This document discusses using wikis and semantic wikis for knowledge management. It begins with an introduction to the Centre for Public Administration Research and Open Knowledge Austrian Chapter. The agenda then outlines discussing IT and knowledge management, wikis, semantic wikis, and providing an example and conclusion. It describes wikis as being socially driven software that allows for collaborative knowledge creation. Semantic wikis add structured data capabilities to traditional wikis through attributes, forms, templates and filters. An example semantic wiki project is provided, the Vienna History Wiki, which allows structured querying of data. The document argues that semantic wikis can function as a knowledge management system by bringing together unstructured text, structured data, semantic web standards and various use cases.

Wikis and Web 2.0 – „Wikimania“
wikis became well-known through Wikipedia
technologically, nothing groundbraking
Hypertext system, usually with database
simple user interface, full text search
social software
everyone can make changes: initial idea of WWW!
wisdom of the crowd
shared knowledge creation and quality management
knowledge creation „on the fly“
no need to pre-define structure
links to non-existing pages generate ideas for others
Wiki Software:
> 100 Wiki engines on www.wikimatrix.org
Most of them Open-Source: no license cost
some like MediaWiki very stable with big community

Wiki vs. Document Management
Documents = DMS
Word
Excel
PowerPoint
PDF
Approval
Electronic Signature, User rights
(File system), Sharepoint, Fabasoft, Alfresco…
Content = Wiki
Content of documents
Text with categories
Database functions with forms
Document upload as an exception

Wiki vs. Content Management
Control = CMS
Access control on different content types
(Filesystem), Sharepoint, Drupal, Typo3, Joomla…
Transparency = Wiki
Everyone can view/edit everything
Restrictions on actions (who can view/edit), not on content types (what)
Changes visible
Easy rollback
Advantage: enables cultural change!

Strenghts and Weaknesses of Wikis
Wikis are great for text…
easy to use, easy to edit
full text search
Categories to organise pages

Wikis have weaknesses for knowledge management!
no data, only text: 995 32
no relations, just links: Tbilisi —> Krakow
no querying of data
lack of structure leads to manual effort
manual edited lists (List of danube bridges, list of Autrian museums by city)

Semantic MediaWiki
leaves your MediaWiki installation intact
no patching, just a (bunch of) MW extension(s)
already existing unstructured content can stay as it is or be transformed
gives you all the tools you need for a collaborative web database
entering data and text
representing data and text within the wiki
visualise data
re-use/export data outside the wiki
everything is done through configuration
Attributes, Forms, Templates, Filters… are wiki pages

Don underestimate organizational success factors
content that users need
not to be confused with content that organization whishes for!
culture of trust and appreciation
everybody can see everything and change everything
users can‘t do anything wrong – errors can be undone easily
motivation and pressure
managers need to be role models and actively support the project
no redundant content: turn off alternative sources!
obligations to use the wiki
quantity and quality of content
Initial content is important! no-one feels at home in empty rooms
usability und fun
design, acces to wiki, (single-sign-on, RSS-feeds, intranet)
forms for data input, avoid too much wikitext for regular users
