Wat maakt computercommunicatie speciaal?
• onafhankelijk van tijd en plaats
• aanpasbaar aan verschillende behoeftes
• aanpasbaar voor diverse doelgroepen
• te hergebruiken voor andere doelen

E- versus face-to-face discussie
In your reply to David’s message at 21-Jan-2000 09:21:12 you said “that sucks”, but this is not what you said at 21-Jan-2000 09:20:30 to Pete.
“Hey, you just told Pete it was OK.”

Integrating Words and PicturesStudies show that designers must help readers:• search for the information they want in prose
and graphics,• make sense of it once they find it,• construct a coherent interpretation of the
prose and of the graphics,• generate connections between the words and
the pictures
![Page 18: Oriëntatie op CIW hoorcollege 6: Computercommunicatie](https://reader034.vdocuments.mx/reader034/viewer/2022051402/56815e72550346895dccf68c/html5/thumbnails/18.jpg)
‘Rhetoric’ for organising information
• something that is perceived as necessary for good document design: and particularly web design and online interaction...
• but how to systematise and teach it?
![Page 19: Oriëntatie op CIW hoorcollege 6: Computercommunicatie](https://reader034.vdocuments.mx/reader034/viewer/2022051402/56815e72550346895dccf68c/html5/thumbnails/19.jpg)
The GEM project:‘Genre and Multimodality’
(http://www.gem.stir.ac.uk)
Stages in Analysis• Content analysis: what ‘facts’ are being
communicated?• Layout analysis:
– what layout elements are there`?– what is their hierarchical structure?
• Rhetorical analysis: what is the RST structure?
• Does the layout support the rhetoric?
![Page 20: Oriëntatie op CIW hoorcollege 6: Computercommunicatie](https://reader034.vdocuments.mx/reader034/viewer/2022051402/56815e72550346895dccf68c/html5/thumbnails/20.jpg)
Relation between content, rhetorical organisation and layout
• examine the page layout
• examine the rhetorical structure of the information as presented
• look for interrelationships

Symbolic Authoringe.g., Drafter project http://www.itri.brighton.ac.uk/projects/drafter
Agile project http://www.itri.brighton/projects/agile
• Symbolic authoring allows a ‘writer’ to produce texts via a specification of the texts’ intended meaning rather than directly as text
• A text generation component then converts these specifications into natural texts
• Advantages: – the text generation component can produce a
variety of texts from the same information– e.g., variations in style and selected language– non-variation can be enforced, e.g., terminology

New Technologies and CMC
• New technologies (such as Natural Language Processing) are changing the role that the computer can take on when mediating information
• There are already significant applications where information presentation is largely taken over...
