Who Wrote This? Creator Metadata Quality on Academia.Edu

Author : Zachary Schoenberger

Academic social networking services (SNSs) such as ResearchGate.com or Academia.Edu have recently experienced a surge in popularity (Ortega, 2016). Existing research into academic SNSs have focused on population parameters and social networking usage patterns. Currently, no research has been conducted on the quality of bibliographic metadata on academic SNSs.

Bibliographic metadata functions to support user tasks, including finding, identifying, selecting, and obtaining information resources. “Creator” metadata, which describes resource authorship, helps users find and identify digital works in a repository.

Additionally, academic researchers rely on author attribution for their professional promotion and prestige, and they are accustomed to scholarly environments which implement standards that support accurate author attribution.

This study therefore examines “creator” metadata for University of Alberta publications posted on Academia.Edu, and compares these with publisher created records of the same titles. Metadata quality is assessed through the measurement of completeness, consistency, and accuracy.

The study reveals that Academia.Edu “creator” metadata is significantly incomplete compared to publisher metadata, and the frequency of incomplete records increases in proportion to the size of the author cohort. This incompleteness is evidence of poor metadata quality on Academia.Edu.

Academia.Edu “creator” metadata is, however, much more consistent than publisher metadata. Finally, accuracy is found to be an inadequate determiner of metadata quality, as the presence of user generated metadata calls into question the conceptual stability of “authenticity” and “authority,” upon which a measure of accuracy depends.

This study of metadata quality therefore reveals the complexity and contradiction that underlies this topic. In terms of completeness, Academia.Edu metadata is poor in quality. In terms of consistency, Academia.Edu metadata excels in quality.

Finally, the study recommends further investigation into the definition of authority in relation to user-contributed metadata.

Bibliographic Metadata Harvesting to Support the Management of…

Bibliographic Metadata Harvesting to Support the Management of an Institutional Repository :

« This thesis approaches the problem of automatic harvesting of bibliographic metadata records from several indexing services, in the context of the population of institutional repositories. Since the manual insertion of records is a tedious and error-prone task, the automation of the process intends to facilitate the management of a repository. However, the automated harvesting of records has to deal with the problem of identifying authors and with the need to consolidate duplicate records retrieved from different services. In an approach to the automation of the aforementioned task, we introduce a system that proposes to harvest bibliographic metadata records from different information sources publicly available, identify and consolidate the retrieved records that are considered duplicates and make available the results of such consolidation to external parties that are interested in the information, such as an institutional repository. The proposed system was tested with real bibliographic metadata corresponding to scientific publications of a subset of faculty members at Instituto Superior T´ecnico. The results of the evaluation show that, despite the required time to identify and consolidate, the merged records contain a valid aggregation of all available information in the system and can be efficiently accessed by external entities through a machine-to-machine interface. »

Open Bibliography for Science, Technology, and Medicine

The concept of Open Bibliography in science, technology and medicine (STM) is introduced as a combination of Open Source tools, Open specifications and Open bibliographic data. An Openly searchable and navigable network of bibliographic information and associated knowledge representations, a Bibliographic Knowledge Network, across all branches of Science, Technology and Medicine, has been designed and initiated.

For this large scale endeavour, the engagement and cooperation of the multiple stakeholders in STM publishing – authors, librarians, publishers and administrators – is sought. BibJSON, a simple structured text data format (informed by BibTex, Dublin Core, PRISM and JSON) suitable for both serialisation and storage of large quantities of bibliographic data is presented.

BibJSON, and companion bibliographic software systems BibServer and OpenBiblio promote the quantity and quality of Openly available bibliographic data, and encourage the development of improved algorithms and services for processing the wealth of information and knowledge embedded in bibliographic data across all fields of scholarship.

Major providers of bibliographic information have joined in promoting the concept of Open Bibliography and in working together to create prototype nodes for the Bibliographic Knowledge Network.

These contributions include large-scale content from PubMed and ArXiv, data available from Open Access publishers, and bibliographic collections generated by the members of the project. The concept of a distributed bibliography (BibSoup) is explored. »

Loading Brief MARC Records for Open-Access Books in an Academic Library Online Catalog

Mbooks are open-access, digitized books freely available on the Internet. This article describes the Auraria Library’s experience of loading brief MARC records for Mbooks into its online public access catalog and looks at some of the issues that arose from the record-loading project.

Despite the low quality of the records, librarians in Auraria Library thought that loading them into the catalog was advantageous because of the rich content in the collection, and because many of the records could be improved using the global update functionality in the catalog.

Making the records available through the catalog, as opposed to merely linking to the entire collection from the Library’s Web page, was considered to be valuable because of the aggregation a catalog provides, and because the Mbooks collection helped fill gaps in the Library’s physical collections.

As more open-access, digitized books become available, libraries will need to plan and manage how best to provide access to them.
