Computer Science Rankings

This ranking of top computer science schools is designed to identify institutions and faculty actively engaged in research across a number of areas of computer science. Unlike US News and World Report’s approach, which is exclusively based on surveys, this ranking is entirely metrics-based. It measures the number of publications by faculty that have appeared at the most selective conferences in each area of computer science.

This approach is intended to be difficult to game, since publishing in such conferences is generally difficult: contrast this with other approaches like citation-based metrics, which have been repeatedly shown to be easy to manipulate. That said, incorporating citations in some form is a long-term goal.

See the FAQ for more details.

This repository contains all code and data used to build the computer science rankings website, hosted here:

Adding or modifying affiliations

NOTE: Updates are now processed on a quarterly basis. You may submit pull requests at any time, but they may not be processed until the next quarter (after three months have elapsed).

You can now edit files directly in GitHub to create pull requests. All data is
in the files csrankings-[a-z].csv, with authors listed in
alphabetical order by their first name, organized by the initial letter. Please read CONTRIBUTING.md for full details on
how to contribute.

Trying it out at home

Because of GitHub size limits, to run this site, you will want to download the DBLP
data by running make update-dblp (note that this will consume
upwards of 19GiB of memory). To then rebuild the databases, just run
make. You can test it by running a local web server (e.g., python3 -m http.server)
and then connecting to http://0.0.0.0:8000.

You will also need to install libxml2-utils (or whatever package
includes xmllint on your distro), npm, typescript, closure-compiler, python-lxml, pypy,
and basex via a command line like:

apt-get install libxml2-utils npm python-lxml basex; npm install -g typescript google-closure-compiler

Quick contribution via a shallow clone

A full clone of the CSrankings repository is almost 2GB, and the
csrankings.csv file is too large to edit via the GitHub web site. To
contribute a change without creating a full local clone of the
CSrankings repo, you can do a shallow clone. To do so, follow these
steps:

1. Fork the CSrankings repo. If you have an existing fork, but it is
   not up to date with the main repository, this technique may not
   work. If necessary, delete and re-create your fork to get it up to
   date. (Do not delete your existing fork if it has unmerged changes you
   want to preserve!)
2. Do a shallow clone of your fork: git clone --depth 1 https://github.com/yourusername/CSrankings. This will only download
   the most recent commit, not the full git history.
3. Make your changes on a branch, push them to your clone, and create
   a pull request on GitHub as usual.

If you want to make another contribution and some time has passed,
perform steps 1-3 again, creating a fresh fork and shallow clone.

Acknowledgements and other rankings

This site was developed primarily by and is maintained by Emery
Berger. It incorporates extensive feedback
from too many folks to mention here, including many contributors who
have helped to add and maintain faculty affiliations, home pages, and
so on.

This site was initially based on code and
data collected by Swarat
Chaudhuri (UT-Austin), though
it has evolved considerably since its inception. The
original faculty affiliation dataset was constructed by Papoutsaki et
al.; since
then, it has been extensively cleaned and updated by numerous
contributors. A previous ranking
also used DBLP and Brown’s dataset for ranking theoretical computer
science.
