  We present a new concept - Wikiometrics - the derivation of metrics and
indicators from Wikipedia. Wikipedia provides an accurate representation of the
real world due to its size, structure, editing policy and popularity. We
demonstrate an innovative mining methodology, where different elements of
Wikipedia - content, structure, editorial actions and reader reviews - are used
to rank items in a manner which is by no means inferior to rankings produced by
experts or other methods. We test our proposed method by applying it to two
real-world ranking problems: top world universities and academic journals. Our
proposed ranking methods were compared to leading and widely accepted
benchmarks, and were found to be extremely correlative but with the advantage
of the data being publically available.
