  • I do not receive daily digest emails on some weekdays, what happened?

There are three possible reasons:
(1) if the areas you signed up are not very active, then it is normal that you do not receive updates everyday.
(2) arxiv.org may not release new papers in time due to holidays or outages. paperdigest.org will send out digest emails as soon as possible (usually the next day).
(3) It is possible that the emails have been blocked by your email service provider. We notice that users using emails from qq.com experience this problem frequently.


  • How are the highlights in the digest emails generated?

Highlights are machine generated using state of the art artificial intelligence techniques (mainly natural language processing and machine learning).


  • I get digests for more than 200 papers everyday, and I cannot read all of them. How can I receive less?

This is the #1 complaint from our daily digest subscribers.
Root Causes: Some areas are active like ‘cs.AI’, so it is expected to see a lot of new papers everyday when multiple such active areas are selected. The problem gets worse in January-March, since deadlines of many conferences fall in this time range.
Solutions: We recommend three solutions:
(1) We always encourage users to narrow down the selected interests (see How to change my interests?). With fewer interests selected, users get fewer updates.
(2) We have a console for users to filter out papers that they are not interested in. Users can login the console page, and then click on /Digest/Current Week or Last Week. This returns all paper updates in the desired time range. These updates are the same as what we sent out in daily digest emails. Users can type in a keyword in “filter” field to only show papers with the desired keyword.
(3) Users can suspend daily digest service using this link. When daily digest service is suspended, users will not receive daily digest emails, but still receive other updates like conference digest notifications. Users can always re-enable this service using the same link.
