There are a few reasons why mentions of research outputs are not always automatically picked up by Altmetric:
The mention did not include a working link to a page with the research output identifier (e.g. the DOI), so it couldn’t be picked up automatically by our software - this sometimes happens with blog posts, or if a link has been added to a news story after it is first published (we only scan them once).
The text mining system (which we use for news and policy only), was not able to match a research output to the story by identifying the journal title and author name.
We weren’t tracking the source when the mention was published. To track a news source we need to index it in our database. To track blog posts they need to have a working RSS feed. All attention must be available and open. Altmetric cannot track materials that are behind a login or a paywall.
The mention included a link to another news story or press page about the research, rather than to the research itself. This is often the case with Tweets and Facebook posts. These are known as second order citations, which we don’t track.
The mention was in a comment, rather than in the original post or article.
Our policy is to manually add mentions that should have been picked up automatically, if we are notified about them.
If we come across a blog or news story that would never have been picked up automatically when it was first published, for one of the reasons listed above, we add it to the “misc” tab on the article details page. Posts on the misc tab do not influence the Altmetric Attention Score, (as we don’t want to bias the data), but it means that people can still see all the coverage for that research output that we know about.
If you have noticed some missed mentions for your research that you would like to notify us about, please complete this form. We check the surveys regularly, so you should see the mentions appearing on your details page within a day or two.
If you'd like to suggest a source (e.g news outlet, blog, Facebook page etc) please send your request to firstname.lastname@example.org and we can look into adding it to our database.
