    Are anonymity-seekers just like everybody else? An analysis of contributions to Wikipedia from Tor

    Full text link
    User-generated content sites routinely block contributions from users of privacy-enhancing proxies like Tor because of a perception that proxies are a source of vandalism, spam, and abuse. Although these blocks might be effective, collateral damage in the form of unrealized valuable contributions from anonymity seekers is invisible. One of the largest and most important user-generated content sites, Wikipedia, has attempted to block contributions from Tor users since as early as 2005. We demonstrate that these blocks have been imperfect and that thousands of attempts to edit on Wikipedia through Tor have been successful. We draw upon several data sources and analytical techniques to measure and describe the history of Tor editing on Wikipedia over time and to compare contributions from Tor users to those from other groups of Wikipedia users. Our analysis suggests that although Tor users who slip through Wikipedia's ban contribute content that is more likely to be reverted and to revert others, their contributions are otherwise similar in quality to those from other unregistered participants and to the initial contributions of registered users.Comment: To appear in the IEEE Symposium on Security & Privacy, May 202

    Our vision for the DeWitt Wallace Library of 2020 is to expand and build up our current vibrant and active space for engaging scholars. We want a library that contributes to the transformative experience for all students as well as a space that will attract faculty to utilize our space, resources, and expertise for collaborating on digital projects. We want to continue to be a community gathering space where all points of view can be shared and civil discussions can take place. We want to be a welcoming center of learning and understanding

    The Role of Information Visualization (InfoVis) in creating Multi-dimensional View of Student Report System with the use of Business Intelligence

    Get PDF
    Information Visualization (InfoVis) deals with data that is usually abstract, high-dimensional, and structured in a complex way. InfoVis enable viewer to gain knowledge about the internal structure of the data and causal relationship in it. Normally, it’s compact graphical presentation and user interface for manipulating large numbers of items and possibly extracted from far larger datasets. Parallel to this, InfoVis enables users to make discoveries, decisions, or explanations. By implementing the features of InfoVis to the student coursework reporting, it will help students in decision making of their studies, explanations on their academic performance, and increasing their interest and awareness to their academics performances

    Orienteering in Knowledge Spaces: The Hyperbolic Geometry of Wikipedia Mathematics

    In this paper we show how the coupling of the notion of a network with directions with the adaptation of the four-point probe from materials testing gives rise to a natural geometry on such networks. This four-point probe geometry shares many of the properties of hyperbolic geometry wherein the network directions take the place of the sphere at infinity, enabling a navigation of the network in terms of pairs of directions: the geodesic through a pair of points is oriented from one direction to another direction, the pair of which are uniquely determined. We illustrate this in the interesting example of the pages of Wikipedia devoted to Mathematics, or “The MathWiki.” The applicability of these ideas extends beyond Wikipedia to provide a natural framework for visual search and to prescribe a natural mode of navigation for any kind of “knowledge space” in which higher order concepts aggregate various instances of information. Other examples would include genre or author organization of cultural objects such as books, movies, documents or even merchandise in an online store

    Favecity: a visual exploration of city travel information

    Get PDF
    Web 2.0 provides a great environment for interactive information sharing and collaboration. We are no longer to receive information passively. On the contrary, everyone can contribute content and share personal experiences. It is a perfect social media for travelers to be connected. faveCITY is a visual exploration of what do people think and how do they feel about their favorite cities. It collects users\u27 opinions about the city such as city emotion, favorite city feature, best season to visit and a souvenir recommendation. The goal of this project is to combine Web 2.0 features with information visualization to create an information-sharing platform for city travelers. By visualizing these data, it could provide users unique travel advices, such as which city is the most popular travel destination right now, which city is the most romantic city etc. Furthermore, the platform is interactive and the data is live which means the results could be changed in real time

    A Web GIS-based Integration of 3D Digital Models with Linked Open Data for Cultural Heritage Exploration

    Get PDF
    This PhD project explores how geospatial semantic web concepts, 3D web-based visualisation, digital interactive map, and cloud computing concepts could be integrated to enhance digital cultural heritage exploration; to offer long-term archiving and dissemination of 3D digital cultural heritage models; to better interlink heterogeneous and sparse cultural heritage data. The research findings were disseminated via four peer-reviewed journal articles and a conference article presented at GISTAM 2020 conference (which received the ‘Best Student Paper Award’)

    Visualization of Co-authorshipin DIT Arrow

    With the popularization of information technology and the unprecedented development of online reading, the management and service of the library are facing severe challenges; the traditional library operation mode has been challenging to optimize the service. At the same time, there is also a fatal impact on library collection and systematic management, however, with the development of visualization techniques in management and service, the library can alleviate the effect of the current network information basically, which achieves the intellectual development of library field. This study empirically provides the evidence to indicate that the force directed layout has the statistically significant performance than the radial layout for visualization of co-authorship in DIT Arrow repository based on the results of surveys
