<p>it's a connection between <code>url</code> and <code>category</code>
And also I have test set and I need to get category to every url.</p>

<p>I don't know, what algorithm should I use to solve this task.
I need the best way to get the most accuracy.
And I think it's a problem, that I have multiple categories.</p>

<p>I try first parse html tag <code>title</code>, because I think, that I can's determine category only with <code>url</code>.</p>
