Journal ranking - ISI, etc.

Following ISI's introduction of a 5-year Journal Impact Factor measure, I took another look at the position of Information Research and found that its 5-year JIF is 1.309, which ranks it 16th out of 56 in ISI's rather curious list. However, when we look at the 'general purpose' LIS journals, leaving out the niche journals, like Scientometrics, and those journals that are not really in the LIS field, like MIS Quarterly, and ARIST, which is an annual serial rather than a journal, we find IR in the fifth position, headed by Information Management, JASIST, IP&M, and Journal of Documentation.

IR's climb up the ranking lists is recognized by the Australian Research Council's draft journal ranking for its Excellence in Research initiative (which will form the basis, if I understand things aright, of its equivalent of the UK Research Assessment Exercise) - IR appears as an A* journal, along with those mentioned above.

Thanks to John Lamp of Deakin University for making the list available.

SCImago Journal and Country Rank

News of a new journal ranking site from the SCImago research group at the University of Granada. Described as follows:
The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.). These indicators could be used to assess and analyze scientific domains.

This platform takes its name from the SCImago Journal Rank (SJR) indicatorpdf, developed by SCImago from the widely known algorithm Google PageRank™. This indicator shows the visibility of the journals contained in the Scopus® database from 1996.

A natural question for me, then, is: How does Information Research show up in this new ranking? So, I took the journals that are similar to Information Research, in that they are not 'niche' journals, but publish widely across information science, information management, librarianship, etc., from ISI's Journal Citation Reports and then gathered the data from SCImago. To reduce the effort of creating a table (not as easy in Blogger as it is in Free-Conversant) I have taken the top 10 journals from the list:

The use of the h-index is well known in the bibliometrics fraternity and is normally used to measure the productivity and impact of an individual scholar. One of its problems, particularly significant in ranking journals, is that the longer the period in which the scholar (journal) has been active, the more likely it is that the scholar (journal) will receive a high h-index, so it's usefulness here may be limited. However, it is interesting to see that Information Research has an h-index of 12, while older journals have lower measures.

The SJR measure is explained as,
...an indicator that expresses the number of connections that a journal receives through the citation of its documents divided between the total of documents published in the year selected by the publication, weighted according to the amount of incoming and outgoing connections of the sources.

The 'cites/doc' measure is based the number of citations received in the previous four years and the total number of documents published in 2006.

JIF is the ISI Journal Impact Factor.
