The Academic Web Link Database Project

Databases of academic web links 2000-2006 for the world research community

This project was created for research into web links: including web link mining, and the creation of link metrics. It is aimed at providing the raw data and software for researchers to analyse link structures without having to rely upon commercial search engines, and without having to run their own web crawler. You may use all of the resources on this site for non-commercial reasons but please notify us if you have an academic paper or book published that uses the data in any way (so that we know the site is getting good use). This site contains the following.

What can the data and software be used for? To count links between universities or departments in various countries; to produce random lists of web pages or URLs; and to analyse the topological structure of national academic webs. Here is an example of statistical research about semi-supervised learning on graphs from another team using this data.

Some of these programs require large amounts of memory. Please save any work before running them in case they crash your computer. The programs are being offered as a free service and as a result they have not been tested in other environments. They should run on most versions of Windows. Please email if there is any problem. Some of the programs may take a long time to run (days if you have a slow computer and are processing the large database files). We are sorry for the awful interfaces provided on the programs but are happy to advise researchers on which programs will be useful to conduct the type of analysis that they are interested in.

Description of Crawling Methodology

Basic crawling techniques and issues are described in: A Free Database of University Web Links: Data Collection Issues. Additional crawling issues and techniques are discussed in the following article.

About this project

This project is run by the Statistical Cybermetrics Research Group at the University of Wolverhampton. We do not charge for any of the data or tools placed here because we feel that we have an obligation to make our raw data available for free since we collected it for free from the Web sites covered. The crawling is resource intensive and time-consuming so we are unfortunately not able to respond to requests such as "please crawl country X". If any bodies, such as national research agencies, would like to see their countries' universities included, then this would involve a charge. We would expect, but not insist, that the data resulting from such an arrangement would be subsequently made available on this site, also without charge.
