Outline! Structured versus unstructured data
– Mediawiki – Wikpedia: Categories – Semantic Mediawiki: Forms, relations
! Semantic – why, what – Topic Maps versus Semantics
! Goal of collaborative working – just the information you want – online for "day-to-day" work
! UNIK as an information hub – for students – for the general public – for researchers
! Challenges ! Summary

MediaWiki as in Wikipedia++! All context is online available ! Links included to jump between topics
– Reasonably easy to write a page with hyperlinks ! Online collaboration (everybody) ! Structure through Categories
4
what if you introduce a new category for your web?
static content in pages

The Semantic MediaWiki
! Build as an extension to MediaWiki – same syntax, writing… – Links included to jump between topics – Online collaboration (everybody)
! Query (search) and dynamic pages ! Hierachy
5
dynamic pages through 'search'

Basics of Semantics
! Hierachy – Classes – relations
! Tripple store – UNIK has Education – Education consists of Courses – Courses are composed by Lectures

«There is no such thing as a free lunch»
Advantages ! dynamic pages, created by
«ask» ! always updated ! working tool ! relations between topics ! presentation and notes
combined
11
Disadvantages ! Think structured ! Wiki language ! first version takes
longer times ! redraw pictures ! Math rendering

Conclusions
! The world is moving towards «user generated content»
! Structure through – search (internal semantics) – Semantics (hierachies, Tripples)
! UNIK and UNIKUM – hubs for networking
! online working modus – sharing, cooperation
! needs an initial effort – structured thinking – wiki «language»
