Examining Persistence of European Open Repository Infrastructure and its Diffusion in the Scholarly Record

Authors : George Macgregor, Joy Davidson

This article seeks to determine the extent to which the principle of persistence is observed by repositories and the organizations that operate them. In addition, the impact that negative repository persistence levels may be having on the scholarly record is assessed.

This is achieved by interrogating and combining data on European repositories from several repository registries and web-scraped sources, including the Internet Archive’s Wayback Machine, which creates a unique dataset of historic repository locations and their OAI-PMH endpoints.

Then, this data is used as the basis for text mining CORE, a vast corpus of scholarly outputs, to determine the extent to which impersistent European repository content has permeated the scholarly literature. The findings indicate that over one-fifth of European repositories (greater than 20 per cent) could be classified as “dead,” with an even greater proportion (greater than 40 per cent) of the machine interfaces associated with these repositories similarly dead.

Problematically, this analysis indicates that approximately 12,000 unique scholarly works cite, refer to, or actively use this repository content, amounting to approximately 19,000 unique repository locations, all of which are now dead and unretrievable from their stated resource locations. Partly owing to limitations in available repository registry data and the existence of “zombie” repositories, there are reasons to conclude that the total number of scholarly works referring to dead repository content is far higher.

In addition, evidence of dead repository content entering the current scholarly record is found, which is described as “dead on arrival” referencing.

The implications of these observations are considered, explanations are proffered, and possible policy interventions to address repository persistence are proposed. The dataset also enables several observations on the nature of impersistent repositories to be made, including their profile and their decay rate.

Enhancing Content Discovery of Open Repositories: An Analytics-Based Evaluation of Repository

Author : George Macgregor

Ensuring open repositories fulfil the discovery needs of both human and machine users is of growing importance and essential to validate the continued relevance of open repositories to users, and as nodes within open scholarly communication infrastructure.

Following positive preliminary results reported elsewhere, this submission analyses the longer-term impact of a series of discovery optimization approaches deployed on an open repository.

These approaches were designed to enhance content discovery and user engagement, thereby improving content usage. Using Strathprints, the University of Strathclyde repository as a case study, this article will briefly review the techniques and technical changes implemented and evaluate the impact of these changes by studying analytics relating to web impact, COUNTER usage and web traffic over a 4-year period.

The principal contribution of the article is to report on the insights this longitudinal dataset provides about repository visibility and discoverability, and to deliver robust conclusions which can inform similar strategies at other institutions. Analysis of the unique longitudinal dataset provides persuasive evidence that specific enhancements to the technical configuration of a repository can generate substantial improvements in its content discovery potential and ergo its content usage, especially over several years.

In this case study, COUNTER usage grew by 62%. Increases in Google ‘impressions’ (266%) and ‘clicks’ (104%) were a notable finding too, with high levels of statistical significance found in the correlation between clicks and usage ( t=14.30,df=11,p<0.0005 ).

Web traffic to Strathprints from Google and Google Scholar (GS) was found to increase significantly with growth on some metrics exceeding 1300%. Although some of these results warrant further research, the article nevertheless demonstrates the link between repository optimization and the need for open repositories to assume a proactive development path, especially one that prioritises web impact and discovery.

Improving the discoverability and web impact of open repositories: techniques and evaluation

Author : George Macgregor

In this contribution we experiment with a suite of repository adjustments and improvements performed on Strathprints, the University of Strathclyde, Glasgow, institutional repository powered by EPrints 3.3.13.

These adjustments were designed to support improved repository web visibility and user engagement, thereby improving usage. Although the experiments were performed on EPrints it is thought that most of the adopted improvements are equally applicable to any other repository platform.

Following preliminary results reported elsewhere, and using Strathprints as a case study, this paper outlines the approaches implemented, reports on comparative search traffic data and usage metrics, and delivers conclusions on the efficacy of the techniques implemented.

The evaluation provides persuasive evidence that specific enhancements to technical aspects of a repository can result in significant improvements to repository visibility, resulting in a greater web impact and consequent increases in content usage.

COUNTER usage grew by 33% and traffic to Strathprints from Google and Google Scholar was found to increase by 63% and 99% respectively. Other insights from the evaluation are also explored.

The results are likely to positively inform the work of repository practitioners and open scientists.
