There is some other problem than just high support. Another rule in the same task ( ?b <interacts_with> ?a ) => ( ?a <interacts_with> ?b ) | HeadCoverage: 0.9917529917281246, HeadSize: 11702183, Support: 11605675
has almost identical support (11605675), but for this rule the confidence is computed in several seconds.
The problematic rules are ( ?b <provided_by> ?c ) ^ ( ?a <provided_by> ?c ) => ( ?a <interacts_with> ?b ) | HeadCoverage: 0.9993713138822047, HeadSize: 11702183, Support: 11694826
and ( ?a <category> ?c ) ^ ( ?b <category> ?c ) => ( ?a <interacts_with> ?b ) | HeadCoverage: 0.9918052042084797, HeadSize: 11702183, Support: 11606286

This bug is possibly a duplicate of #74
from rdfrules.
It is the combinatorial explosion. One solution is to have an anytime approach with sampling and approximated results. Now, I added a better debugging of stucked rules and a possibility to interrupt mining or confidence computing tasks. Fortunately, during mining, the hardest rules are mined at the end of the refining rules queue.
