H-index in chemoinformatics

Peter blogged about the h-index, which is a measure for ones scientific impact. He used Google Scholar, but I do not feel that that database is clean enough. I believe a better source would be the ISI Web-of-Science.

Therefore, I composed a list of h-indices of my own, ordered by value. The choice of authors is biased to the Blue Obelisk and the CDK, has some personal touches (Buydens are Wehrens are my PhD supervisors) and some names that put the rest into perspective:


queryh-index#pubs
BENDER A41222
WILLETT P37302
GASTEIGER J33212
RZEPA HS25236
BUYDENS LMC18108
GLEN RC1878
WEHRENS R1147
MURRAY-RUST P*941
STEINBECK C929
FECHNER U612
GUHA R424
WILLIGHAGEN E*49
WEGNER JK39
LUTTMANN E24


Of course, there are many comments on this. Like any measurement, take into account the error. Sources of error include, but are not limited to, ambiguity in the query. The most notable example of this, I think, is Andreas Bender; I don't think he has been that successful :) Also, Rajarshi Guha's h-index was reported 6, but the list included two articles from the 70-ies and 80-ies, which I do not think are actually really his.

Feel free to suggest other names, query corrections, tips, and I will add or work on those too.

  1. Egon,
    Are you sure that these are single authors. I know Andreas published a lot of papers during his PhD but I thought it was ca 16, not over 200. I suspect there is another A Bender somewhere.

    Also there is clearly a cutoff in time - I have published a lot more than 41 papers. And there are 4-5 other Murray-Rusts so the initial matters.

    But thanks for the post - it proves my point which is that you can make the numbers vary wildly according to how

  2. Peter, you are correct about Andreas. I did make a remark on his high score, but was not very verbose on the problem his h-index.

    Nothing much I can do about articles no indexed in WoS. BTW, what would the correct query for you?

    It would be interesting to see whether there at least is correlation between h-indices calculated from Google Scholar, PubMed and WoS.
