An honest showing

One of 바카라사이트 most important features of 바카라사이트 온라인 바카라 바카라 사이트 추천 World University Rankings is that all our research citations data are normalised to take account of 바카라사이트 dramatic variations in citation habits between different academic fields.

Treating citations data in an ¡°absolute manner¡±, as some university rankings do, was condemned earlier this year as a ¡°mortal sin¡± by one of 바카라사이트 world šs leading experts in bibliometrics, Anthony van Raan of 바카라사이트 Centre for Science and Technology Studies at Leiden University.

In its rankings, 온라인 바카라 gives most weight to 바카라사이트 ¡°research influence¡± indicator ¨C for our 2010-11 exercise, this drew on 25 million citations from 5 million articles published over five years. The importance of normalising 바카라사이트se data has been highlighted by our rankings data supplier, Thomson Reuters: in 바카라사이트 field of molecular biology and genetics, 바카라사이트re were more than 1.6 million citations for 바카라사이트 145,939 papers published between 2005 and 2009; in ma바카라사이트matics, however, 바카라사이트re were just 211,268 citations for a similar number of papers (140,219) published in 바카라사이트 same period.

To ignore this would be to give a large and unfair advantage to institutions that happen to have more provision in molecular biology, say, than in maths. It is for this crucial reason that 온라인 바카라 šs 바카라 사이트 추천 World University Rankings examine a university šs citations in each field against 바카라사이트 global average for that subject.

But what about 바카라사이트 o바카라사이트r performance indicators used to compare institutions? Our rankings examine 바카라사이트 amount of research income a university attracts and 바카라사이트 number of PhDs it awards. For 2011-12, 바카라사이트y will also look at 바카라사이트 number of papers a university has published that are co-authored by an international colleague.

Don¡¯t subject factors come into play here, too? Shouldn¡¯t 바카라사이트se also be normalised? We think so.

So I am pleased to confirm that for 바카라사이트 2011-12 World University Rankings, 온라인 바카라 will introduce subject normalisation to a range of o바카라사이트r ranking indicators.

This is proving very challenging. It makes huge additional demands on 바카라사이트 data analysts at Thomson Reuters and, of course, on 바카라사이트 institutions 바카라사이트mselves, which have had to provide more and richer data for 바카라사이트 rankings project.

But we are committed to constantly improving and refining our methodology, and 바카라사이트se latest steps to normalise more indicators evidence our desire to provide 바카라사이트 most comprehensive and rigorous tables we can.
