"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.

...

Vannevar Bush


"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?


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

Google

Yahoo

Amazon

Cloud


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?

…

EdFest project


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

Seminar Topics ...

Topic assignment select 3 topics/papers from the presented list and mark them (with

A,B and C) according to your preferences

send an email with your choices (e.g. 1A, 7B, 4C) to [email protected] before February 16

each student will be assigned a paper to be presented in the seminar and the final seminar schedule will be made available


Seminar Organisation

Presentation should be 30 minutes long

Structure of your presentation introduction of topic and problem statement (5-10 mins)

proposed approach (15-20 mins)

review (5 mins)

- critical analysis

- at least two positive and two negative points about the paper

Send a draft of your presentation to your supervisor no

later than one week before the presentation and arrange

a meeting with your supervisor you will get feedback about the structure and content of your

presentation


Seminar Organisation …

Second assignment (buddy) read the paper in detail

prepare at least two questions

open the discussion round

Each student has to write a report about their presented

paper/topic same structure as presentation

not longer than 5 pages

send a draft to your supervisor to get some feedback

- arrange a meeting with your supervisor

deadline for final report: 18.5.2009


Seminar Organisation …

Final grade is based on presentation

written report

active participation

Everybody is expected to have a look at each week's

papers before the lecture after each presentation we should have enough time for questions

and a discussion about the topic and content of the paper

Schedule will be made available on PointCarré next lecture with first presentation: 16.3.2009


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


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


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
