Continuous Integration (CI) and Free, Libre and Open Source Software (FLOSS) are both associated with agile software development. Contradictingly, FLOSS projects have difficulties to use CI and software forges still lack support for CI. Two factors hamper widespread use of CI in FLOSS development: Cost of the computational resources and security risks of public CI services. Through security analysis of public CI services, this paper identifies possible attack vectors. To eliminate one class of attack vectors, the paper describes a concept that encapsulates a part of the CI system via virtualization. The concept is implemented as a proof of concept.

This paper presents research that investigated the role of conflict in the editorial process of the online encyclopedia, Wikipedia. The study used a grounded approach to analyzing 147 conversations about quality from the archived history of the Wikipedia article Australia. The study found that conflict in Wikipedia is a generative friction, regulated by references to policy as part of a coordinated effort within the community to improve the quality of articles. Finally, the paper addresses the implications of the study in light of larger questions about the quality of information online, as well as diversity and coordination in online communities.

Wikipedia is an important institution and part of the new media landscape having evolved from the collaborative efforts of millions of distributed users. This poster will present ongoing research that examines how the issues that have been highlighted by conflict within the community have shaped the evolution of Wikipedia from an open wiki experiment to a global knowledge producer. Bringing together the concepts of interpretive flexibility and generative friction with existing theories on the evolution of institutions, the research aims to present possible futures for Wikipedia as part of not only the larger Wikimedia movement, but of an open and accessible web.

As the community depends more heavily on Wikipedia as a source of reliable information, the ability to quickly detect and remove detrimental information becomes increasingly important. The longer incorrect or malicious information lingers in a source perceived as reputable, the more likely that information will be accepted as correct and the greater the loss to source reputation. We present The Illiterate Editor (IllEdit), a content-agnostic, metadata-driven classication approach to Wikipedia revert detection. Our primary contribution is in building a metadata-based feature set for detecting edit quality, which is then fed into a Support Vector Machine for edit classication. By analyzing edit histories, the IllEdit system builds a prole of user behavior, estimates expertise and spheres of knowledge, and determines whether or not a given edit is likely to be eventually reverted. The success of the system in revert detection (0.844 F-measure) as well as its disjoint feature set as compared to existing, content-analyzing vandalism detection systems, shows promise in the synergistic usage of IllEdit for increasing the reliability of community information.

As one of the popular social media that many people turn to in recent years, collaborative encyclopedia Wikipedia provides information in a more “Neutral Point of View” way than others. Towards this core principle, plenty of efforts have been put into collaborative contribution and editing. The trajectories of how such collaboration appears by revisions are valuable for group dynamics and social media research, which suggest that we should extract the underlying derivation relationships among revisions from chronologically-sorted revision history in a precise way. In this paper, we propose a revision graph extraction method based on supergram decomposition in the document collection of near-duplicates. We show that this method can effectively perform the task than existing methods.

We ask what kinds of sources Wikipedians value most and compare Wikipedia’s stated policy on sources to what we observe in practice. We find that, contrary to Wikipedia policy, primary data sources developed by alternative publishers are both popular and persistent, and that Wikipedians make almost equal use of information produced by associations such as nonprofits and from scholarly publishers. Our findings suggest that Wikipedians must balance Wikipedia’s internal policy on sources against its goal of representing “the sum of human knowledge.”

In this paper we address the problem of developing actionable quality models for Wikipedia, models whose features directly suggest strategies for improving the quality of a given article. We first survey the literature in order to understand the notion of article quality in the context of Wikipedia and existing approaches to automatically assessing article quality. We then develop classification models with varying combinations of more or less actionable features, and and that a model that only contains clearly actionable features delivers good results. We discuss the implications of these results in terms of how they can help improve the quality of articles across Wikipedia.

Despite the amount of 9/11-related content and enthusiasm with which current news events were promoted on the Wikipedia homepage, the role of this content in the project raised complex questions about the identity and boundaries of the project itself. The outcomes of these debates influenced policies about Wikipedia’s approaches to covering current news events and the types of content it would permit to be included. The scale of editors’ response to the 9/11 attacks motivated the development of policies that served to explicitly demarcate the boundaries of Wikipedia’s encyclopedic identity as distinct from a news source or a memorial site. These initiatives reveal tensions as the community negotiated the role and scope of current news events.

In the first half of 2011, one of Wikipedia’s most prolific counter-vandalism bots (or automated software agents) went down for four distinct periods, each period of downtime lasting from days to weeks. In this paper, we use these periods of breakdown as naturalistic experiments to study Wikipedia’s heterogeneous quality control network. Our analysis showed that the overall time to revert an edit was almost doubled when this software agent was down. Yet while a significantly fewer proportion of edits made during the bot’s downtime were reverted, we found that those edits were eventually reverted. This suggests that other agents in Wikipedia took over this quality control work, but performed it at a much slower rate.
