Evolution
of communication and ILS fields
No new information means no
communication
Shannon foundation/influence
How to measure noise?
Does indexing presuppose meaning in the message or the
receiver?
What does redundancy mean in language? E.g., 50%
redundancy
If meaning is constructed by receiver, how does
sender insure intended message is delivered?
Various ‘what is this good for’
Information
senses:
Thing/object
(what we handle, transmit, store)
Process
(act of informing)
The
change in mental state (signal—data—information—knowledge—wisdom)
Signal (mass/energy)
Data (ordered
mass/energy)
Information (data in a
human)
Knowledge (formalized
information and skills—represented mentally and/or physically)
Wisdom (the experience
to know the differences)
Communication
senses:
Process involving:
Two or more (human)
participants (sender/receiver, creator/audience, etc.)
Sender (initiator,
creator, etc.) has intention
Receiver’s mental state
changes
Time ranges from 0+ to
infinite
May be unidirectional
Object
(e.g., document)
Interaction
senses:
Mutual (reciprocal) action (process)
Two or more objects
(often we are concerned with one being human)
Either may initiate, may
be unintentional/random
States of both objects
change
Time ranges from 0+ to
infinite (but most often concerned with small latencies)
Always bidirectional
(feedback required, typically multiple cycles)
What
might it mean to interact with information?
Does information change when we ‘interact’ with it?
How
does digital information affect the possibilities of interaction?
For
HII do we also include the inferences and uses made of information?
