"As We May Think" (1945)
... When data of any sort are placed in
storage, they are filed alphabetically
or numerically, and information is
found (when it is) by tracing it down
from subclass to subclass. It can be in
only one place, unless duplicates are
used; one has to have rules as to which
path will locate it, and the rules are
cumbersome. Having found one
item, moreover, one has to emerge from
the system and re-enter on a
new path. The human mind does not work
that way. It operates by association.

"As We May Think" (1945) …
... It affords an immediate step,
however, to associative indexing, the
basic idea of which is a
provision whereby any item may be
caused at will to select immediately
and automatically another. This is the
essential feature of the memex. The
process of tying two items together is
the important thing. ...

"As We May Think" (1945) …
Bush's article 'As We My Think'
(1945) is often seen as
the “origin" of hypermedia
Article introduces the Memex prototypical hypertext machine
store and access information
follow cross-references (trails)between pieces of information (microfilms)
trail blazers are those who find delight inthe task of establishing useful trails
Memex

Hypertext
Ted Nelson coined the term hypertext
founded project Xanadu in 1960
Doug Engelbart started developing the NLS
(oN-Line System) in 1962
NLS demonstrated in 1968
Many academic research projects
and powerfull systems since then

World Wide Web (WWW)
Invented at CERN Tim Berners-Lee and Robert
Cailliau
started in 1989
first release in 1991
Not implementing many of
the features developed by the
hypertext community bidirectional links
transclusion
external links

Web 2.0
User becomes an author
and shares information
tagging
Wikis
social networking
mashups
..
Not a new technology!
Why did some of these
things not happen earlier?
limitations of original WWW?
Beat Signer - Department of Computer Science - [email protected] 9February 9, 2010
Semantic Web (Web 3.0)
Add explicit semantics
to Web resources
Machine-interpretable
Web
Use of ontologies
Potential reasoning over
Web resources[http://en.wikipedia.org/wiki/File:W3c-semantic-web-layers.svg]

Cloud Computing
The cloud hides technological details from the user accessed over the Internet (e.g. via web browser)
customer no longer owns the physical infrastructure
utility computing vs subscription-based services
Microsoft
Yahoo
Amazon
Cloud
Beat Signer - Department of Computer Science - [email protected] 11February 9, 2010
Cross-media Information Systems
Information moves from
digital to physical space
and vice versa
e.g. paper-digital integration
Multimodal interaction
How should information
be stored and accessed?
use of web technologies?
desktop metaphor still
appropriate?

Web Information Systems
Use the Web to access information stored in an
information system
Use Web technologies to organise information stored in
an information system
Use the Web as an information system
In the seminar we investigate new trends, concepts and
technologies for web information systems

Some Tips for the Presentation
Talk to the audience and not to your laptop screen do not read your talk
Make use of available resources and tools (in addition to
PowerPoint) if appropriate overhead projector
black board
paper handouts
laser pointer/highlighter
...
A quick demo, movie or application screenshot can often
help to clarify an approach
Beat Signer - Department of Computer Science - [email protected] 22February 9, 2010
Some Tips for the Presentation ...
Content do no overload your slides with entire sentences
- the audience can not read overloaded slides and at the same time listen to you
the slides should support your talk rather than being a script that you read from the screen
careful use of graphical features
- a fancy slide background might reduce the readability
- too many colours and different fonts can be distractive
- no "misuse" of animations or sounds
make sure that you do not have too much content for the 30 mins
- rehearsal
Beat Signer - Department of Computer Science - [email protected] 23February 9, 2010
Some Tips for the Presentation ...
Presentation style the audience will be more attentive if they see that you are
motivated to give the presentation
think about your body language
Preparation a good preparation gives you more confidence and freedom
during your presentation
