P5B: Metadata / Exploring Metrics and Assessment
User Search Terms and Controlled Subject Vocabularies in an Institutional Repository
University of Kansas, United States of America
Controlled vocabularies are an important mechanism for ensuring consistency in a repository and necessary for maximal collocation for searching by subject. The University of Kansas Libraries' is in the process of implementing FAST as a subject vocabulary for its institutional repository, KU ScholarWorks. Of the metadata fields used for retrieval, subjects are particularly valuable, allowing for a type of collocation less easily achieved through titles or abstracts. However, the quality of subject terms can vary based on policies guiding their selection. If controlled vocabularies present a solution for reducing metadata 'noise', one must also consider the search behavior of the user. How well do user queries align with a controlled vocabulary, and what's the level of effort required to reconcile legacy subject terms with a new vocabulary? Our analyses uses search queries which led users to items in our repository. These queries are reconciled against FAST terms, legacy subject terms, and more broadly across repository records to determine the potential effects on search behavior. The effort required to reconcile legacy metadata will be considered as the repository seeks to reconcile its history of uncontrolled language with a more systematic and extensible vision for the future.
Metadata at a crossroads: shifting ‘from strings to things’ for Hydra North
University of Alberta Libraries, Canada
At the University of Alberta Libraries we are currently developing a Digital Asset Management System (‘Hydra North’, built on Hydra and Fedora 4) to bring all of our digital assets into one platform for discovery, access and preservation. The metadata underlying these repositories has been created according to many standards (DC, MODS, EAD, etc.) and varies in level of fullness and overall quality. We find ourselves at a ‘metadata crossroads’ as we attempt to bring this disparate metadata together. We see a solution in a move to RDF and the application of the principles of linked data. In this presentation we will discuss some of the initial questions we asked ourselves as we tried to fully grasp what the move to RDF and linked data would mean for our existing metadata; outline some of the decisions we made along the way, and why, and what the impact has been; provide concrete examples of the thought processes and workflows involved in moving from existing non-RDF metadata to RDF, based on the principles of linked data; provide an update on progress to date; reflect on lessons learned and outline next steps.
"How much?": Aggregating usage data from Repositories in the UK
1Jisc, United Kingdom; 2Cranfield University, United Kingdom; 3Evidence Base, Birmingham City University, United Kingdom
IRUS-UK is a national standards-based statistics aggregation service for repositories in the UK provided by Jisc. The service processes raw usage data from repositories, consolidating those data into COUNTER-compliant statistics by following the rules of the COUNTER Code of Practice – the same code adhered to by the majority of scholarly publishers. This will, for the first time, enable UK repositories to provide consistent, comparable and trustworthy usage data as well as supporting opportunities for benchmarking at a national level. This talk provides some context to development, benefits and opportunities offered by the service, an institutional repository perspective and future plans.
Incorporating COUNTER compliant download statistics into an EPrints repository
The Open University, United Kingdom
Researchers are taking repository download statistics more seriously than ever before, and are citing them in funding bids as evidence of previous impact. The repository staff are receiving more enquiries relating to download statistics as time goes on, so having the most accurate and reliable statistics available is becoming clear. Having them available in a way that requires the least intervention of repository staff would allow for more efficient dealings with other repository tasks, such as deposit review, etc.
In this paper, I look at the issues faced with incorporating, into the repository, statistics from IRUS-UK (Institutional Repository Usage Statistics, UK based) – a JISC supported, centralized system which collates the download statistics for 75 UK repositories, ensuring better than COUNTER compliance. I also consider the choices to be made with regards to comparisons to locally derived statistics (IRStats2) and how to obtain and present them without overburdening the central system.
Finally I look to what opportunities the near future may hold, with reference to my participation on the IRUS-UK community Advisory Group and the NISO SUSHI-Lite Working Group to establish a light-weight RESTful standard for SUSHI services and how these might be incorporated into the repository.
