Talk before you type: coordination in Wikipedia

  1. 1. Talk Before You Type: Coordination in Wikipedia Authors : Fernanda B. Viégas, Martin Wattenberg, Jesse Kriss, Frank van Ham Visual Communication Lab, IBM Research HICSS-40, 2007 # citations at April, 19 2010 from Google Scholar: 116 Presenter: Marco Frassoni SoNet group, http://sonet.fbk.eu
  2. 2. SoNet Research Meetings These slides were used for an internal presentation of the SoNet group. Every week, one member of the SoNet group presents a research papers to the other members. The mentioned paper(s) are hence written by other researchers. Being internal presentations, these slides might be a bit rough and unpolished. You can find more information (including this presentation) about the SoNet group at http://sonet.fbk.eu
  3. 3. Research topic & questions This paper describes the results of an empirical analysis of Wikipedia and discusses ways in which the Wikipedia community has evolved as it has grown. It contrasts findings with an earlier study [1] and present three main results. <ul><li>the community maintains a strong resilience to malicious editing, despite tremendous growth and high traffic.
  4. 4. the fastest growing areas of Wikipedia are devoted to coordination and organization.
  5. 5. it focuses on a particular set of pages used to coordinate work, the “Talk” pages finding that these pages serve many purposes, notably supporting strategic planning of editing. </li></ul>
  6. 6. Compare & contrast <ul>Since the first study [1] they made, Wikipedia has grown enormously. This dramatic change in scale is clearly visible through the application of history flow diagrams (see Figure 1), valuable tool for providing a clear overview of the editing activity in Wikipedia (as for “edit wars”, see Figure 3). These diagrams have been used to analyze a random sample (~ 5%) of article pages taken from an entire dump (i.e. a file from that included all pages - except for deleted pages - along with full revision histories) of the English Wikipedia. </ul>
  7. 7. Compare & contrast One of the main results of [1] was that Wikipedia showed remarkable resilience in the face of malicious edits. A statistical can of the sample collected for this research (eg SAMPLE05) shows that the basic fast-repair characteristics of Wikipedia remain strong. Results are presented in the following tables: These findings suggest that the community maintains a strong resilience to vandalism and malicious editing, despite its tremendous growth, high traffic and having became a high-value target.
  8. 8. How has Wikipedia grown? <ul>Investigating growing patterns can be worthy to understand the way Wikipedia community is evolving. Wikipedia is divided into several sections (namespaces) each serving a special purpose. To investigate growing patterns, researchers focused on eight namespaces and their evolution over time (see Figure 5) </ul>
  9. 9. How has Wikipedia grown? User Talk pages registered the fastest growing in the considered time-span (see Table 4). Moreover, even focusing only to the two namespaces directly related to the encyclopedic content of Wikipedia (eg Main and Talk namespaces), the number of articles' discussion pages has grown faster than the number of articles' pages. <ul>This pattern echoes the tendency of active Wikipedians to move from having a local focus—editing individual articles—to a more high-level concern for the quality of content and the health of the community, as described by Bryant et al. [3]. </ul>
  10. 10. Talk pages To better understand the increase in coordination-related pages, researchers decided to examine one of these categories, the articles' talk pages. In Viégas et al, Talk pages were characterized as places where conflict was resolved [1]. While it is true that they serve this function, a closer reading of the Talk pages indicates they play an important role in planning and other types of coordination as well. Some basic statistics behind Talk pages: Non-empty Talk pages exist for 14.5% of the article pages in the dump. Heavily edited articles and Talk pages go hand in hand. While the average edits per page in Wikipedia is roughly 15 (median = 2), around 94% of the pages with more than 100 edits have related Talk pages. Conversely, articles with associated Talk pages have, on average, 5.8 times more edits and 4.8 times more users than articles without.
  11. 11. Talk pages analysis Methodology: manual coding of 25 Talk pages, belonging to Wikipedia articles, chosen by the research among all the others. Each Talk page has been coded by two researchers, and their results compared to ensure reliability. A Talk page is divided into posts, styled with signatures, indentation and titled by discussion topics. An algorithm was developed to detect automatically posts in a Talk page and determine the number of single post: for the algorithm a post is everything on the Talk page which is followed by a signed user name, an horizontal rule or a new indentation level. Wikipedia admits to archive old posts on the Talk page in talk archives. For the purpose of this research, only not archived Talk pages have been analyzed.
  12. 12. Posting dimensions <ul><li>Requests/suggestions for editing coordination
  13. 13. Requests for information
  14. 14. References to vandalism
  15. 15. References to Wikipedia guidelines and policies
  16. 16. References to internal Wikipedia resources
  17. 17. Off-topic remarks
  18. 18. Polls
  19. 19. Requests for peer review
  20. 20. Information boxes
  21. 21. Images
  22. 22. Other </li></ul>Researchers identified 11 coding dimensions which are not mutually exclusive, hence a single post could be coded in more than one dimension. Posting dimensions are:
  23. 23. Coding findings Requests for coordination were, by far, the most common kind of posting, accounting for over half of the contributions on Talk pages (see table 7). This establishes the crucial strategic role that Talk pages serve in Wikipedia. Contributors use Talk pages to discuss their editing activities in advance, to ask for help, and to explain the reasons why they think specific changes should be made. Next in frequency were requests for information, which occurred once in every ten posts. Such requests are usually made by visitors who have no intention of editing the associated article and they suggest the use of Talk pages as a place to tap into expert knowledge of specific topics.
