Olympics subgraph within DBpedia datasets

Hi there,

I am doing some analysis with DBpedia databus sets and wonder if there is a way to extract a subset (say, anything with label ‘Olympics’) from “categories_lang=en_labels.ttl.bz2” that contains only info related to Olympics and other sports events connected to it. I’m using rdflib from Python but if there is a better way to handle these ttl files, I’d be more than happy to learn.
