Dota 2 database from Steam Web API - where to start?

[seppes]

Hello,

i am working on a machine learning course on udacity, and lately i had the idea of training a neural network with data from Dota 2 - pubgames, making suggestions what picks are ideal.

The problem is, i have absolutely no idea how to get this data from steam. I read something about the Steam Web API but i am not sure about whether it is the right tool to get it from.
In the end, i just need the data of the heroes picked, and which team won. Of course there will be alot of data cleaning afterwards, but at first i would like to get database of public games, can anyone help me how to do it? Would be extremely awesome :)

All the best!
