yes but you should extend it and make more discussion

You can publish. but, u need to acknowledge that the paper was presented at such and such conference. Better if you can incorporate the suggestions you received.

Yes, You can.

If you presented a paper in a conference whose proceedings are not indexed, you can send this paper to a journal for publishing.

However, if the proceedings of the conference are indexed, then you cannot publish this paper in a journal.

30% to 50% new content as compared to conference paper is needed in journal article.

You cannot publish exact the same version of the paper. In order to publish in a journal, you need to have some new content. The amount of new content depends on publishers policy which is about 30-40%. This new contribution is not only text, but also new research, research result, etc.

In my opinion, if the conference does not have proocedings you should not have signed any copyright form, so... your paper is not published and you can publish everywhere

@Vasile, good comment! Your suggestions are valuable, while @Luca explains very copyright aspect of. Therefore, conjuction of these two answers is full answer to @Sudhakar!

My paper is selected for poster presentation in IEEE conference. I am disappointed that paper was not selected for publication. I have worked a lot on this paper and want to publish it ?

Echoing everyone that has answered before, I believe that it's OK to publish but need to be mindful of copyright and self-plagiarism. You may want to read this short blog post of mine, on this very topic: http://achilleaskostoulas.com/2014/01/11/can-i-publish-a-conference-paper-in-a-journal/

@Achilleas Kostoulas

Good comments/observations. Thanks!

Dr. Anchelleas, perfect answer. Thanks a lot.

Do you think it would be smart if I go through conferences which does not request full-length papers? So that I submit the first page with Abstract only, and afterwards, I can submit the whole paper to a journal. This means, that the article submitted to the journal won't contain more than 10% of the one submitted to the conference..

Dear @Sudhakar, dear friends, please do visit some related threads with many answers.

No....

My answer is my perception towards this problem.....

A conference presentation carries several suggestions and advice which are sometimes principle related or the literature describing the problem. Incorporating these ideas and re-writing is a good idea which as good as going for publishing the modified one in Journal. Incorporating the ideas suggested by the chair is actually like giving respect to the chair.

I really like to consider presenting a paper at a conference as a good way of getting ideas from a direct audience before publishing it for peer review.

Usually what you present in a conference is an abstract. So as far as I know you can publish a full paper later enriched with extra information.

Dear Dulan Jayasekara , full papers are presented at the most of the scientific conferences, behind posters. It is good to hear the voice of your peers, and then to prepare the paper for a Journal, if it is not considered unethical. So, the author MUST inform the Journal that paper was presented at the Conference. Some Journals do not accept such practice of publishing.

Of course, but in my experience you need to change it and get similarity index lower the 20-30% Depend on Publisher. Of course also as Ljubomir said inform the Journal that paper was presented at the Conference.

Yes but you can not just repeat the presentation. You must significantly modify the conference paper to turn it into a publication. Some time ago the normal pathway to a publication was to first present a conference paper and then consolidate the conference paper into a publication.

Not copy and past, but rephrase, and cite the conference paper.

Yes, of couse!

You can publish, as long as you add some original content to the manuscript. The percentange of the original content may vary from Journal to Journal. For example, Frontiers require 30% original content. Good luck !

Of course you can but similarity can not be over 30% of the conference paper I think so.

Good question.

Thanks to all researchers for valuable suggestions. A lot of researchers have i believe would benefit from this discussion

Dear Dr. Sudhakar,

Of course you can publish your paper after presenting it in a conference.

There are predatory conferences as there are predatory publishers and journals. Here is an example about malpractice from South Korea.

Media probes raise questions over quality of conferences

Researchers and academics at some of South Korea’s top universities have used their university’s research funds to attend academically questionable international conferences and submit their conference reports as examples of internationally excellent journal publications to the national research database, undercover journalists and an international media investigation have found.

Among the South Korean academics attending science conferences of questionable academic quality – or ‘predatory’ as some have been dubbed by academics – were individuals from its top universities, including its prestigious Seoul National University, Korea University and Yonsei University, collectively known as SKY, as well as other top national universities...

You can rephrase, update parts, change its title whereas the similarity less than 20-30%.

Yes you can. You can use the underlying philosophy but ensure that the journal manuscript adds scientific knowledge (at least 50%) besides that of the conference paper. It is best to mention in the journal manuscript that it is an extension of the work done and then cite your conference paper.

A very good questions, thank you all for the response. i have also learn from the piece

actually, am at the crossroads and this just gave me a smooth ride in my thoughts

Yes you can do that

yes but you should extend it and make more discussion

yes you can do that but need make paraphrasing to avoid self-plagiarism

In my experience, I have already noted a lot of papers that are presented in a conference and after that they have been published identically in a journal, even of notoriety.

Even in my own experience, I have already published a paper in the WCTR 2016, held in Shanghai, China, during 10-15 July 2016, which has been part of both the conference proceedings and the Transport Research Procedia Journal the next year, in June 2017. All was already foreseen by Elsevier.

I hope this help you, dear #Sudhakar Singh, though I note your question is dated since 5 years from now, but it may be useful for all other interested persons from now on.

If your conference doesnt have proceedings, or just the abstract was published, then for sure you should publish full article in a journal.

should be no problem, especially when there are no proceedings, but even then many publishers accept papers, provided that they are important contributions...

What the first is concerned don't worry at all, for the second check with the publisher.....

1. To be sincere with you, a paper presented in a conference and you no that the paper will be published in a conference proceeding then it can not be published again.

2. There is what is called an extended paper: that is paper published from conference presentation, then the paper will be publish in a journal after the authors must have effects almost 50% changes in the paper, starting from the, title; abstract; introduction; methodology; result and conclusion. When this is excellently done the authors can published it in a journal. this process will help to handle the self-plagiarism
