<li>[if possible] When expensive SPARQL queries or learning problems have been posed, there should be
some way to abandon these if the user has already switched to doing something else. Example: The user
has added 3 positive and 1 negative examples. This is executed as a learning problem, but has no solution (so
DL-Learner would run forever unless we pose some internal time limit). The user adds another negative example a
second later, so instead of letting the previous learning problem run for a long time (and needing much resources),
it should be stopped by DBpedia Navigator.</li>
