Making Visualization Work for Institutional Repositories: Information Visualization as a means to browse electronic theses and dissertations

Authors : Leila Belle Sterman, Susan Borda

INTRODUCTION

An attractive repository with clear, well-structured and accessible content can be a powerful recruitment and publicity tool for administrators, fundraisers, and others trying to bolster support for repositories.

Digitizing ETDs is a lengthy and often arduous process. Once that process is completed, it is often a victory that suffices. As a result, collections frequently receive no further treatment. We demonstrate the benefits of visualizing repository content.

DESCRIPTION OF THE PROJECT

The goal of the project was to create an interactive visualization to make our newly digitized theses and dissertations more discoverable.

By leveraging the institutional organization of College, Department and Year of Graduation, we visualized data to help users understand ETD content as a whole and find specific items more easily.

BUILDING THE VISUALIZATION

The process begins with data cleanup involving extracting and normalizing repository metadata, then the data is processed and the Data-Driven Documents (D3) JavaScript library is used to generate the actual visualization.

Benefits of Visualizations to Users: The visualization allows for the sort of happenstance discovery of materials that are celebrated about shelf browsing and a way to compare the productivity of each college and department at our university. It also illustrates our institution’s changes in emphasis over time.

NEXT STEPS

Visualizations have vast potential for creating engaging user interfaces for digital library content. We would like to explore how people are using the visualization as we move forward with this process to visualize multiple collections.

Mapping the Intellectual Structure of the Open Access Field Through Co-citation Analysis :

« Open access has been one of the major research trends and hottest topics in electronic publishing. This paper aims to assess the evolution of open access as a research field using bibliometric and scientific visualization techniques. It maps the intellectual structure of open access based on 281 articles that appeared in professional literature on the topic between 2000 and 2010. Using bibliometric and co-citation analyses, co-citation patterns of papers are visualized through a number of co-citation maps. CiteSpace was used to analyze and visualize co-citation maps. Maps show major areas of research, prominent articles, major knowledge producers and journals in the field of open access. The letter written by Steven Lawrence (“Free online availability substantially increases a paper’s impact”, 2001) appears to be the most prominent source as it was cited the most. The journal article by Kristin Antelman (“Do open Access articles have a greater research impact”, 2004) and the report by Alma Swan and Sheridan Brown (“Open access self-archiving: An author study”, 2005) are the second most highly cited papers in the network. JASIS / JASIST is the most frequently cited journal by the authors writing on open access. The most recent research topics appear to be institutional repositories, open access publishing/open access journals and scientific communication. Stevan Harnad is most frequently co-cited author, followed by Alma Swan, Steven Lawrence and Peter Suber. The preliminary findings show that open access is an emerging research field. Findings of this study can be used to identify landmark papers along with their impact in terms of providing different perspectives and engendering new research areas. »
