Browsing digital libraries with Papercube

Benjamin Wiederkehr — Tue, 28 Jul 2009 06:00:21 +0000

PaperCube is the master research project of Peter Bergstrom at the Santa Clara University. The main obejctive was to find ways to browse digital libraries with a focus on academic paper network navigation.

PaperCube lets the user browse the data of CiteSeerX (Scientific Literature Digital Library and Search Engine) using different views. The user can view Papers in a circle visualization focusing on the interlinkage of papers. A Treemap-type visualization shows citation or reference hierarchy and so does the papers per year but the later adds a chronological context. To get detailled information about a specific paper PaperCube provides a detail view complete with Abstract, references and citations.

The application is built as a RIA using HTML, CSS and the Sproutcore JS framework and runs in all the modern web browsers. You can give it a spin on papercube.peterbergstrom.com.

RANDOM WALK

Benjamin Wiederkehr — Thu, 21 May 2009 10:47:55 +0000

Daniel Becker has published his 2009 diploma thesis RANDOM WALK at the University of Applied Sciences in Mainz, Germany.

What does randomness look like? RANDOM WALK asks this question and presents experiments in mathematics and physics, showing the mysterious interaction of chaos and order in randomness.
The project RANDOM WALK simulates randomness in visualizations, which are easy to understand. In this way, it delivers insight into a phenomenon, which has so far remained unexplained.

Daniel investigates randomness in various topics. Ten sheets explain the phenomena of randomness in mathematics and physics – four focus on all-day randomness and the quality of pseudo random number generators. The thesis consist of a plethora of different visualization approaches but always stays focused on a high visual aesthetic.

The project and it’s documentation are created with much love to detail and a distinct look & feel. We highly recommend having a look at the entire documentation at www.random-walk.com.

well-formed.eigenfactor.org

Well-formed.eigenfactor.org is a cooperation between the Eigenfactor project (data analysis) and Moritz Stefaner (visualization). The project presents interactive visualizations based on the Eigenfactor™ Metrics and hierarchical clustering to explore emerging patterns in citation networks.

The project consists at this time of four different views. A relation circle gives an overview of the whole citation network, inspired by Sankey diagrams and stacked bar charts, the changes over time are displayed in Eigenfactor™ Score and clustered over time. A treemap shows the hierarchical clustering of journals. And a map-like visualization with an interactive magnifier (Go have a look, it’s georgous!) presents a clustering based on citations between journals.

The visualizations are built in Adobe Flash using the visualization library Flare.
