While scientometrics is now an established field, there are challenges
. A closer look at how scientometricians aggregate building blocks int
o artfully made products, and point-represent these (e.g. as the map o
f field X) allows one to overcome the dependence on judgements of scie
ntists for validation, and replace or complement these with intrinsic
validation, based on quality checks of the several steps. Such quality
checks require qualitative analysis of the domains being studied. Qua
litative analysis is also necessary when noninstitutionalized domains
and/or domains which do not emphasize texts are to be studied. A furth
er challenge is to reflect on the effects of scientometrics on the dev
elopment of science; indicators could lead to 'induced' aggregation. T
he availability of scientometric tools and insights might allow scient
ists and science to become more reflexive.
