Our Hiberlink project has been extended to the end of June 2015. A four-month extension was agreed by the Andrew W. Mellon foundation to enable the team to conduct further analysis on reference rot.
In particular, we will process a dataset of empirical observations gathered over the last year on reference rot as it happens in real time in a data corpus of research papers published in January and February 2014. This dataset will be analysed using methods and tools developed earlier in the project in order to quantify and explore the rate and extent of content drift.
The quantification methods developed by the Hiberlink project, and the results of their application to a large data corpus of 3.5 million articles, are presented the recently published (26 December 2015) Plos One paper:
We will also take advantage of this extension to continue our dissemination efforts. Amongst others, Hiberlink will be the subject of a breakout session at UKSG 2015 in Glasgow on 30 and 31 March 2015.
'Reference rot' refers to either link rot when a web link is broken and no longer work, or content drift when the link points to content that is drastically different to what it was originally.
Hiberlink is a collaborative project between EDINA and the Language Technology Group in Informatics at the University of Edinburgh, and the Los Alamos National Laboratory Research Library. This project is funded by the Andrew W. Mellon foundation.
