UFC/MMA Scrape README File
Objective
The purpose of this project is to scrape historical MMA data on fights and fighters, clean the data, and create new feature variables to make it as useful as possible. Project was written in R, using package rvest for scraping.
Files
0-wiki_ufcbouts.Rscrapes the results of every UFC fight from Wikipedia (or updates an existing fight DB).1-wiki_ufcfighters.Rscrapes the details of every fighter that has ever fought in the UFC and has a Wikipedia page. Fighter details include: age, height, reach, wins/losses, nationality, team/camp association, etc.wiki_ufcbouts_functions.Rhouses all custom functions used in ufcbouts scrape file.wiki_ufcfighters_functions.Rhouses all custom functions used in ufcfighters scrape file.
Instructions
Save folder mma_scrape to your current working directory. There are two scrape files
(0-wiki_ufcbouts.R and 1-wiki_ufcfighters.R), file 0 must be run prior to running
file 1. The two function files provide functions used for scraping and are
sourced at the top of each of the scrape files. The output of each scrape file is
a dataframe saved as an .RData file to the folder mma_scrape. If the ufcbouts scrape
file has been run in the past and the output .RData file exists in the directory mma_scrape,
then running ufcbouts again will ONLY scrape new fight records that have been added to
Wikipedia since the last time the script was run, appends the new records to the
boutsdf dataframe and saves it back to the same .RData file.
Notes
The majority of the code is performing text clean up, text extraction, tidying variables and creating new feature variables. I'm planning on add more to this in the near future (scraping historical judging data for all MMA fights, merging of datasets).
