Personally I don't know; but I'd like to :) in the meantime; I found that in recent times I've not hit the max memory limit - I'd suggest trying the following options in the meantime: object1 <http://nlp2rdf.org/ontology/nextToken> ?object2 OPTION (TRANSITIVE , T_DISTINCT, t_in(?object1), t_out(?object2), t_max(6), T_DIRECTION 1 , T_NO_CYCLES) . feel free to use either / or T_DISTINCT / t_max and swap out the values to something that runs quickly yet gives you the results you want.
