Definition of wikis
A community-developed documentation project
“ A piece of server software that allows users to freely create and edit Web page content using any Web browser. Wiki supports hyperlinks and has a simple text syntax for creating new pages and crosslinks between internal pages on the fly.” -- http://wiki.org/wiki.cgi?WhatIsWiki
“ A wiki is a type of website that allow users to easily add and edit content and is especially suited for collaborative writing. The name is based on the Hawaiian term wiki, meaning "quick", "fast", or "to hasten" (Hawaiian dictionary).” -- http://en.wikipedia.org/wiki/Wiki
Makao, famous Hawaiian runner

So, what are wikis used for?
A wiki is an informational resource , like a reference manual, encyclopaedia, or handbook
It amasses to a group of web pages that allows users to add content and also allows others to edit the content:
It relies on cooperation, checks and balances of its members, and a belief in sharing of ideas
This creates a community effort in resource and information management, disseminating the 'voice' amongst many instead of concentrating it upon few
Wikis are being used in many ways, including the Wikipedia , a highly used, online, free-access encyclopaedia

History (adapted from the Wikipedia)
The WikiWikiWeb was the first wiki, established by Ward Cunningham in March 1995. He invented the wiki name and concept, and implemented the first wiki engine. Cunningham coined the term wiki after the "wiki wiki" or "quick" shuttle buses at Honolulu Airport. Wiki wiki was the first Hawaiian term he learned on his first visit to the islands, when the airport counter agent directed him to take the wiki wiki bus between terminals. According to Cunningham, "I chose wiki-wiki as an alliterative substitute for 'quick' and thereby avoided naming this stuff quick-web."
In the late 1990s, wikis increasingly were recognised as a promising way to develop knowledge bases , and this potential inspired the founders of the Nupedia encyclopedia project, Jimbo Wales and Larry Sanger , to use wiki technology as a basis for an electronic encyclopedia: Wikipedia was launched in January 2001.
In the early 2000s, wikis were increasingly adopted in the enterprise as collaborative software . Common uses included project communication, intranets and documentation, initially for technical users. In December 2002, Socialtext launched the first commercial open source wiki solution. Open source wikis such as MediaWiki , Kwiki and TWiki grew to over 1 million downloads on the Sourceforge repository by 2004.
Today some companies use wikis as their only collaborative software and as a replacement for static intranets. There is arguably greater use of wikis behind firewalls than on the public internet.

Some other uses of wikis
Wikis are being used for:
online encyclopaedias
free dictionaries
book repositories
event organisation
software development
writing research papers
project proposals

Typical wiki page

Entering information
Anyone can edit an existing wiki article
If an article does not exist on a particular topic, you can create it
If someone messes up an article (deliberately or erroneously), there is a revision history so you can revert the contents
“ If removing paint were as easy as painting, we’d only have nice graffiti!”

Updating information
When you see an article, click on “Edit”
Type in the new text, click on “Save Page”
Simple “markup”, e.g.
[[NUIM]] -> link to National University of Ireland Maynooth article
This is '''important''' -> This is important

Templates
Templates are used within articles to provide a consistent look to the content placed into them
Templates can also provide a structure for entering data, so that it is easy to extract metadata about the topic of an article:
e.g. from a template field called “population” in an article about Galway
e.g. emoticons

Why do people contribute to wikis?
People like to store knowledge
Can see what articles a person has created
People like to show that they know things!
There's a permanent record of what a user has contributed to a wiki site
People like to fix mistakes and fill in gaps in underdeveloped articles
Sometimes it’s those egos again 

Some Irish wiki sites
www.wiki.ie – Wiki Ireland
The aim of Wiki Ireland is use wiki technology to create a knowledge store for Ireland's culture and heritage

What is Wiki Ireland?
Wikipedia is an excellent resource that has over a million articles, with 100s of articles about or related to Ireland
But in a general encyclopaedia, there will be local knowledge that cannot be included if it is non-notable or “obscure”
Wiki Ireland aims to be a knowledge store for...

Problems with traditional wikis
Structured access
Information reuse
JohnGrisham He is the author of PelicanBrief . He lives in Mississippi. He writes a book each year. He is published by RandomHouse .
Structured access:
Other books by JohnGrisham (navigation)
All authors that live in Europe? (query)
Information reuse:
The authors from RandomHouse (views)
And what if I don't speak English? (translation)

Personal wikis
Enabling personal information management
Should be very simple, very fast, very usable
“ Note-taking on steroids”
Examples include Tomboy, WikidPad, VoodooPad
Notes, links, categories (to do lists, appointments)
Popularity: simplicity, usability

What are semantic wikis?
A wiki that has an underlying model of the knowledge described in its pages:
Semantic wikis allow to capture or identify further information about the pages (metadata) and their relations
Knowledge model available in a formal language, so that machines can (at least partially) process and reason on it
A semantic wiki would be able to capture that an "apple" article is a "fruit" (through an inheritance relationship) and present you with further fruits when you look at apple
Some are used for personal knowledge management, others aimed at KM for communities

Structural and content metadata in semantic wikis

Semantic wiki prototypes
At least 22 semantic wiki prototypes to date
For a comprehensive list see:
wiki.ontoworld.org/index.php/Semantic_Wiki_State_Of_The_Art or www.cfcl.com/rdm/MBD/mbd_sem_wiki.php
Semantic wikis are aiming at collaboration:
Typically web based (two modes)
Semantic personal wikis are aiming at personal information management:
Typically a desktop application (one mode)

Information reuse in SemperWiki

Semantic MediaWiki
“ The Semantic MediaWiki is an extension to the MediaWiki software, which allows every user to make information more accessible to computer programs (including the ask query and the triple search available in SMW itself), which in turn makes it easier for humans to search or further use this information.”
Semantic MediaWiki offers two means to make information about a page more explicit:
Categorisation of links (relations between pages)
Typed attributes (of a page)
Users can classify the “type” of links, e.g. making a relationship such as “capital of” between Berlin and Germany explicit:
... [[capital of::Germany]] ... resulting in the semantic statement "Berlin" "capital of" "Germany" .
On the page Berlin , users can explicitly define its population by writing:
... the population is [[population:=3,993,933]] ... resulting in the semantic statement "Berlin" "has population" "3993933" .

Wiki guide
The Wikipedia project and Wiki Ireland both use the MediaWiki system
As mentioned, there are a number of different wiki platforms but most have similar methods of doing things
We will now show you how to create and edit wiki pages using MediaWiki
Try it out at www.wiki.ie

How to edit a page
To start editing a page, click “ edit ”, either at the top of the page (which lets you edit the entire page) or towards the right within the page (which lets you edit a section of the page only, which is at times less overwhelming).
Once in the editing mode, you can preview the page before finalising it by clicking Show Preview at the bottom of the page, beneath the editing box. This also lets you get familiar with the results of the commands. After you have decided on your changes, click Save Page . Be sure to save your changes!
To see who has previously edited a page and when, at any time click “ history ” at the top of the page. To talk about a page, click “ discussion ” at the top of the page.

The quick toolbar
Rather than writing commands by hand, you can use the toolbar as a shortcut. Leaving your cursor over any of the buttons will explain what it does. While not all of the formatting options can be accessed through the toolbar (the rest must be written out by hand), you can edit by highlighting the text and clicking a command button.
Alternatively, you can just click any button and it will write the command with generic text which you can then go in an edit. For example, clicking the first button, the “bold text button”, will write ‘‘‘Bold text’’’. You can then replace the words ‘bold text’ with whatever words you want to embolden.
Spacing is a bit tricky. You must hit “enter” twice in editing for it to show up once in the page. The command <br> can also be used to move the text downwards.

Creating a new page
In order to have all pages connect to one another, it is best to create a page by first creating a link to it in another, previously established page. To do so, edit the page where you’d like to link the new page and type [[New page]] where “New page” will be the title of your new page. Please make the title of your page fairly specific (e.g. “Galway Rowing Club”, not “Rowing Club”)
After you have created a link and saved, you can open the new page via its link, which should appear in red , indicating that it has not yet been developed. You can make requests for “Wanted” pages to be written by creating these red links. Clicking on a red link will immediately open the editing box for that page.

Adding an image
In addition to adding textual information and being able to modify it, you can also add other files, including images, to your pages. All files that are placed inside of a page, must, however, first be uploaded as separate files to the wiki. Do this by first clicking “ Upload file ” in the lower left-hand frame in the section labelled “toolbox”.
Then you can add a file by clicking Browse , finding the desired file, checking the copyright compliance box, and then choosing to Upload File at the bottom of the page.
Once the file has been uploaded, the markup to display the image will be shown, e.g. [[Image:MyPicture.jpg]]
