where the wiki name comes from
Where the Wiki name comes from?
  • Wiki Wiki Shuttle

From Wikipedia, the free encyclopedia

    • The Wiki Wiki Shuttle is a shuttle bus system at the Honolulu International Airport.
  • In the Hawaiian language "wiki" means quick, and "wiki wiki" implies very quick.
  • The shuttle's name inspired Ward Cunningham to call his new website technology "WikiWikiWeb", from which the concept of wiki software derives.

what is a wiki
What is a Wiki?
  • Wiki: Software, knowledge, community
    • A wiki Web site is a set of Web resources that can be easily and quickly created and/or edited via a Web-based interface by anyone who is allowed access.
    • One or more people are collaborating on building up a corpus of shared knowledge in a collection of interlinked Web pages.
    • A wiki Web site is accompanied with a social protocol supporting the community of users

wiki paradigm shift
Wiki paradigm shift:
  • Work in the presence of uncertainty:
    • Produce results that will be valuable in the future!
    • In the presence of the constant change globally, we are not able to predict future!
  • Reflective Practice:
    • “The thing that make us smart” (what people and computers can do together?) [Fisher, 2001]

what is wiki individual vs collective intelligence
What is Wiki: Individual vs. Collective Intelligence
  • Wiki is a new social interaction medium for publishing new form of intellectual artifacts: so called Live Documents.
  • Wikipedia isn’t great because it’s like the Britanica. The Britanica is great at being authoritative, edited, expensive, and monolithic. Wikipedia is great at being free, universal, and instantaneous.- Cory Doctorow

aspects wiki as a network
Aspects: Wiki as a network
  • Wikipedia is a small-world network
    • Small-World Network is a type of graph in which most nodes are not neighbors of one another, but most nodes can be reached from every other by a small number of hops or steps.

Sander Spek, Wikipedia: organisation from a bottom-up approach. 2006. WikiSym 2006.

  • Wikipedia is a scale-free network
    • A scale-free network is a network whose degree distribution follows a power law, at least asymptotically. That is, the fraction P(k) of nodes in the network having k connections to other nodes goes for large values of k as P(k) ~ k−γ where γ is a constant whose value is typically in the range 2<γ<3, although occasionally it may lie outside these bounds.

social tagging
Social tagging:
  • What do we do when we tag?
    • Assign one or more words, called tags, to some Web resource, usually Web page, or picture, or …
    • We are doing some mental work, work on semantics
  • Tagging vs. Classification?
    • Complementary
    • Mental cost of tagging is LOW: Large end-user community
    • Mental cost of classification is HIGH: Small teams of experts

Introduction to Wikis: Collaboration, Semantics, and Applications

Dr. Milorad Tošić, Faculty of Electronic Engineering Nis, Serbia

Abstract:Wiki is one of the concepts jointly known as Social Software and Web 2.0 that characterize a mass of (simple) services on the Web facilitating social interactions and emerging intelligence. This talk gives an introduction into multi-faceted nature of Wiki including technology, community, knowledge, and application aspects. Illustrative practical examples will be used to demonstrate Wiki experience. Collaborative Wiki Tagging is presented as one of the powerful tools for social interaction, collaboration, and knowledge accumulation. First, basic concepts are described. Then, we discuss semantics of the approach. Finally, we give practical examples of social tagging and domain-specific glossary applications. Special attention is given to two application domains: scientific community building and university teaching.
