Most of these are hosted at arXiv which has a new function, but no ranking.
I’d love to discover interesting papers in the fields I follow, ranked by the community. Much like HN.
Does this exist? How do others keep up to date in their fields?
In ML, I personally like skimming Davis Blalock's Davis Summarizes Papers [2].
arXiv might be a source but hosting only preprints without peer review ends up lowering the average quality of the stuff that shows up in there.
Once you get the search results up you can then refine and sort by: relevancy, recency as well as “citation count” and “most influential papers”.
The later I find especially useful when exploring a new topic.
They have a login account but to be honest I haven’t really explored what that offers. Anyone have an account and finding that useful?
Second, Scopus from Elsevier (a company that plenty of people dislike). You'll need to create an account, and I don't know if non-academic accounts have the same access as academic ones. It has a new "researcher discovery" function I've not used so again can't vouch for its quality. You can set up various alerts apparently, although again I've not used them.
If an author is registered on ORCID you can check their works, but it doesn't appear that anything like RSS feeds are available, unfortunately. Plenty of journals have RSS feeds, but you'll have to hunt them down yourself.
Finally, you might want to check out other platforms and preprint servers, which might have better alerts etc. Try OSF, which hosts a bunch of preprint servers, and also provides hosting for documents and files that accompany published papers. However, it looks like there isn't much comp-sci stuff on there.
I guess you could have a look at figshare.com too for similar reasons.
