"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 cumbers-
ome. 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 May Think'
(1945) is often seen as
the "origin" of hypertext
 Article introduces the Memex
 memory extender
 store and access information
 follow cross-references in the form
of associative trails between pieces
of information (microfilms)
 prototypical hypertext machine
 trail blazers are those who find delight in
the task of establishing useful trails

The Mother of All Demos (1968)
 Douglas Engelbart and his colleagues
at the Stanford Research Institute
developed the oNLine System (NLS) as
part of the Augment Project
 vision about the future of interactive computing
 NLS was demonstrated at the Fall
Joint Computer Conference in 1968
 showed first practical use of hypertext
 computer mouse
 remote collaboration (connected computers)
 raster-scan video monitors
 screen windows
 ...

NLS Demo

Hypertext (1965)
 Ted Nelson coined the term hypertext
 Nelson started Project Xanadu in 1960
 first hypertext project
 non-sequential writing
 referencing/embedding parts of a document
in another document (transclusion)
 transpointing windows
 bidirectional (bivisible) links
 version and rights management
 XanaduSpace 1.0 was released as part of Project
Xanadu in 2007
Ted Nelson

Digital Documents as a Paper Simulator?
Most people don't understand the logic of the
concept: "What You See Is What You Get" is based
on printing the document out ("get" means "get
WHEN YOU PRINT IT OUT"). And that means a
metaphysical shift: a document can only consist of
what can be printed! This re-froze the computer
document into a closed rectangular object which
cannot be penetrated by outside markings (curtailing
what you could do with paper). No marginal notes,
no sticky notes, no crossouts, no insertions, no
overlays, no highlighting - PAPER UNDER GLASS.

them (with A, B and C) according to your preferences
 Send an email with your choices (e.g. 6A, 8B, 14C) to
bsigner@vub.ac.be no later than February 15
 Each student will be assigned a paper that has to be
presented in the seminar and the final seminar schedule
will be made available by next week

Seminar Organisation
 Presentation should be 30 minutes long (not longer!)
 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 …
 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: 21.5.2012

 Each student will be
assigned as a reviewer
for two other papers
 hand in a review via the
Open Conference System
 deadline: at least a week
before the paper is presented
 Each student is finally assigned as a metareviewer for a
paper
 hand in a metareview via the Open Conference System
 based on the two reviews and the metareviewer's knowledge
 deadline: at least one day before the paper is presented
 prepare at least two questions to open the discussion round

 Final grade is based on
 presentation (70%)
 written report
 reviews and metareview
 active participation in the seminar
 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
 Attendance to all presentations is mandatory!
 Schedule will be made available on PointCarré
 first presentations: 12.3.2013

Some Tips for the Presentation
 Talk to the audience and not to your laptop screen
 do not read your talk from paper
 Make use of available resources and tools (in addition to
slideware) if appropriate
 overhead projector
 blackboard
 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
 put the presented research paper in the right context (topic)
 investigate additional resources
- possibly use additional information (not from the paper) in the introduction
- check the content that is referenced in the paper
 do no overload your slides with long sentences
- the audience cannot read overloaded slides and at the same time listen to you
 do not just summarise the paper
- selection of important parts might be necessary due to time constraints
 use graphical features carefully
- a fancy slide background might reduce the readability
- too many colours and different fonts can be distractive
- no "misuse" of animations or sounds

 Content
 the slides should support your talk rather than being a script that
you read from the screen
 make sure that you do not have too much content for the 30 mins
- rehearsal
 if you copy content from the paper (e.g. figures) make sure that
they are readable – otherwise redo them
 avoid "empty" slides like the classical "Questions?" slide at the
end of a presentation
- the last slide is likely to be shown during the entire Q&A session and should
therefore be used for your give away message (e.g. some conclusions)
 prepare some backup slides which might support you during the
Q&A session

 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
 practice, practice, practice, ...

Some Tips for the Audience
 Of course the first and most important thing is that you
listen to the interesting talks and learn some new things
 Other things you might observe during the presentation
 is the structure of the talk clear?
 what about the presenter's presentation style
 even if you should not comment about these things, you might
always ask yourself how you might have done things differently or
learn new things from good presentations
 Ask questions and give comments after the presentation
