The hardest part of sports analytics is getting data! Not for nothing there are companies, which earn their money just with sports data. But if you are not able or do not want to pay such amounts of money, you got just one possibility: scraping the data from the Web. In an older post, I described a R web scraper. As this one was no longer working, I needed a new one. What brings us to this post. This time I will describe, how to create a web scrapper for static HTML sites with Python and how you are able to implement such a web scrapper as a User Defined Function (UDF) in Exasol.
As Exasol changed the way, how to build a customer Python3 docker container, this instructions no longer work. I have to update the single steps.
There is one big reason, why I have chosen Exasol as a database for my football analytics and predictions: Exasol is capable of executing Python and R code inside the database. Your are able to put your statistical calculations and predictive models to your data. The feature User Defined Functions (UDFs) provides the possibility to implement every logic which you normally code in Python or R. This is a really efficient way to extent plain SQL with some predictive functionality like the execution of TensorFlow models.
In this blog post I will explain, how you extend the Exasol community edition with all needed Python3 packages to execute Tensorflow models.
The 2018/19 season in the Premier League started entirely normal. After a record-breaking season Manchester City was of course favoured to win again the title with Liverpool just having an option as the runner-up. But things changed in December and, according to both coaches, we can expect the match between “the best team in the world” and “the best team in the world”.
So which match could be more usefull to take a look at the MACD analysis for both teams and get a better feeling how this type of analysis can be used to identify the performance trend of a team.
