Citation metrics author database for many scientific fields

Antonio Papangelo's picture

Citation metrics are widely used and misused.  Ioannidis and co-authors have created a publicly available database of 100,000 top scientists that provides standardized information on citations, h-index, coauthorship-adjusted hm-index, citations to papers in different authorship positions, and a composite indicator.

I have extracted here some data of interest for the Mechanical Engineering field (I'm a mechanical engineer by training), for scientist from all over the world and for Italian scientist. The tables report data obtained for 22 years (from 1996 to 2017) and for a single year (2017). 

You find also the link to the original paper. This is an incredible source of data, publicly available, which could be used for a number of studies and comparisons!!! Feel free to go to the original source and provide new analysis based on this huge data collection!

Update 29/08: more data attached.

Jim Rice second, and many other friends in the ranking. Congratulations to John!

I am honored to be n.4 in Italy after Carpimteri, Pugno, Maier. All my esteemed friends and colleagues. Most of them I also have papers with. I think the ranking is really good.

the paper which is making big noise is

 

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0221212

 

Citation gaming induced by bibliometric evaluation: A country-level comparative analysis

Alberto Baccini ,Giuseppe De Nicolao,Eugenio Petrovich

 

which suggests, because of biblimetric incentives, italians made an exageration of selfcitations in the late years.

 

Plos-ONE is I beleive on an inferior rank journal than Plos-Biology, one of those you pay to appear into.........

 

However, the Plos-ONE paper appeared covered in the main italian newspaper, Corriere della SERA, because it is more easy to call it a scandal, than a pure ranking of nice scientists

 

https://www.corriere.it/cronache/19_settembre_11/i-professori-si-citano-...

 

in the Plos-Biology Ioannides papers, we would exclude self-citations, how many more italians would be in the 100k instead of 2000?

I have no time to check.

 I have been one of the most active promoters of Ioannides ranking in Italy, and the most appropriate criticism I have found comes from mathematicians.

 

I went to look for names of established mathematicians, starting with the last 8 Fields Medals, and the result is this:

Maryam Mirzakhani       absent

Martin Hairer                   absent

Manjul Bhargava         absent

Artur Avila                     absent

Caucher Birkar          absent

Alessio Figalli                 absent

Peter Scholze                   absent

Akshai Venkatesh                absent

 

Maybe the mathematicians were not considered? No, here are some, three Medals and two famous Italians, with their respective positions in the standings:

 

Luigi Ambrosio  11604   CNR (?)

Michael Atiyah  26058

Steve Smale             26324

Cedric Villani          40253

Gianni Dal Maso 98906

 

What is wrong with the mathematicians in the ranking?

 

 

Here is the answer. Mathematics has the lowest citation density of any scientific field because there is very few mathematicians as opposed to say geneticists or physicists or or any other field experts. This means that very few mathematicians will make it to the top 100000 of the aggregate list but as is said in the paper they advise people not to use the aggregate but look separately for each field, otherwise it makes no sense to compare geneticists against mathematicians.

 

The few mathematicians that are making it to the career 100000 list are mostly older ones where their work had sufficient time to accrue citations. By definition Fields medals are awarded to people very early in their careers, in their thirties, sometimes even before tenure, so it is expected that the recent Field medalists will not make it. What I am curious though is whether you think that those who did make it are not really very good mathematicians (even if older on average).

 

 

Moreover, Hairer, Avila and Figalli are included in the top 100000 in the S2 file...

Not everyone is so convinced. John Ioannidis, a specialist in metascience studies at Stanford University in California, says the change in national self-citations doesn’t seem particularly extreme, and might be due to chance. He added that if the increase is real, it could have been driven by a minority of researchers.
