Wikis Presentation by Stephanie Guerdan, Jason Mooney, Clair Hann, Clare McKendry, and Kaitlin Healy
Introduction • What is a Wiki? A wiki is a piece of server software which allows a group of people collaborate on a website. It uses a simple markup language of only text and links. • Wiki” is Hawaiian for the word “fast” • It is also said to be an acronym for “What I Know Is” • Wiki content is written and edited by users constantly
Background • A wiki is a page or collection of Web pages designed to enable anyone who accesses it to contribute or modify content, using a simplified markup language. • Markup language is a type of code (like html, for example) that gives instructions on how text should be displayed. • The first wiki software was called WikiWikiWeb and was created by Ward Cunningham and published in 1995. • The best known Wiki is the encyclopedic wiki page Wikipedia.org , but hundreds of wikis exist for various subjects.
Pros • They allow anyone to easily edit any page. No HTML knowledge is necessary to edit pages. • Any web browser can be used to edit a page. • Errors such as broken links, spelling errors and factual errors are quickly and easily corrected by users. Insightful comments are also easily added to any page. • Community users can easily catch and correct malicious content. • Comments by users are integrated directly into the web page. • Key words are automatically highlighted by colored text and linked to another wiki page. • Wikis are free.
Cons • Wikis are vulnerable. All the data on a wiki can be destroyed by automated attacks. • Pages are easily tampered with and vandalized. • Pages and edits are not reviewed before they are posted. • Wikis rely on readers to correct erroneous content which may take a long time if the page is not popular. Therefore less popular topics or pages on wikis are less reliable. • It it difficult to ban single attackers from posting maliciously. Malicious comments are corrected, not prevented.
The Most Popular Criticisms of Wikis • Anyone can edit an entry • This leads to: • Wrong Information • Sometimes articles are written by experts but sometimes they are not • Misinformation • The deliberate placement of wrong information; may be hard to spot • Vandalism
Opinion • Wiki’s provide an easy and fast source for research and projects. • Students working on research reports can easily contribute their new found results. • Unfortunately, the ease of altering doesn’t always make Wiki’s reliable. Students can create wiki’s on anything. If its doesn’t already exist, one can be created to prove a point, regardless of accuracy.
