SlamTracker

IBM SlamTracker

Australian Open SlamTracker, a real-time stats and analytics visualisation platform, is leveraging IBM's predictive analytics technology to pinpoint three "Keys to the Match" that each player needs to come out ahead. Advanced algorithms analyse more than 39 million data points from five years of Grand Slam tournaments. Served with this historical data, each competitor's performance styles and patterns are then indexed across the pair's head-to-head record to generate the top three "Keys" each competitor needs to win.

KEY STRENGTH:  
The Key Strength indicates how important this key is to the match.

The importance is determined by the distribution of data available for the player, the player's opponent and other analytical factors used to define the key.
