I recently received an invitation to a conference and I'm trying to determine how reputable it is. Is there a good way to go about this?

    You cannot decide whether a conference is reputable based on where it is indexed. Some indexes try to avoid indexing anything with too bad a reputation, but the evidence you would get from this is very minor at best. (Also, the arxiv is not an index.) – Anonymous Mathematician Apr 17 '13 at 15:08

    After the edits, it's not clear what the desired information is. It starts out by asking a general question about determining conference quality, and then focuses on indexing, which is only very tenuously related. – Anonymous Mathematician Apr 23 '13 at 13:07
  • @AnonymousMathematician - I agree. I tried to keep from editing the original question too much, but I think he is asking two separate questions here. – eykanal Apr 23 '13 at 20:26
  • If it advertise with benefits you are not aware of, it's most likely scam (or off-topic; or the organizers are totally clueless). – Piotr Migdal Apr 23 '13 at 21:51
  • If they are offering you free attendance, and you just have to pay for the accommodation, then beware as it might be a "scamference". The conference does not exist. And neither does the accommodation. – Simon B Sep 28 '15 at 13:53

I'm assuming you are really asking how to check whether a conference is reputable (meaning not a scam), not how to check whether a conference is actually good.

Short answer: If you don't recognize the conference or its organizers, stay away.

You should already know a relatively short list of established, reputable conferences in your research area. If you don't, ask your advisor to give you such a list. (If your advisor doesn't know, you need a new advisor.)

If this conference isn't on that list, it might still be reputable, but either very new or slightly outside your research area. In that case, take a serious look at the organizing committee. If the members of the organizing committee are well-known active researchers, the conference is probably fine. Otherwise, it's probably a scam.

You mention that you were invited to submit to the conference. At least in computer science, such invitations are almost unheard of; conferences are normally advertised by impersonal calls for papers. Did the invitation come from someone you already know, at least professionally? Does the invitation mention specific technical details of your work (more than just a paper title)? If you answered "No" to both these questions, the conference is almost certainly a scam.

    I am not sure whether "If you don't recognize the conference or its organizers, stay away." is a good advice. Especially when one is not "years in a field" there is a big chance that there are people one does not know, or conferences about which one have never heard (especially as (at least in my field) it is very common to have a new conference, especially when smaller one). So I wouldn't consider it as a guideline. Sure, when after googling organizers don't do serious work in one's field, it is scam (or off-topic). – Piotr Migdal Apr 23 '13 at 21:48

    Perhaps I should say "if you and your advisor..." Your advisor has been years in the field; it's part of their job to be well-connected, precisely to help you make judgments like this. I'm also assuming that Google is part of your researcher-recognition algorithm. – JeffE Apr 23 '13 at 23:31

    Given that at least predatory publishers lie about their editors, I would not be surprised if the people behind scam conferences lie about the organising committee or similar. – Wrzlprmft Dec 27 '14 at 15:57

    @Wrzlprmft I suspect that's is more a concern in principle than in practice. I have yet to see a scam conference whose organizing committee contained more than a tiny fraction of well-known active researchers. Being a member of a conference committee is an important promotion milestone, which conference scammers are all too happy to provide. – JeffE Dec 27 '14 at 22:55

What I usually do is look at the list of speakers in the current and past years. If the conference is in my field, I usually can tell if the speakers are well-known and what the level of the conference will be. If the conference is not in my field, I google some of the speakers and check out their websites to get an impression.

Another thing which is often helpful to do, is to simply ask someone with knowledge of the field which conferences are good.


In addition to the other answers, it's worth taking a close look at conferences that tick several of these boxes (although some may turn out to be OK on further inspection). These can be warning signs of conferences that are basically scams, or that will be a waste of your time/money/energy.

Items 2-5 are indicators of insufficient peer review, and are problematic only for conferences that claim to publish peer-reviewed proceedings.

Items 6-9 are warning signs that the aim of the conference organizers is profits, not academics.

  1. Organizers, program committee members, or keynote speakers are not established researchers in the field (as per some of the other answers on this page).
  2. It has an extremely short review period (e.g. submissions due November 1, author notification November 10).
  3. You receive reviews that are very short and/or don't say anything insightful about the paper.
  4. The technical program committee is small, but the conference accepts hundreds of papers.
  5. If the conference proceedings are published or indexed by a well-known publisher, look at past editions of the proceedings and check if multiple papers have been retracted or withdrawn for plagiarism and/or for being computer generated.
  6. The scope of the conference is extremely broad, such that people who work in one of the areas of interest are not likely to be interested in presentations from the other areas (this can be a tactic to get a lot of submissions, at the expense of conference quality).
  7. The conference organizer also organizes many other conferences, on a very diverse range of unrelated topics.
  8. The organizer holds many conferences on unrelated topics at the same time and place.
  9. The organizer is also associated with one or more predatory journals, or selected papers from the conference are published in a predatory journal.

Maybe I will add to JeffE’s answer. I agree with him that, in your field, you probably have established your own list of reputable conferences after a few years. However, it does happen that you get invited or submit a paper to a conference that's outside your natural “comfort zone”. One reason is because of a joint work with other authors from that area, another may be that you are shifting the focus of your research, or you published a paper that has potential applications in another field.

Anyway, if that happens, you want to check out the organizers and speakers (keynote speakers if it's a large conference). One or two serious people doesn't mean anything though, especially if the conference is held in an attractive touristic area (Caribbean islands?). Some people accept conferences that they know are not good, if they see a nice opportunity for a holiday in them. However, if half the organizers or speakers are well known, or have well established research groups, then you're probably good to go.


Looking at the program committee, organizers, other presenters (e.g. keynote speakers) and what work they've done is one helpful approach. Asking your advisor is often quite useful.

Also consider if you've read papers from that venue in the past and found them helpful enough and high-quality enough to be citing / using as a basis for your work.

Finally, there's the Computing Research & Education conference ranking portal here which might be another signal to consider.
