If a journal has the following characteristics, it may belong to the category of predatory journals

(1) Emphasizing on open access fee 

(2) Not listed in Scopus or Thomson Reuters web of science data base

(3) Promising acceptance in fewer days

(4) Not subjecting the submitted manuscripts to peer review process

(5) Bombarding your email again and again begging for submission

(6) Showing unrealistic impact factors (>2 to 10) for a journal which does not have back volumes for at least last five years 

(7) Having the same name as that of some established journals causing confusion for authors

(8) Do not have proper DOI (Digital Object Identifier). If you put the DOI in the website http://dx.doi.org/, it will not redirect to journal link where article is published

(9) Appointing fake or name shake editorial board

(10) Advertising too much for "Call for papers"

(11) Overseeing or bypassing plagiarism check before acceptance 

(12) Scope of the journal is ambiguous accepting multi disciplinary topics for publication.

A good source of information about potentially predator journals in here - http://beallslist.weebly.com/

Thanks Peter for sharing Bealls list.  But this web page is going to be down. And many  agencies don't accept Bealls list.  All we know is,  who don't maintain the quality is not good one.  How to handle them at national or international level?  

Simply ignore those journals whose Editors are repeatedly tempting you to published papers within a very short period of time in lieu of processing fees.

I agree Subir. But the step you suggested is individual response not a step to handle them at national and international level. 

If all universities across the globe follow ISI and Scopus listed publication alone (excluding open access journals) for awarding degrees, faculty promotion, Performance appraisal, annual reports etc,  the survival of  predatory journals will be questionable.

I strongly agree Dinaharan. But there is no coordination among all Universities, Institutes across the globe. Its seems also impracticable to ordinate them all in this issue.  I am thinking for suggesting some practicable steps to regulate them. I must point out here that some publishers (seemed to be predatory in nature) have already pooled this matter to court against some people who advocated against predatory journals. Also NCBI/USA have taken strong steps against this despite the result is almost negligible. 

It is an uphill task to reach a coordination among international universities. South Africa where I am presently positioned presently has strict guidelines to publish only in ISI listed journals. Every year, DHET (Department of Higher Education and Training) sends updated list of ISI list to all universities. If any researcher or faculty publishes outside this list, it will not be counted for awarding degree and faculty promotion. Awareness on predatory journals is increasing in global context. In INDIA, some universities are marching towards this strategy. For example, Anna University demands its doctoral scholars to publish at least two articles in ISI listed journals (https://cfr.annauniv.edu/research/annexure-1.php?alpha=A)  for the award of PhD degree.   

Last five years, there is a huge campaign going on for open access publication and making the article open access by leading publishers. Some open access journals are sponsored by the University or Research Institute or any organization which runs the journal(s) while other open access journals directly charge from authors. Some open access journals have already made their entry into ISI and Scopus database. I have noticed that some of those open access journals are in the transition mode to become a predatory journal. There is a publication group in INDIA which charges any where between Rs. 2000 to Rs. 10000 for publication. All their journals are indexed in Scopus database. Obviously, they are predatory journals. ISI and Scopus database should come forward to remove those journals from their database. Sadly, it has become a huge business to earn money and those corporate publishers can find any loop holes in the system.  

So far as I know UGC has also recently published a list of journals approved by them for publication.

I am also aware of this list of UGC approved journals. (http://rgniyd.gov.in/sites/default/files/pdfs/academic/prof_advt_oct_2016/rgniyd_journals_approved.pdf).

That list has so many journals which are not in ISI list but in Scopus list. All those journals mentioned only in Scopus database can not be trusted as a non predatory journal. Some of them could be predatory. Please refer the following link

Some time ago there was row that researchers from leading institutes in INDIA published in Predatory Journals.

http://www.thehindu.com/sci-tech/science/Researchers-from-national-institutes-publish-in-predatory-journals/article16806280.ece

I have attached a research article published in Current Science on Predatory Journals

Yes many of the journals are predatory in UGC list. Do you all agree to write an article on it together.  I have a framework on it.  Also wrote substantially.  

Dear Dr.  Biswaranjan Paital,

This is very important topic and many researcher don't know exactly what it meant, 

Completly agree with Isaac Dinaharan except the point number 2. We can't simply predict that all journals indexed in Scopus/Thomson/Web of Science are genuine and good standard journals, but for sure they maintain a strict process of evaluation of the journals to be included. On the other hand, we can't simply label all other journals which are not indexed in in these databases as predatory. There are hundreds of journals, though, they are not in these databases but maintain high quality.

dear Biswaranjan, you may have a look into my recently published paper discussing these aspects in detail.

Article ACADEMIC WRITING AND PUBLISHING IN INDIA: IS QUALITY A TOUCHSTONE?

Beall's list is now down and officially banned. It is simple burocratic science

Any journal on Bealls list is a predator. They basically publish anything for a fee of about $1000. If you are foolish enough to submit a paper to such journals and realise your mistake they will charge you a withdrawl fee of about $500. Their websites look just like respectable journals and use the same type of submission software. Unfortunately Beall’s list has been shut down but the predators continue.

Most respectable universities will not recognise papers published by journals that are not on the ISI Thomson Reuters list. No money or recognition and grant bodies will not credit the publication fee.

Your Research Office should be able to help you about predatory journals.

They are almost fake journal in simple,I think

@Isaac Dinaharan, Great explanation

Dear Dr,

according to my experience with them, they charge mony [may be expensive].

the other problem, they are not present or my be discontunued in SCIMAG hoirnal ranking.

Some other characteristics relate to standard review process. Such journals hardly adopt peer review process. Even if peer review process is followed, it is just for the name sake. Editorial boards of such journals hardly bother for reviewers' concern. Their only concern is to publish whatever comes at their disposal, and some how make money.

These predatory journals are looking for your money and they don´t care about the quality of the paper. If you pay, they basically published whatever, even if it is a fake! Here there is a real history about how somebody sent a paper on which everything was fake...... and the paper was published!

Yes, I do agree with Derek Pyne , therefore, no need for waiting efforts and times.

You can use this site to check the credibility of the journals

Thanks. How authentic the link is?

Many good journals having high impact factor are listed. Many of them are also in Mendley and so in Pubmed.

Nothing us mentioned that under which criteria and who enlisted them.

The fact that there are so many of them is an indication that predatory publication is a booming business, which in effect indicates that people are publishing in them. It is worrying that people use them to amass a lot of publications quickly and get fast promotions.
