Our mission is to track the conversations around research outputs online wherever they're happening. To that end we're constantly looking for new sources of data.


Specifically what we're looking for are sources that regularly link to scholarly content, though in some cases like news outlets and policy documents we're also able to perform text mining to try to match research mentioned (but not linked to) with published scholarly articles.


Attention sources


Altmetric currently tracks the following attention sources for mentions of research outputs. Where possible we surface the original text of each mention, and in some cases are also able to provide demographic data on the author of the mention. It's crucial to us that all of our data is fully auditable, and that you can see not only how many people are talking about the research, but who they are and what they're saying. 


Policy documents


We track a wide range of public policy documents for mentions. We define policy documents as any policy, guidance, or guidelines document from a governmental or non-governmental organisation. 


Mainstream media


You can check out the news sources page on the Altmetric website for the latest list of news sources that we track. This list currently extends to over 5000 English and non-English global news outlets. 




We maintain a manually curated list of over 15,000 academic and non-academic blogs. These are tracked automatically via RSS feeds. More information about blogs can be found here.
