code - and there are certain data processing or plotting routines that are required in almost every project - over and over again just to fit the particular data structures we're dealing with at that time.
