In the genitive cluster, for example, there were 18,936 such pattern instances, of which 325 encoded part-whole relations, while 18,611 did not.
for the genitive cluster we used a training corpus of 27,961 positive examples (325 pairs of concepts in a part-whole relation extracted from corpus "A" and 27,636 extracted from WordNet as selected pairs) and 18,611 negative examples (the non-part-whole relations extracted from corpus "A").
