INLS 180 Day 12 Notes
February18, 2004
Reminders: Web structure assignments due March 1
Next Monday project commits
due
Main Points
Assessing user needs is
important and there are many methods for doing so
Structure plays a strong role
in communication
Message itself
Rapid digest
Flavors/intonations
Audience selection
Usage and retention
TV is no longer as
passive—more multitasking
Media manipulation is about
both money and control
Multiple info streams a trend
Even sophisticated
readers/viewers are influenced by seductive details and crafted messages
Many messages are partially
subliminal
Look at old tv/film and compare to today [a term project]
Questions
Are there new kinds of info
seeking behaviors emerging? E.g., channel surfers, multitaskers?
How can TV commercials become
more interactive?
How will technological
innovations change things? Be useful? How do IPs fit?
How many of us watch TV? [how many Americans watch TV?]
How is video interactive?
Entertainment
to art continuum?
Backlash
against overload? [info overload as disease agent]
What are our
saturation/overload levels?
What structure tags for
video? [see
MPEG-7]
What are implications for
Baby van Gogh and other media for very young children?
Why is email like a postcard?
What media messages actually
influence behavior? Are most powerful?
Does the media blast
eventually create a fear of silence?
What would Tufte say about text crawls on screens?
Do TV styles differ across
cultures? [see Lost in Translation]
2. Information seeking
(snowed out….will skip this discussion for now)
Needs/personal knowledge-ŕstrategiesŕtacticsŕmoves
Technical advances change
this human process
Written language shifts effort from real-time attention
and long-term memory accuracy to reflection on the fly/pausing within flow
Electronic communication continues to discretize
process and adds new ones
EC also adds new community possibilities
Augmentation of
the intellect:
more
stuff (new critical masses lead to economies of scale, or sustainable special
interests)
tools
that change strategies, tactics, moves (e.g., shift from finding to filtering)
communities
that enable SIGS and recommendations
Digital
libraries are memory augmenters
3. Discuss Bibliometrics and scholarly communication
Informetrics and Bibliometrics
queueing theory, circulation models, operations research
citation analysis, from individuals to groups to organizations; from doc to doc to doc to field to field to field
see http://www.cybergeography.org/atlas/info_maps.html for maps of comm patterns
Logical Assumptions (Griffith, Drott & Small)
1. X cited by Y is more likely to be related to Y than arbitrary A not cited
1. X cited by Y and A not cited by Y=>more likely that X was used in preparation of Y
2. Y and Z cite X=>more likely Y and Z are related than A and B citing no docs in common
Y cites X and Z=>X and Z more likely related to each other than to A not cited by Y (not co-cited with X and Y)
Problems of citation analysis
Multiple authors
Self-citations
Homographs (same name/different authors)
Synonyms (name variants)
Types of sources (books vs journals, some journals limit citations)
Implicit citations (discussed or implied but not cited)
Time fluctuations (year to year)
Field variations (e.g., humanities vs sciences)
Errors
See web of science from UNC Library page
See www.citeseer.com
Applications
Various literature studies
User studies
Historical studies
Communication patterns (e.g., how ideas spread)
IR (e.g., google, Clever today)
Collection development
Recommendation systems
4. Discuss
Smith paper
5. Scholarly
communication: discuss Kling & McKim paper
6. One-minute paper
What was the big point you learned in class today?
What is the main, unanswered question you leave class
with today?
