The first big european event in the Rio2016 qualification period occured on the weekend and it is a good time to explore the data we now have freely available from the IJF.

This year The International Judo Federation (IJF) released the Judobase.org website. This site has been in development for sometime and now is available, for free, to anyone. The site is similar to the venerable judoinside.com site, with a couple of important differentiators.

1) It is created from the official IJF data systems.

What this means is that this is the “official” source of data, and coming direct from the IJF IT systems it should be more accurate.

It does however mean that it only covers the IJF events, so judoinside remains the go to site for a complete picture of athletes career. The JudoBase site will not tell you if/when a player won their national championships, etc.

2) Scores.

Judobase being intergrated into the IJF data systems is able to capture and include scoring data. So you can see when a score happens in each fight (only available in more recent events). So it has more detail.

3) Video.

Once again being integrated has it’s advantages, the video from the official cameras is being encoded and uploaded with only a small delay to Judobase.org. You can click on a contest and watch the video (whilst looking at the scores) and really get the data you need.

4. WRL Integration

The judobase system already includes the athletes world ranking list (WRL) data. This is currently coming from the manual systems but will I imagine become the canonical source for ranking data.

So what can we discover?

The statistical side of Judobase.org is not very mature, it is really only an indication of what is possible. I would hope that the readers of this blog would quickly find ideas and share them so that the Judobase system can automatically generate relevant data for enthusiasts, fans and researchers.

 

So the latest event at the time of writing is the Budapest Grand Prix; and this is available at http://judobase.org/#/competition/profile/1166

A new Olympic qualification cycle begins, Rio2016

Leave a comment

On May 31st 2014, the qualification period for the Rio2016 Judo tournament began. This is the start for the nations and athletes of the final build-up to the pinnacle event in Judo, the Olympic Games. judobase_bannerAnd this site will be following along closely and exploring the numbers. The qualification system for Rio2016 is similar to that of London2012, in simple terms the 22 men and top 14 women in the world get entry into the games. Then a quota system is used to select players from the ranking list from a wide variety of nations. As with the last Olympic cycle, the IJF Senior World Ranking List is the most important element in an athletes qualification chances.

 

As with the last cycle we expect to see players approach qualification in different ways. Teams struggled with qualification last cycle and no doubt will again. Although we hope that they have a better understanding of the system than last time around. Only the British have an excuse for not understanding it as last time round they did not need to qualify players; this time the Brazilians have that advantage.

 

The WRL also affects the seeding at each event, and for the games itself. As such, it is really important for athletes to monitor the WRL and manage their entries to try and get as high on the list as they need to be. The next 6 months will be interesting to see how the better teams have chosen to distribute the athletes. We have seen many of the big names getting rehab since London and many have obviously been taking time out and getting set for the trials and traumas that follow.

 

I personally am very interested in how strategic entry into events affects the WRL. So, stay tuned as this site will try and be very active for the next two years leading up to Rio2016. A new resource is available to us now also, the newly launched IJF http://judobase.org site contains the absolute best data direct from the IJF on every event (its a IJF only http://judoinside.com ).
