PaperRater.org reads the daily submission to any category of arXiv and searches for published papers on The SAO/NASA Astrophysics Data System (ADS).

## Browsing papers

To get your daily brew of papers, go to your preferences and set your arXiv categories of choice. Then, a simple click on the “ArXiv -> Last 24h” link in the header gives you the entire list.

With the All-in-one search field on the top of each page, you can form arbitrarily complex queries. Hovering over the “?” next to it shows you a list of options. In short, you can search for a paper title; first author, possibly with a range of years for the publication; arXiv ids and time slices; and tags.

Since it is very convenient to search for tags, any shown tag is clickable, and gives you all papers, for which this tag is set. As an exception, the “Most common tags” next to your search results act as filter to narrow down the paper list.

To see which papers are really hot right now, just click on the PaperRater logo. The list shows papers with recent contributions by PaperRater user, who have a similar research interest to yours.

## Your contributions

There are three main ways how you can help PaperRater.org to help all of its users, namely by

• rating,
• tagging or
• commenting

papers. You can rate every paper only once, but you can change the rating later at any time. Your rating is anonymous. The distribution of ratings will be shown once a sufficient number of ratings is reached.

You can add as many tags to each paper as you like, but three is often a good number. These tags can be updated at any time.

The most important aspect of these contributions: No other user can find out, which papers you rated or even what your rating was, nor what tags you chose.

In contrast, comments are meant to be public. If you, for whatever reason, decide that you want to stay anonymous when expressing your thoughts, you can chose to do so for any comment independently. We still think that your opinion would have a stronger impact when connected to you as a person, but we understand if you have doubts. Your thoughts are very welcome either way.

Comments support LaTeX, thanks to the astonishing MathJax, since this is the language we often can best express out thought in. This means, you can let other users know that formula N in paper X should actually read like

$J_\alpha(x) = \sum\limits_{m=0}^\infty \frac{(-1)^m}{m! \, \Gamma(m + \alpha + 1)}{\left({\frac{x}{2}}\right)}^{2 m + \alpha}$

as opposed to

$J_\alpha(x) = \sum\limits_{m=0}^\infty \frac{(-1)^m}{m! \, \Gamma(m + \alpha + 1)}{\left({\frac{x}{2}}\right)}^{2 m}.$

The syntax is very simple, use $...$ for inline math and $$...$$ for blocks.

## Rules of Engagement

We understand PaperRater.org as an open platform, which gives you the opportunity to express your opinion on the quality of publications. However, we do enforce certain standards of discussion.

Since every user can rate a paper only once, it may seem tempting to create several user accounts in order to have a stronger influence on the rating results. We have taken precautions to identify and prohibit such a behaviour and will suspend questionable accounts.

Comments are public contributions. They can and should be critical, but remain rational. Insults or the like can be flagged as inappropriate by other users. We reserve the right to block such comments.

By contributing, users grant PaperRater.org the non-exclusive and irrevocable right to distribute this contribution. This is the minimum requirement to make these contributions public. The users maintain the right to publish their contributions in other forms.

PaperRater.org cannot be held responsible for the opinions expressed in comments or the content of websites, which can be reached by hyperlinks placed in comments.
