The Rankprop web server is no longer available.


Rankprop is a ranking algorithm that exploits the global network structure of similarity relationships among proteins in a database by performing a diffusion operation on a protein similarity network with weighted edges The method employed on this server is based on the following publications:

A snapshot of the web server source is available here
Source for the experiments is available here.
The current Torch5 implementation of the Rankprop algorithm can be found here.
The website requires the source for the experiments to be installed along with supporting software such as Torch5 (The Machine Learning toolbox).


The Rankprop server was created by Iain Melvin, Jason Weston, Rui Kuang, Christina Leslie and William Stafford Noble.

This web server was supported by National Institute of Health grant GM74257.

This work was also funded in part by award EIA-0312706 from the National Science Foundation.

Jason Weston and Iain Melvin also thank NEC Laboratories America, Princeton, where they work, for their support of this project.
