Improving revision in wiki-based writing: Coordination pays off Wichmann A.
Rummel N.
Computers and Education English 2013 Wiki-based writing possesses a great deal of educational potential, yet students face difficulties while writing a shared document. Revising a shared document, in particular, seems to be a demanding activity for students. This study investigated whether collaboration scripts can help to improve students' revision activities and overall text quality. We compared scripted (script+) with unscripted (script-) collaboration in a wiki-based writing setting that was adapted for educational purposes. Students from two university courses participated in a one-week collaborative writing activity. Results showed that students in the scripted condition outperformed students in the unscripted condition with respect to revision behavior and text coherence. Furthermore, we found that students' revision behavior correlated positively with text coherence. Results from analyzing students' discussions during the writing activity revealed more frequent coordination with respect to task division and increased communication frequency for students in the scripted condition. Results also indicate that collaboration scripts can foster coordination. Our findings suggest that collaboration scripts are promising means of structuring collaboration during wiki-based writing. © 2012 Elsevier Ltd. All rights reserved. 0 0

English 2013 Online annotations provide an effective way for distributed individuals to better understand and categorize online content, both from the perspective of distilling information presented into more easily interpretable forms and by supporting content analysis to tag individual statements with their intended meaning. This poster presents Indicoder, an application to support in-place content analysis, allowing users to both annotate online corpora and providing a means of tracking those annotations over time so that living documents such as Wikipedia articles and online sources can be analyzed in their authentic contexts.

Frontiers in Behavioral Neuroscience English 2013 Serotonin (5-HT) is implicated in the development of stress-related mood disorders in humans. Physical activity reduces the risk of developing stress-related mood disorders, such as depression and anxiety. In rats, 6 weeks of wheel running protects against stress-induced behaviors thought to resemble symptoms of human anxiety and depression. The mechanisms by which exercise confers protection against stress-induced behaviors, however, remain unknown. One way by which exercise could generate stress resistance is by producing plastic changes in gene expression in the dorsal raphe nucleus (DRN). The DRN has a high concentration of 5-HT neurons and is implicated in stress-related mood disorders. The goal of the current experiment was to identify changes in the expression of genes that could be novel targets of exercise-induced stress resistance in the DRN. Adult, male F344 rats were allowed voluntary access to running wheels for 6 weeks; exposed to inescapable stress or no stress; and sacrificed immediately and 2 hours after stressor termination. Laser capture microdissection selectively sampled the DRN. mRNA expression was measured using the whole genome Affymetrix microarray. Comprehensive data analyses of gene expression included differential gene expression, log fold change (LFC) contrast analyses with False Discovery Rate correction, KEGG and Wiki Web Gestalt pathway enrichment analyses, and Weighted Gene Correlational Network Analysis (WGCNA). Our results suggest that physically active rats exposed to stress modulate expression of twice the number of genes, and display a more rapid and strongly coordinated response, than sedentary rats. Bioinformatics analyses revealed several potential targets of stress resistance including genes that are related to immune processes, tryptophan metabolism, and circadian/diurnal rhythms. 0 0

Conference on Human Factors in Computing Systems - Proceedings English 2011 Dandelion is a wiki-based tool that supports coordinated, collaborative authoring. In this paper, we present an extended version of Dandelion, which provides an email interface for users to accomplish their tasks by email in a coordinated, collaborative authoring process. Specifically, Dandelion employs a semi-structured, template-based approach that allows users to use templates to specify their requests in email. These emailed requests can be interpreted by Dandelion and are then used to automatically drive the collaboration flow. As part of its actions, Dandelion automatically creates a wiki page and dynamically updates it to record co-authoring tasks and collate co-authored content. As a result, users can use their familiar tool (email) to accomplish their tasks in a co-authoring process, while leveraging a wiki for additional benefits (e.g., obtaining collaboration awareness and formatting the text). Our preliminary study with two groups of users shows the usefulness of both Dandelion email and wiki features and their impact on collaboration effectiveness. Copyright 2011 ACM. 0 0
Beyond Wikipedia: Coordination and Conflict in Online Production Groups Aniket Kittur
Robert E. Kraut
Computer-Supported Cooperative Work English 2010 Online production groups have the potential to transform the way that knowledge is produced and disseminated. One of the most widely used forms of online production is the wiki, which has been used in domains ranging from science to education to enterprise. We examined the development of and interactions between coordination and conflict in a sample of 6811 wiki production groups. We investigated the influence of four coordination mechanisms: intra-article communication, inter-user communication, concentration of workgroup structure, and policy and procedures. We also examined the growth of conflict, finding the density of users in an information space to be a significant predictor. Finally, we analyzed the effectiveness of the four coordination mechanisms on managing conflict, finding differences in how each scaled to large numbers of contributors. Our results suggest that coordination mechanisms effective for managing conflict are not always the same as those effective for managing task quality, and that designers must take into account the social benefits of coordination mechanisms in addition to their production benefits. 0 4

Determinants of Wikipedia Quality: the Roles of Global and Local Contribution Inequality Oded Nov Ofer Arazy Computer Supported Cooperative Work (CSCW) 2010 The success of Wikipedia and the relative high quality of its articles seem to contradict conventional wisdom. Recent studies have begun shedding light on the processes contributing to Wikipedia’s success, highlighting the role of coordination and contribution inequality. In this study, we expand on these works in two ways. First, we make a distinction between global (Wikipedia-wide) and local (article-specific) inequality and investigate both constructs. Second, we explore both direct and indirect effects of these inequalities, exposing the intricate relationships between global inequality, local inequality, coordination, and article quality. We tested our hypotheses on a sample of a Wikipedia articles using structural equation modeling and found that global inequality exerts significant positive impact on article quality, while the effect of local inequality is indirect and is mediated by coordination. 0 1

Coordination in collective intelligence: The role of team structure and task interdependence Aniket Kittur
Bongshin Lee
Kraut R.E.
Conference on Human Factors in Computing Systems - Proceedings English 2009 The success of Wikipedia has demonstrated the power of peer production in knowledge building. However, unlike many other examples of collective intelligence, tasks in Wikipedia can be deeply interdependent and may incur high coordination costs among editors. Increasing the number of editors increases the resources available to the system, but it also raises the costs of coordination. This suggests that the dependencies of tasks in Wikipedia may determine whether they benefit from increasing the number of editors involved. Specifically, we hypothesize that adding editors may benefit low-coordination tasks but have negative consequences for tasks requiring a high degree of coordination. Furthermore, concentrating the work to reduce coordination dependencies should enable more efficient work by many editors. Analyses of both article ratings and article review comments provide support for both hypotheses. These results suggest ways to better harness the efforts of many editors in social collaborative systems involving high coordination tasks. Copyright 2009 ACM. 0 0
Herding the cats: The influence of groups in coordinating peer production Aniket Kittur
Pendleton B.
Kraut R.E.
WikiSym English 2009 Peer production systems rely on users to self-select appropriate tasks and "scratch their personal itch". However, many such systems require significant maintenance work, which also implies the need for collective action, that is, individuals following goals set by the group and performing good citizenship behaviors. How can this paradox be resolved? Here we examine one potential answer: the influence of social identification with the larger group on contributors' behavior. We examine Wikipedia, a highly successful peer production system, and find a significant and growing influence of group structure, with a prevalent example being the WikiProject. Comparison of editors who join projects with those who do not and comparisons of the joiners' behavior before and after they join a project suggest their identification with the group plays an important role in directing them towards group goals and good citizenship behaviors. Upon joining, Wikipedians are more likely to work on project-related content, to shift their contributions towards coordination rather than production work, and to perform maintenance work such as reverting vandalism. These results suggest that group influence can play an important role in maintaining the health of online communities, even when such communities are putatively self-directed peer production systems.

WikiSym English 2009 In the paper we investigate an organizational practice meant to increase the quality of commons-based peer production: the use of template messages in wiki-collections to highlight editorial bugs and call for intervention. In the context of SimpleWiki, an online encyclopedia of the Wikipedia family, we focus on {complex}, a template which is used to flag articles disregarding the overall goals of simplicity and readability. We characterize how this template is placed on and removed from articles and we use survival analysis to study the emergence and successful treatment of these bugs in the collection. Copyright 0 0
Wikis to support the "collaborative" part of collaborative learning Larusson J.A.
Alterman R.
International Journal of Computer-Supported Collaborative Learning English 2009 Prior research has highlighted the value of using wikis to support learning. This paper makes the case that the wiki has several properties that are particularly amenable for constructing applications that support the "collaborative" part of a variety and range of different time/different place student collaborations. In support of the argument, the paper presents the WikiDesignPlatform (WDP). The WDP supplies a suite of awareness, navigation, communication, transcription, and analysis components that provide additional functionality beyond the standard wiki feature set. Two case studies are presented, which have different coordination, communication, and awareness requirements for the "collaborative" part of the students' collaborative learning activities. The evidence shows that under both conditions, a prefabricated wiki provides a sufficiently rich intersubjective space that adequately supports the students' collaborative work. © International Society of the Learning Sciences, Inc.; Springer Science + Business Media, LLC 2009. 0 0
Harnessing the wisdom of crowds in wikipedia: Quality through coordination Aniket Kittur
Kraut R.E.
English 2008 Wikipedia's success is often attributed to the large numbers of contributors who improve the accuracy, completeness and clarity of articles while reducing bias. However, because of the coordination needed to write an article collaboratively, adding contributors is costly. We examined how the number of editors in Wikipedia and the coordination methods they use affect article quality. We distinguish between explicit coordination, in which editors plan the article through communication, and implicit coordination, in which a subset of editors structure the work by doing the majority of it. Adding more editors to an article improved article quality only when they used appropriate coordination techniques and was harmful when they did not. Implicit coordination through concentrating the work was more helpful when many editors contributed, but explicit coordination through communication was not. Both types of coordination improved quality more when an article was in a formative stage. These results demonstrate the critical importance of coordination in effectively harnessing the "wisdom of the crowd" in online production environments. Copyright 2008 ACM. 0 4
Incentives to Contribute in Online Collaboration: Wikipedia as Collective Action Benjamin K. Johnson International Communication Association, 58th Annual Conference, Montreal, Quebec 2008 Wikipedia is an online encyclopedia created by volunteers, and is an example of how developments in software platforms and the low cost of sharing and coordinating on the Internet are leading to a new paradigm of creative collaboration on a massive scale. The research presented here addresses the questions of why individuals choose to give away their time and effort and how the challenges associated with collective action are addressed by Wikipedia’s technologies, organization, and community. Interviews with editors of the encyclopedia were used to identify what personal gains and other motivations compel contributors, what challenges to collaboration exist, and what technological and social structures aid their ability to create a freely available repository of human knowledge. The paper suggests that the free encyclopedia is at once both a traditional instance of collective action requiring coordination and strong incentives and an instance of networked public goods that result through boundary crossing made possibly through extremely low barriers to sharing. 0 0

Socs: Increasing social and group awareness for wikis by example of Wikipedia Claus Atzenbeck
Hicks D.L.
WikiSym 2008 - The 4th International Symposium on Wikis, Proceedings English 2008 Many wikis provide good workspace awareness. Users see quickly what changes have been made or get notified about modifications on selected pages. However, they do not support a more sophisticated social or group awareness. Being aware of social structures is important for collaborative work. Adequate tools permit team members to reflect upon their and others' roles, detect and solve related conflicts in good time, and provide a means to communicate team developments. This makes such applications an effective means for new collaborators (to understand the team), long term team members (to see what is going on), and team coordinators (to manage teams and identify potential problems). This becomes especially important for fragile, large, or ad hoc virtual teams as we find around many wikis, such as Wikipedia. Furthermore, we argue that social and group awareness increases the quality of articles indirectly and is beneficial for both experts and novice users. We introduce Socs, a prototype that permits authoring social structures using spatial hypertext methods via a so-called "social space". It serves as a means to express, store, and communicate social information about people, such as wiki authors. Furthermore, Socs integrates a Web browser and the system-wide address book that act as sources for the social space and as a basis for sophisticated awareness services. Socs provides awareness about the authors of a wiki page and which of them are part of the user's structure on the social space, those that are of special interest to the user. This creates implicitly recommendations about wiki pages (because users get notified when wiki pages are authored by known people), provides the basis of interpreting the authors' intentions (because users become aware of who wrote the articles), and foster communication (because users may want to discuss those article with whom they know). 0 0
