Journal Impact Factors Miscellaneous
Journal Impact Factors
I am maintaining a graph of the ups' and downs of ISI impact factors on journals that are relevant for Machine Learning and for Robotics. If you think a major journal is missing, then please drop me a line.
It is somewhat interesting to compare the different journals in the absolute number of citations listed by SCOPUS (which captures more sources than ISI). These paint a very different picture about TRo? and IJRR over the last five years: IJRR has always had way more citations while having way fewer articles. Clearly, ISI has biased towards TRo? and against IJRR (alternatively, one could claim that SCOPUS predicted the future ISI impact factor of IJRR for 2010). See yourself:
Here are the same plots for machine learning.
Similarly, SCOPUS indicates a different picture.

I have started monitoring the Robotics and Machine Learning journals. Based on this list of ISI impact factors for 2006 and based on ISIKNOWLEDGE.COM for 2007, I have created a list of the most current impact factors. As impact factors for 2008 are measured on 2008 publications, the impact factors for 2008 will not be available until mid-2009. My best tools right now are ISI-KNOWLEDGE and SCImago Rank. NL mean "Not Listed".

| Note that the IEEE Transactions on Robotics was originally much lower (only 0.813 in 2007). The editor-in-chief Alessandro De Luca achieved a recount which lifted the journal from #5 in Robotics to #1. Subsequently, Thomson Reuters, the official publisher of JCR and ISI Web of Knowledge/Science, corrected their results based on their own data. Upon request, I can provide the printouts of the ISI rankings, but the results can also be obtained from Thomson Reuters upon subscription. I cannot make these printouts publicly available due to legal reasons. Also note that the SCImago needs to be interpreted with a grain of salt as it is not based on the updated JCR results. Here are the updated factors. In 2008, book chapters and conference proceedings were included into the citations. Hence, do not take 2008 too seriously. | |||||

| Apologies for the upper cases but cut & paste is soo much easier... While any quantitative measure on scientific quality is at best dubious, the recent ranking on robotics journal rankings seems to confirm the listing above. | |||||
