I have added a third list to this blog, and it is called Misleading Metrics.
The purpose of the new list is to alert researchers to bogus metrics companies that have emerged over about the past year.
Predatory publishers use these metrics to make their journals look legitimate. The metrics companies’ customers are the predatory publishers.
The new page includes the criteria for inclusion. It debuts with these 11 companies:
- Advanced Science Index
- Directory of Journal Quality Factor
- Global Impact Factor
- International Impact Factor Services
- International Society for Research Activity (ISRA) Journal Impact Factor (JIF)
- Journal Impact Factor
- Journal Influence Factor
- Scientific Indexing Services (SIS)
- Universal Impact Factor
If you observe a journal that boasts a score given by one of these metrics companies, then I recommend that you proceed with caution.
Here is an example of how these bogus metrics are used:
This is from the homepage of the International Journal of Research in Advent Technology (whatever that is).
This value was assigned to the journal by International Impact Factor Services. The journal does not have an authentic impact factor assigned by Thomson Reuters. This metric is an impostor.
