Wikis are designed to support collaborative editing, without focusing on individual contribution, such that it is not straightforward to determine who contributed to a specific page. However, as wikis are increasingly adopted in settings such as business, government, and education, where editors are largely driven by career goals, there is a perceived need to modify wikis so that each editor's contributions are clearly presented. In this paper we introduce an approach for assessing the contributions of wiki editors along several authorship categories, as well as a variety of information glyphs for visualizing this information. We report on three types of analysis: (a) assessing the accuracy of the algorithms, (b) estimating the understandability of the visualizations, and (c) exploring wiki editors' perceptions regarding the extent to which such an approach is likely to change their behavior. Our findings demonstrate that our proposed automated techniques can estimate fairly accurately the quantity of editors' contributions across various authorship categories, and that the visualizations we introduced can clearly convey this information to users. Moreover, our user study suggests that such tools are likely to change wiki editors' behavior. We discuss both the potential benefits and risks associated with solutions for estimating and visualizing wiki contributions.

Software development is fundamentally a collaborative task. Developers, sometimes geographically distributed, collectively work on different parts of a project. The challenge of ensuring that their contributions consistently build on one another is a major concern for collaborative development and implies concerns with effective communication, task administration and exchange of documents and information concerning the project. In this demo, we present WikiDev 2.0, a lightweight wiki-based tool suite that enhances collaboration within software development teams. WikiDev 2.0 integrates information from multiple development tools and displays the results through its wikibased front-end. The tool also offers several analysis techniques and visualizations that improve the project-status awareness of the team.
