[total-impact] [total-impact] [total-impact]

Total-Impact is a Web service measuring the diverse impact of several types of research artifacts across the Web. It allows users to create collections of identifiers of research papers, datasets, slides, software projects and to generate reports of their respective impact in social media, blogs, wikis and other online scholarly outlets. The concept was originally hacked at the Beyond Impact Workshop° and the project is currently led by Heather Piwowar and Jason Priem under the new name: ImpactStory. Both the original° and the current source code° is released under the MIT License on GitHub. Total-Impact is one of the top 10+1 applications shortlisted for the Mendeley-PLoS Binary Battle° in November 2011. It tweets from @impactstory.

[notabilia] [notabilia] [notabilia]

Notabilia visualizes the longest Article for Deletion discussions in the English Wikipedia. It's a collaboration with Moritz Stefaner (visualization) and Giovanni Luca Ciampaglia (data analysis) and it was launched on the occasion of the 10th Anniversary of Wikipedia. Article for Deletion (AfD) discussions are represented by a thread starting at the bottom center of the screen. Each time a user recommends to keep, merge, or redirect the article a green segment leaning towards the left is added. Each time a user rec­ommends to delete the article a red segment leaning towards the right is added. As the dis­cussion progresses, the length of the segments as well as the angle slowly decay.

Notabilia is the winner of the interactive visualization gold prize at the Information is Beautiful Awards (2012)° and was listed by Co.Design among the "22 best infographics of 2011"°. It was part of the InForm exhibit° (2011) for the Adobe Museum of Digital Media° and of the FutureEverything Art Exhibition° (Manchester, 2012).

[fgt] [fgt] [fgt]

Group Trackr is a Web service designed to track and analyse demographic and activity metrics for public Flickr groups. It pulls data from the Flickr API° on a daily basis and generates analytic reports in a variety of formats. Graphs displaying recent group activity are updated on a daily basis and can be exported as widgets. Once a group is tracked, a detailed group activity report is generated with several performance indicators. Group growth data can also be syndicated via feeds or downloaded as CSV. The service includes an internal search engine and generates dynamic maps of the ’flickrsphere’ based on individual group metrics°. It allows group admins to register to the service in order to monitor the temporal evolution of their groups via a dedicated dashboard. The project started in 2007 and has been partly developed since 2008 within FP6 project PATRES° as a tool to obtain data for a series of empirical studies on online group dynamics. As of december 2009, it tracks the daily growth of more than 15K groups and counts 4K registered users°. It currently attracts an average of 30K visits per month and serves 30Gb of traffic per month. It has been featured in popular social media outlets such as Lifehacker°, Programmable Web° ("Best new mashup"), Yahoo! Gallery° ("Editor's picks"), Computational Aesthetics°, Flickrbits°, the Search Engine Journal°, and the Flickr App Garden°.
