چکیده
Usage of field-normalized citation scores is a bibliometric standard. Different methods for field-normalization are in use, but also the choice field-classification system determines resulting scores. Using Web Science data, we calculated using same formula different systems to answer question if or similar. Six were used: three based on relations, one semantic similarity (i.e., topical relatedness measure), journal sets, and intellectual classifications. Systems sets classifications agree at least moderate level. Two out relations Larger differences observed third data set The main policy implication that normalized impact rankings them should not be compared without deeper knowledge classification used derive these values rankings.
