What we index, and what we do not
We list academic events only: conferences, congresses, symposia, colloquia and academic workshops with a call for papers or a scientific programme. We do not list trade shows, expos, product launches or sales events.
Every candidate is scored automatically before it is published. The score looks at whether the event describes itself in scholarly terms, whether the organiser is an institution, society or university, whether the dates make sense, and whether the organiser appears on our blocklist of documented predatory publishers. Entries that score well are marked verified; entries that pass but with less evidence are published below them and checked again later; entries that fail are not published at all.
The day after a conference ends its entry stops appearing among current conferences, automatically, every day. Nothing is deleted: the entry is kept and can still be found under past conferences, because a conference that has happened is still a fact worth recording.
How the indexer works
Our indexer identifies itself on every request as:
conference.international-indexer/1.0 (+https://conference.international/about#indexer)
It follows a few rules without exception:
- It reads
robots.txtbefore anything else on a site, and stays out of whatever that file disallows. - It leaves a gap between requests and never crawls a site quickly enough to burden it.
- It keeps the plain facts of an event, name, dates, place, subject, and the organiser's own link. It does not copy descriptions, images or page text into our index.
- Every entry links back to the organiser's own website.
If you would rather we did not index your site at all, disallow the user agent above in your robots.txt, or just email us and we will exclude the domain.
Where the data comes from
| Source | Licence | What we take |
|---|---|---|
| Wikidata | CC0 1.0 (public domain) | Conference names, dates, places and official websites |
| CCF deadlines | MIT | Dates, places, submission deadlines and official links for peer reviewed computing conferences |
| Community deadline lists for artificial intelligence and for human–computer interaction | Open source, permissive | Dates, places and submission deadlines for peer reviewed conferences |
| Indico instances run by research institutes, among them CERN and the ICTP in Trieste | Each instance's documented public export API | Events the institute itself marked as a conference: name, dates, place and link |
| Research organisations' own conference listings, among them Sciencesconf, Nature Conferences, EMBL, the Paul Scherrer Institute, IN2P3, SESAME and the Institute for Basic Science | Read as published, subject to robots.txt | The event facts each site publishes about itself |
| Organisers' own websites | Read as published, subject to robots.txt | The event facts a site publishes about itself in machine-readable form |
| Organisers themselves | Submitted to us | Whatever they choose to tell us |
We are grateful to the people who maintain those open datasets. We do not copy other conference directories: no listing here has been taken from a rival index, and we would not want one that had.
Keeping entries right after they are listed
A conference index is only worth reading if it is current, so a listing is not finished when it is published. Every entry that carries a website is looked at again against that website, and where the organiser has moved a date, changed a venue or opened a new deadline, the entry follows what they publish. If a conference page cannot be found on several checks in a row the entry is retired rather than left to go stale, and an organiser who has claimed their listing always overrides us: their correction stands and we do not overwrite it.
Every conference has its own page
Each listing has a permanent page of its own, with the full details, a link to the organiser's site and structured data in the format search engines read, so the conference can be found from outside this index as well as inside it. There is a page for every subject and every country too, so the whole index can be walked through without JavaScript. New pages join our sitemap the day the listing goes in. This costs the organiser nothing.
Proving a listing is yours
Listings are claimed, not assigned. Ask for the claim link from the address published as the conference contact, or from an address at the conference's own domain, and it arrives by email. Most conferences, though, are run from an ordinary personal mailbox, and sharing a mail provider with somebody proves nothing about them — so for those we use the method search engines use instead. We hand out a short code, the organiser publishes it on the conference's own website, we read it back, and the claim link then goes wherever they ask. On a platform that thousands of unrelated conferences share, only the code on the event's own page counts, never a file at the platform's root. Whoever was published as the contact is told by email whenever a listing is claimed by anyone else, so a wrongful claim cannot pass unnoticed.
Correcting or removing an entry
If you organise a conference that appears here:
- To correct it, open the conference's own page here, choose Claim this listing, and edit it yourself once it is yours. Any email address will do — see proving a listing is yours. Or just email us the correction and we will make it.
- To remove it, email hello@conference.international from an address at the conference's own domain, or use the removal link in any message we send you. We remove entries on request, normally within two working days, and we do not ask why.
Being listed is free and stays free. Nothing about an entry changes if you never pay us anything.
Reporting a problem entry
If you think a listed conference is predatory, fraudulent or misdescribed, tell us. Three independent reports suspend an entry automatically while we look at it, and we keep a public blocklist of organisers we will not index.
How the site pays for itself
Organisers can pay for a featured listing or a homepage campaign. That is our only income: no advertising network, no sponsored search results dressed up as ordinary ones, no selling of email addresses. Paid placement is always labelled. Our terms set out exactly what a paying organiser gets, and exactly what we do not promise them.
