During the national day, the Chinese tennis Open is in full swing in Beijing, ten years of development, now the Chinese network has become China's most influential tennis tournament, in the media workshop in the network, two rows of intranet computer is particularly conspicuous. In these 10 computers, you can access all the lottery, game and a variety of technical statistics, including the player information, which includes the pros and cons of each player in the net, the success rate of the service, Internet success rate, Ace Ball number and so on almost all the data you can think of, these large data, built a digital network.

Medium Network Media Center

Able to provide detailed competition data to reporters

The Media Center, which provides the most detailed data for every media worker, is a good source of material for journalists reporting events, and for players, the material is also an important basis for their preparation.

If your opponent is a rookie who has never played before, data analysis can be a big help to you, and you can tell from the data what kind of player this is. And in the face of a famous Maria Sharapova, if you can analyze her data carefully, the same can be done early training before the fight. As of the One-fourth final, Sharapova in the net to win 78, after Makalova and Kuznetsova, and her forehand winning probability is 10%, the backhand winning probability is only 4%, which shows that the forehand is significantly stronger than the left and right, so in the face of Sharapova to try to play the ball to its backhand, Yang Jankovic's backhand winning score is 7%, which proves that her pros and cons are more balanced compared to Sharapova. In addition, in front of the net scoring rate, Sharapova 19 shots 16 times scored, 84% success rate proved that she in this network before the net performance is quite good. In addition to the front of the net, Sharapova in the Q.

According to China Network Organizing committee staff revealed that the computer in the last year, the network has been installed by the sponsor of IBM to provide technical support. In addition to the event, the sponsor provided the player data is very fine, if the player can use this as a reference, for preparation. Now, in the top tennis players, Djokovic, Nadal, etc. will be based on statistics to find opponents and their own weaknesses, to do targeted training, the use of data to improve technology is their off-season an important lesson.

In collaboration with IBM from last year, IBM has designed the Matchtracker (race tracking system) with real-time and large data analysis function for the network, which can provide the fans with data presentation and scoring functions. Matchtracker based on IBM SlamTracker Data analysis technology enables fans to leverage historical and real-time data to gain insight into the situation and strategy behind the score. In this respect, the famous four grand slam competitions have long been at the front, especially the oldest Wimbledon, and now many fans have been unable to accept the Wimbledon open without slamtracker.

Since 2005

IBM starts collecting grand slam data

Zhou Yi, Vice president and chief Marketing officer at IBM Greater China, said: "The big collection of the game statistics is actually one of the things we've been doing since 2005, as of 2013 we've tracked all 8,128 games in 8 years, and we've collected and analyzed 41 million data points." 2012, IBM also launched a new feature ——— keys to the match (winning key points), which is perhaps the biggest highlight of SlamTracker, this feature is used to determine the performance of the players in the game pattern and style, will give you a very deep understanding of the players. "Keys to the match" what the specific meaning, according to the introduction, its function is to find each game against the two players won the three key indicators, for fans, such statistics can help them find the focus, so also become professional tennis fans standard.

In the case of the Wimbledon men's singles final last year, Djokovic versus Murray, Djokovic's three winning points were the 4th beat to the 9th beat of the winning rate, Ace Ball number, return ball success rate, and Murray's three key points are the return to the ball scoring rate, two success rate and service success rate. "Keys to the Match" not only found these three key points, but also found the quantization of the pass line. Last year at the French singles final, the "Keys to the Match" told Serena Williams, to defeat Sharapova, the other side of the return ball scoring rate to fight for more than 36%, and in turn, Sharapova to defeat the small Williams, the other side of the return ball scoring rate to win more than 28%. If a player completes better than B in these three indicators, the likelihood of a winning is much higher than B, and eventually Little Willie does better, and as expected, she wins the championship with two 6:4 over Sharapova.

An analysis like this is that these three indicators are not common indicators, such as the 4th shot to the 9th beat of the winning, this obscure data is not seen on the television screen. However, these obscure indicators measure the situation and determine the key to success or failure. Through data analysis, IBM's 3 winning points are both the focus of fans ' attention and the barometer of player status.
