|Lifecycle-based evolution of features in collaborative open production communities: The case of wikipedia||Ziaie P.
|ECIS 2013 - Proceedings of the 21st European Conference on Information Systems||English||2013||In the last decade, collaborative open production communities have provided an effective platform for geographically dispersed users to collaborate and generate content in a well-structured and consistent form. Wikipedia is a prominent example in this area. What is of great importance in production communities is the prioritization and evolution of features with regards to the community lifecycle. Users are the cornerstone of such communities and their needs and attitudes constantly change as communities grow. The increasing amount and versatility of content and users requires modifications in areas ranging from user roles and access levels to content quality standards and community policies and goals. In this paper, we draw on two pertinent theories in terms of the lifecycle of online communities and open collaborative communities in particular by focusing on the case of Wikipedia. We conceptualize three general stages (Rising, Organizing, and Stabilizing) within the lifecycle of collaborative open production communities. The salient factors, features and focus of attention in each stage are provided and the chronology of features is visualized. These findings, if properly generalized, can help designers of other types of open production communities effectively allocate their resources and introduce new features based on the needs of both community and users.||0||0|
|Open2Edit: A peer-to-peer platform for collaboration||Zeilemaker N.
|2013 IFIP Networking Conference, IFIP Networking 2013||English||2013||Peer-to-peer systems owe much of their success to user contributed resources like storage space and bandwidth. At the same time, popular collaborative systems like Wikipedia or StackExchange are built around user-contributed knowledge, judgement, and expertise. In this paper, we combine peer-to-peer and collaborative systems to create Open2Edit, a peer-to-peer platform for collaboration.||0||0|
|Decentralized collaboration with a peer-to-peer wiki||Alan Davoust
|Proceedings of the 2012 International Conference on Collaboration Technologies and Systems, CTS 2012||English||2012||We report our experience using a peer-to-peer (P2P) wiki system for academic writing tutorials. Our wiki system supports a non-traditional collaboration model, where each participant maintains their own version of the documents. The users share their contributions in the P2P network, which allows them to be exposed to multiple viewpoints, and to reuse each other's work. We collected and analyzed the contributions of the participants to these tutorials, and the results demonstrate the value of this collaboration model. In particular, we found the popularity of a document in the system is correlated with its quality, and the similarity between contributions of peers is a good predictor of future similarities. These properties provide helpful criteria for users to identify valuable material for reuse.||0||0|
|University futures: Wikipedia uni, core-periphery reversed, incremental managerialism or bliss for all?||Inayatullah S.||On the Horizon||English||2012||Purpose: The purpose of this paper is to overview the futures of the university by analyzing critical drivers. It also aims to assess drivers identified a decade ago on university futures. Design/methodology/approach: The paper reviews drivers, trends and scenarios. Findings: The paper finds first, globalization will likely continue but innovation will move to Chindia. Second, democratization has resulted by not as imagined a decade ago, rather, peer-to-peer or web 2.0 has changed the game. Three new scenarios are articulated: Wikipedia university; core-periphery reversed and incremental managerialism. Bliss for all remains an outlier. Practical implications: Asian-Pacific universities instead of adopting the used future of the core will find it wiser to innovate and create new visions as well as to develop new global ranking systems. Social implications: Traditional universities are the likely dinosaurs unable to thrive in a dramatically changing world. Increasing inequity in traditional western universities will likely further devalue higher education. New models of inclusion are required. Originality/value: The paper articulates new scenarios of the future, and assesses trends identified a decade ago. It provides a strategy for university administrators to navigate the challenges ahead.||0||0|
|Web 2.0-based E-learning: A probe into the application of online social networking in college freshman English curriculum||Chung L.-Y.||Advanced Materials Research||English||2012||Interaction, sharing, and connection are at the heart of Web 2.0, giving rise to innovative online media usage and the concept social networking that have transformed not only the network behavior of the masses, but also the form of online learning. In college English learning courses, Web 2.0 provides real-time and easily-accessible online resources for students to search for the information they need, granting them more autonomy in the English learning process. Meanwhile, Web 2.0-based network tools and video-sharing platform, such as Wikipedia and podcasts, provide a user-oriented and user-centered mechanism that allows personal creation, cooperative creation, interactive social networking, and peer-to-peer mutual learning, as an extension to the scope of autonomous English learning. In addition, with the rising popularity of Web 2.0-inspired social networking sites like Facebook, Twitter and blogs, the concept of social networking should also be increasingly incorporated into language education, since it promotes online interactions among English learners, while facilitating the establishment of information sharing, data query, and learning partnership in the network learning community. Thus, this project exploits Web 2.0-based online learning as the framework to design freshman English materials fusing social learning elements, for the purpose of boosting students' interests for enhanced learning effectiveness, expanding e-learning into s-learning.||0||0|

|Enhancing student learning through peer review in a wiki-based e-gallery||Trowsdale D.
|DS 69: Proceedings of E and PDE 2011, the 13th International Conference on Engineering and Product Design Education||English||2011||An important aspect of design pedagogy lies in providing students with opportunities to discuss their own and other students' work in progress with students and tutors. As a result of the introduction of computers, design work is often screen-based, submitted electronically and digitally archived thus reducing the opportunities for learning from others. An e-gallery is a virtual, on-line environment within which artists and designers can display their work. In this paper we report experiences of using an e-gallery to enhance student learning. The content of the e-gallery was generated entirely by student learners using on widely available Wiki technology, embedded within a virtual learning environment. The project is designed to give students experience of a whole product design and development process submitting work to the e-gallery at key stages. Design work is initially peer reviewed in small groups where peer-to-peer and tutor-to-learner feedback is posted and recorded. Once this group review process has been completed the e-gallery is opened for all students to browse providing opportunities to view peer projects and both peer and tutor feedback. Early experiences of running the project suggest that the opportunity for analysis and reflection upon others students' work supports deeper learning, while the open access to all learners' work in the gallery generates motivation to produce higher quality work from the early stages of the project. Future versions could also include viewing and feedback from external bodies such as businesses reviewing design work at key stages during live briefs.||0||0|
|Improved dynamic model for policy based access control||Muley R.
|International Conference and Workshop on Emerging Trends in Technology 2011, ICWET 2011 - Conference Proceedings||English||2011||The increasing popularity of peer to peer groups and the decentralized nature evolve the groups towards dynamism and self-organization. Dynamic groups like Wikipedia, F/OSS and other business communities motivate the need for dynamic multi-level access control. These self-organizing groups have special security requirements out of which Access Control mechanism is one of the essential security factors. Policy based access control mechanism is helpful in providing dynamism to the overall access control. The dynamic nature of peers joining and leaving and changing environment, increases the possibility of presence of malicious peers. To enable a group to survive one needs to tackle impact of malicious peers on the group performance. Paper includes a brief work on dynamic policy based access control and dynamic control on malicious peers. Simulation of the work is done in Peersim integrated with Prolog to test the framework in presence of static and dynamic access control. Copyright||0||0|
|STAIRS: Towards efficient full-text filtering and dissemination in DHT environments||Rao W.
|VLDB Journal||English||2011||Nowadays "live" content, such as weblog, wikipedia, and news, is ubiquitous in the Internet. Providing users with relevant content in a timely manner becomes a challenging problem. Differing from Web search technologies and RSS feeds/reader applications, this paper envisions a personalized full-text content filtering and dissemination system in a highly distributed environment such as a Distributed Hash Table (DHT) based Peer-to-Peer (P2P) Network. Users subscribe to their interested content by specifying input keywords and thresholds as filters. Then, content is disseminated to those users having interest in it. In the literature, full-text document publishing in DHTs has suffered for a long time from the high cost of forwarding a document to home nodes of all distinct terms. It is aggravated by the fact that a document contains a large number of distinct terms (typically tens or thousands of terms per document). In this paper, we propose a set of novel techniques to overcome such a high forwarding cost by carefully selecting a very small number of meaningful terms (or key features) among candidate terms inside each document. Next, to reduce the average hop count per forwarding, we further prune irrelevant documents during the forwarding path. Experiments based on two real query logs and two real data sets demonstrate the effectiveness of our solution.||0||0|
|Achieving high precisions with peer-to-peer is possible||Winter J.
|Lecture Notes in Computer Science||English||2010||Until previously, centralized stand-alone solutions had no problem coping with the load of storing, indexing and searching the small test collections used for evaluating search results at INEX. However, searching the new large-scale Wikipedia collection of 2009 requires much more resources such as processing power, RAM, and index space. It is hence more important than ever to regard efficiency issues when performing XML-Retrieval tasks on such a big collection. On the other hand, the rich markup of the new collection is an opportunity to exploit the given structure and obtain a more efficient search. This paper describes our experiments using distributed search techniques based on XML-Retrieval. Our aim is to improve both effectiveness and efficiency; we have thus submitted search results to both the Efficiency Track and the Ad Hoc Track. In our experiments, the collection, index, and search load are split over a peer-to-peer (P2P) network to gain more efficiency in terms of load balancing when searching large-scale collections. Since the bandwidth consumption between searching peers has to be limited in order to achieve a scalable, efficient system, we exploit XML-structure to reduce the number of messages sent between peers. In spite of mainly aiming at efficiency, our search engine SPIRIX resulted in quite high precisions and made it into the top-10 systems (focused task). It ranked 7 at the Ad Hoc Track (59%) and came first in terms of precision at the Efficiency Track (both categories of topics). For the first time at INEX, a P2P system achieved an official search quality comparable with the top-10 centralized solutions!||0||0|
|Human computer collaboration to improve annotations in semantic wikis||Boyer A.
|WEBIST 2010 - Proceedings of the 6th International Conference on Web Information Systems and Technology||English||2010||Semantic wikis are promising tools for producing structured and unstructured data. However, they suffer from a lack of user provided semantic annotations, resulting in a loss of efficiency, despite of their high potential. We propose a system that suggests automatically computed annotations to users in peer to peer semantic wikis. Users only have to validate, complete, modify, refuse or ignore these suggested annotations. Therefore, the annotation task becomes easier, more users will provide annotations. The system is based on collaborative filtering recommender systems, it does not exploit the content of the pages but the usage made on these pages by the users. The resulting semantic wikis contain several kinds of annotations with different status: human, computer or human-computed provided annotations.||0||0|
|Logoot: A scalable optimistic replication algorithm for collaborative editing on P2P networks||Stephane Weiss
|Proceedings - International Conference on Distributed Computing Systems||English||2009||Massive collaborative editing becomes a reality through leading projects such as Wikipedia. This massive collaboration is currently supported with a costly central service. In order to avoid such costs, we aim to provide a peer-to-peer collaborative editing system. Existing approaches to build distributed collaborative editing systems either do not scale in terms of number of users or in terms of number of edits. We present the Logoot approach that scales in these both dimensions while ensuring causality, consistency and intention preservation criteria. We evaluate the Logoot approach and compare it to others using a corpus of all the edits applied on a set of the most edited and the biggest pages of Wikipedia.||0||0|
|Mutable peer-to-peer file systems: Analysis and evaluation||Chelmis C.||1st International Conference on Advances in P2P Systems, AP2PS 2009||English||2009||Peer-to-peer networks have become extremely popular over the last decades for one major reason. They make the exchange of files between users easy and fast. Peer-to-peer systems have been proved to be the basis for the creation of worldwide networks where users exchange read-only files freely and efficiently. However, users have started using applications that need more than what the exchange of immutable files can offer. Collaborative Wikis have emerged as a phenomenon of people's behavior to communicate and collaboratively create and maintain large collections of documents. Communities that do not want to rely on centralized servers and legacy applications would benefit from using peer-to-peer systemsfor their purposes. The immutability of files that peer-to-peer systems can support however, cannot possibly serve this purpose. This paper makes three contributions towardsthe advances in theoretical foundations of P2P. It analyzes existing peer-to-peer systemssupporting mutable files and indicates their successes and failures in this direction. Itdescribes the characteristics that a mutable peer-to-peer file system should have in order to be able to support applications with characteristics of collaborative Wikis. Finally, it proposes an architecture for the creation of a new peer-to-peer system with the desirable characteristics, based on already existing systems.||0||0|
|Supporting personal semantic annotations in P2P semantic wikis||Torres D.
|Lecture Notes in Computer Science||English||2009||In this paper, we propose to extend Peer-to-Peer Semantic Wikis with personal semantic annotations. Semantic Wikis are one of the most successful Semantic Web applications. In semantic wikis, wikis pages are annotated with semantic data to facilitate the navigation, information retrieving and ontology emerging. Semantic data represents the shared knowledge base which describes the common understanding of the community. However, in a collaborative knowledge building process the knowledge is basically created by individuals who are involved in a social process. Therefore, it is fundamental to support personal knowledge building in a differentiated way. Currently there are no available semantic wikis that support both personal and shared understandings. In order to overcome this problem, we propose a P2P collaborative knowledge building process and extend semantic wikis with personal annotations facilities to express personal understanding. In this paper, we detail the personal semantic annotation model and show its implementation in P2P semantic wikis. We also detail an evaluation study which shows that personal annotations demand less cognitive efforts than semantic data and are very useful to enrich the shared knowledge base.||0||0|
|Undo in peer-to-peer semantic wikis||Charbel Rahhal
|CEUR Workshop Proceedings||English||2009||The undo mechanism is an essential feature in collaborative editing systems. Most popular semantic wikis support a revert feature, some provide an undo feature to remove any modification at any time. However this undo feature does not always succeed. Supporting the undo mechanism for P2P semantic wikis has never been tackled. In this paper, we present an undo approach for Swooki, the first P2P semantic wiki.We identify the problems to resolve in order to achieve such mechanism for P2P semantic wikis.We give the definition of the undo and the properties that must ensure. This approach allows both a revert and a permanent successful undo.||0||0|
|UniWiki: A Collaborative P2P System for Distributed Wiki Applications||Gerald Oster
|Wiki-enhanced social scribing of lectures: A case study in an undergraduate course||Sarkar S.||Proceedings - Frontiers in Education Conference, FIE||English||2009||We document how Web 2.0 tools such as Wiki can be used to enhance peer to peer learning. As is commonly known, note-taking abilities vary among the students and that bad class notes exacerbates the problem of low comprehension or even wrong understanding of essential concepts. One tempting solution to address this is to hand out instructor notes/slides to the class or to assign students to scribe each lecture, which is then shared with the class, typically through a website. This only offers a partial solution to the problem as the quality of the scribing vary from student to student and the students are essentially given expression of others' understanding. We have found that the wiki is an excellent mechanism to engage the students in a participatory, socially networked, scribing of lectures, to result in a set of comprehensive notes that the whole class helped create. The set of notes generated is greater than the sum of the individual components, and represents the collective understanding of the class.||0||0|
|SWOOKI: A peer-to-peer semantic wiki||Charbel Rahhal
|CEUR Workshop Proceedings||English||2008||In this paper, we propose to combine the advantages of semantic wikis and P2P wikis in order to design a peer-to-peer semantic wiki. The main challenge is how to merge wiki pages that embed semantic annotations. Merging algorithms used in P2P wiki systems have been designed for linear text and not for semantic data. In this paper, we evaluate two optimistic replication algorithms to build a P2P semantic wiki.||0||0|
|Scalaris: Reliable transactional P2P key/value store Web 2.0 hosting with erlang and java||Schutt T.
|Erlang'08: Proceedings of the 2008 SIGPLAN Erlang Workshop||English||2008||We present Scalaris, an Erlang implementation of a distributed key/value store. It uses, on top of a structured overlay network, replication for data availability and majority based distributed transactions for data consistency. In combination, this implements the ACID properties on a scalable structured overlay. By directly mapping the keys to the overlay without hashing, arbitrary key-ranges can be assigned to nodes, thereby allowing a better load-balancing than would be possible with traditional DHTs. Consequently, Scalaris can be tuned for fast data access by taking, e.g. the nodes' geographic location or the regional popularity of certain keys into account. This improves Scalaris' lookup speed in datacenter or cloud computing environments. Scalaris is implemented in Erlang. We describe the Erlang software architecture, including the transactional Java interface to access Scalaris. Additionally, we present a generic design pattern to implement a responsive server in Erlang that serializes update operations on a common state, while concurrently performing fast asynchronous read requests on the same state. As a proof-of-concept we implemented a simplified Wikipedia frontend and attached it to the Scalaris data store backend. Wikipedia is a challenging application. It requires - besides thousands of concurrent read requests per seconds - serialized, consistent write operations. For Wikipedia's category and backlink pages, keys must be consistently changed within transactions. We discuss how these features are implemented in Scalaris and show its performance.

|Web 2.0 as syndication||Clarke R.||Journal of Theoretical and Applied Electronic Commerce Research||English||2008||There is considerable excitement about the notion of 'Web 2.0', particularly among Internet businesspeople. In contrast, there Is an almost complete lack of formal literature on the topic. It Is important that movements with such energy and potential be subjected to critical attention, and that industry and social commentators have the opportunity to draw on the eCommerce research literature in formulating their views. This paper assesses the available information about Web 2.0, with a view to stimulating further work that applies existing theories, proposes new ones, observes and measures phenomena, and tests the theories. The primary interpretation of the concept derives from marketers, but the complementary technical and communitarian perspectives are also considered. A common theme derived from the analysis Is that of 'syndication' of content, advertising, storage, effort and identity.||0||0|
|A decentralized wiki engine for collaborative Wikipedia hosting||Guido Urdaneta
Maarten van Steen
|WEBIST ’07: Proceedings of the 3rd International Conference on Web Information Systems and Technologies||English||2007||This paper presents the design of a decentralized system for hosting large-scale wiki web sites likeWikipedia, using a collaborative approach. Our design focuses on distributing the pages that compose the wiki across a network of nodes provided by individuals and organizations willing to collaborate in hosting the wiki. We present algorithms for placing the pages so that the capacity of the nodes is not exceeded and the load is balanced, and algorithms for routing client requests to the appropriate nodes. We also address fault tolerance and security issues.||1||0|
|Scalable information sharing utilizing decentralized P2P networking integrated with centralized personal and group media tools||Guozhen Z.
|Proceedings - International Conference on Advanced Information Networking and Applications, AINA||English||2006||We proposed a collaborative information sharing environment based on P2P networking technology, to support communication among special groups with given tasks, ensure fast information exchange, increase the productivity of working groups, and reduce maintenance and administration costs in our previous work. However, for a social growing community, not only the information exchange/sharing functions are necessary, but also solutions to support users with idea and knowledge publication tools for private purpose or public use are essential. Some private message (personal idea and experience) posting tools (e.g., weblog) and group collaborative knowledge editing tools (e.g., Wikis) are used in practice; the merits of these tools have been recognized. In this paper, we propose a scalable information sharing solution, which integrates decentralized P2P networking with centralized personal/group media tools. This solution combines the effective tools, such as weblog and Wiki, into P2P-based collaborative groupware system, to facilitate infinite, growing and scalable information management and sharing for individuals and groups.||0||0|
