Impact factors of GIScience journals continue to increase in 2016

 

 

I am not a particular fan of the journal impact factor (IF): it is obsolete, it is susceptible to manipulation, and it does not guarantee quality. Furthermore, the distribution of citations within the same journal is usually highly skewed, which makes itinappropriate to talk about arithmetic means (on which IF is based). Even some editors of journals with a high IF denounce itopenly.

Having said that, it’s hard to deny its importance in academia. For instance, in some countries it conditions promotions and the allocation of government funding.

For starters: the impact factor is a measure of citability of recently published papers in a journal. It is supposed to quantify the influence, reputation, and prestige of a journal; and everything is gauged and consolidated in a single number. The IF of a journal is calculated yearly as the number of references made to all papers published in the journal in the two preceding years, divided by their number (resulting in the yearly average of citedness of recent papers). For instance, the impact factor in 2015 of a journal is calculated as the ratio of cites in 2015 to papers published in 2013 and 2014, and the number of papers published in 2013 and 2014. For example, the journalHousing Theory & Society had published 42 papers in 2013 and 2014. In 2015 there were 43 cites to these 42 papers, as indexed by Thomson Reuters, resulting in an impact factor of 1.024. This also means that papers published before 2013 do not count. The same goes for papers published in 2015 (so a citation from a 2015 paper to a 2015 paper doesn’t count, nor ever will, oddly enough). Finally, not all journals have an IF – only those that are considered influential and of high quality by Thomson Reuters.

The IFs are announced yearly by Thomson Reuters in theJournal Citation Reports. The impact factors for 2015 have just been announced in the 2016 Journal Citation Reports. You can check them here if your institution has a subscription.

As I did last year, I checked the new IFs for the 19 journals that I consider relevant to people in GIScience. The list is composed from my scientometric paper published in IJGIS earlier this year (with the exception of JOSIS – Journal of Spatial Information Science, because it is not yet indexed by Thomson Reuters). For an extended list of journals please see the page compiled by my group.

The results are presented in the table below, also with the IFs in 2013 and 2014:

table

Generally the IFs continue to rise, as it was the case last year. On average, the IFs grew 16.5%.

The impact of 5 out of 18 journals has dropped: PFG‘s IF shrank by 24% (highest in relative terms), and IJDE’s by 0.5 (highest in absolute terms).

Cartography and Geographic Information Science is a clear winner, as its IF continues to grow substantially – from 0.5 to 2.2 in just two years.

While some journals experienced a considerable boost, in the previous edition their IF plummeted. See the case ofGeoInformatica: 1.288 in 2013, down to 0.745 in 2014, and up by 42% to 1.061 in 2015. A substantial increase, but still lower than what it had two years ago.

One news is that the ISPRS International Journal of Geo-Information (IJGI), the Open Access journal published by MDPI got its IF (0.651) for the first time.

For some journals it paid off to deliberately delay paginating papers to boost the impact factor. There are some quintessential cases of holding papers without pagination for a long time, likeTransactions in GIS:

2016-06-14 at 09.38

For IJDE that was not so lucrative: despite that the journal holds papers for long, its IF dropped. I wonder how much further it would drop if they didn’t employ such methods.

In total, the sum of all IFs continued to increase:

This might indicate that GIScience papers are recently attaining an increased reach outside the field. The results also show that IFs can be quite dynamic: IFs really go up and down, and in just one year their difference can be substantial, as for a third of journals (6/18) the IF changed by more than 30%.

Despite the general aversion to the IF, and its flaws, it’s certainly good news that GIScience papers continue to get more attention.
