This project parses AdvancedNFLStats.com's play-by-play data set for ingest into a relational database. The primary contribution is parsing the text descriptions of plays to determine the type of play (i.e. run or pass) and how drives ended. The project also includes a simple web application for filtering the plays and generating some play and drive statistics. A running version of this application can be found here: http://football.10flow.com.
If you would like to contribute, please check issues for ideas.
This folder contains CSV files of the raw AdvancedNFLStats.com dataset, as downloaded from Google Docs at the end of the 2012 regular season. Check the original source for updates.
This folder contains Python scripts for parsing the text play descriptions and ingesting them into a relational database. The main script to run is play_parser.py. There are some configuration settings at the top of that file you should check out before running. If you wish to ingest plays int oa database, SQLAlchemy is required, as well as a supported database, such as SQLite, MySQL or PostgreSQL.
This folder contains the responsive web application for filtering the plays and viewing simple statistics. index.html contains all markup and Javascript. Queries are handled by football.php, which issues SQL queries to the database and returns JSON for visualization.
The Python scripts in the play-parser folder are designed to be easily extended. Suppose you wanted to add a column to the database that reports the number of characters in the text description of the play (I know this is useless, but it makes a good example). You just need to make a few changes:
Step 1: Make changes to play_db.py to add the column to the database. On line 28 add:
length = Column(Integer)
On line 49 add:
self.length = p['length']
Step 2: Create a play processor that analyzes the play and generates a value a length. To do this, create a new script called process_length.py and add this code:
class LengthProcessor:
def process(self, play):
play.columns['length'] = len(play.columns['description'])
Step 3: Register this new processor, by adding these lines to play_parser.py at line 44:
import process_length
processors.append(process_length.LengthProcessor)
That's it!
