The symposium on Angiography/Scintigraphy dropped at Mainz within the fall of 1970 not just many eu colleagues with an curiosity in those thoughts, but in addition a few viewers from in a foreign country. those busy, work-filled days are commencing to fade within the reminiscence of these who have been there. however, the clinical effects mentioned on that get together nonetheless offer the tips for what's at present being performed in radiology and nuclear drugs.

If neither i nor j is ranked, ppref ignores the pair. If i is ranked but j is not, ppref considers i to have been ranked above j. The pairs in ppref can be weighted for a measure we call wpref. We use a rank-based weighting scheme: for pages at ranks i and j such that j > i, let 1 . wpref is then the sum of weights wij over pairs i, j the weight wij = log (j+1) 2 such that i is preferred to j and the rank of i is less than the rank of j. The normalizing constant is the sum of all weights wij . 1 Results We compared evaluations between four diﬀerent measures: DCG, normalized DCG (NDCG), ppref, and wpref.
1 Transitivity If assessors are consistently transitive, the full set of judgments is not necessary; this is the idea behind comparative sorting algorithms such as heapsort. The rate of growth in the number of comparisons needed by these algorithms is in O(n lg n), much slower than the O(n2 ) growth rate of all comparisons. To evaluate transitivity, we iterated over all triplets of documents i, j, k in each set of preference judgments. We counted the number of times that, if i was preferred to j and j was preferred to k, the assessor also preferred i to k.
