Knowledge base queries typically produce a list of entities. For reasons similar as in full-text search, it is usually desirable to rank these entities. A basic ingredient in such a ranking are relevance scores for individual triples. Task: given a triple from a "type-like" relation, compute a score that measures the relevance of the statement expressed by the triple compared to other triples from the same relation.
