  2. 2. Today’s Goals <ul><li>Understand the premise and purpose of Wikipedia </li></ul><ul><li>Understand the strengths and limitations of Wikipedia </li></ul><ul><li>Learn how to evaluate Wikipedia articles </li></ul><ul><li>Practice </li></ul>
  3. 3. Wikipedia <ul><li>Is a multilingual, Web-based, free-content encyclopedia project. </li></ul><ul><li>Is written collaboratively by volunteers from all around the world. Anyone with internet access can make changes to Wikipedia articles. </li></ul><ul><li>Has 400 million unique visitors monthly as of March 2011. </li></ul><ul><li>There are more than 91,000 active contributors working on more than 25,115,592 pages in more than 270 languages. As of today, there are 3,755,600 articles in English. </li></ul><ul><ul><li>English Wikipedia right now </li></ul></ul><ul><li>Has no advertising—all donations & grants </li></ul>
  4. 4. Strengths of Wikipedia <ul><ul><li>Up-to-the-minute, often excellent coverage on topical events (unlike traditional paper encyclopedias). </li></ul></ul><ul><li>In theory, it is eventually is self-correcting-- errors to Wikipedia are usually corrected within seconds, rather than within months as it would be for a paper encyclopedia. </li></ul><ul><li>Current affairs articles, as well as older articles being edited, might be updated hundred of times an hour. </li></ul><ul><li>Wikipedia's neutral point of view policy makes it an excellent place to gain a quick understanding of topics. </li></ul><ul><li>Censorship, or imposing &quot;official&quot; points of view is extremely difficult to achieve and almost always fails after a time. </li></ul><ul><li>One of few sites on the web even attempting neutral, objective, encyclopedic coverage of popular culture. </li></ul>
  5. 5. and more Strengths… <ul><ul><li>There are many non-Western writers, so has many topics not covered fully in other English encyclopedias. </li></ul></ul><ul><ul><li>Rating system in place. </li></ul></ul><ul><ul><li>You can find interesting articles on some obscure town or a bizarre hobby written by actual residents and practitioners. People with a passion for a field or topic are those who contribute. See Ocean sunfish </li></ul></ul><ul><ul><li>Information in Wikipedia is hyperlinked, not linear (like a textbook). </li></ul></ul>
  6. 6. It’s biggest strength… <ul><li>It is a good place to start research on a topic you know little or nothing about. Once evaluated for authoritativeness (we’ll get to that!) it will give you: </li></ul><ul><ul><li>Key names, dates </li></ul></ul><ul><ul><li>Key words, events </li></ul></ul><ul><ul><li>Links to primary sources </li></ul></ul><ul><ul><li>Links to verifiable sources </li></ul></ul><ul><ul><li>Great source for images! </li></ul></ul><ul><li>And then you can begin the research process. </li></ul>
  7. 7. Criticisms <ul><li>Wikipedia's open editing also means that any given article may be, at any given moment, in a bad state, such as in the middle of a large edit, or a controversial rewrite. </li></ul><ul><li>Notable criticisms include that its open nature makes it not authoritative and unreliable (see Reliability of Wikipedia ). </li></ul><ul><li>Obvious or subtle vandalism. </li></ul><ul><li>Susceptible to attempts by outsiders (or insiders) with an agenda to place a spin on articles. </li></ul><ul><li>Edit “wars.” </li></ul>
  8. 8. Who contributes what? <ul><li>Anyone–you do not need specialized qualifications to contribute (a plus and a minus!—yet many professionals do contribute. However some articles (see Martin Luther King, Jr .) are locked. </li></ul><ul><li>Articles cover existing knowledge, not original research. </li></ul><ul><li>Most of the articles can be edited by anyone. </li></ul><ul><li>Substandard or disputed information is subject to removal. </li></ul><ul><li>Need not worry about accidentally damaging Wikipedia when adding or improving information, as other editors are always around to advise or correct obvious errors. </li></ul>
  9. 9. The reality? <ul><ul><ul><li>May contain false or debatable information. </li></ul></ul></ul><ul><ul><ul><li>Many articles have much more verifiable, up-to-date, authoritative information than text encyclopedias. </li></ul></ul></ul><ul><ul><ul><li>Many articles start their lives as partisan; and, after a long process of discussion, debate, and argument, they gradually take on a neutral point of view reached through consensus. </li></ul></ul></ul><ul><li>Facts should always be checked against many sources. </li></ul><ul><li>General encyclopedias are not cited for research. </li></ul>
