Die

Internet: (31 March

Source: (31 March 2008) - The Future of
the
Internet--And
How to Stop It: (14 April
2008)This
extraordinary
book explains
the engine
that has
catapulted the
Internet from
backwater to
ubiquity?and
reveals that
it is
sputtering
precisely
because of its
runaway
success. With
the unwitting
help of its
users, the
generative
Internet is on
a path to a
lockdown,
ending its
cycle of
innovation?and
facilitating
unsettling new
kinds of
control. IPods
, iPhones,
Xboxes, and
TiVos
represent the
first wave of
Internet-cente
red products
that can?t be
easily
modified by
anyone except
their vendors
or selected
partners.
These
?tethered
appliances?
have already
been used in
remarkable but
little-known
ways: car GPS
systems have
been
reconfigured
at the demand
of law
enforcement to
eavesdrop on
the occupants
at all times,
and digital
video
recorders have
been ordered
to
self-destruct
thanks to a
lawsuit
against the
manufacturer
thousands of
miles away.
New Web 2.0
platforms like
Google
mash-ups and
Facebook are
rightly
touted?but
their
applications
can be
similarly
monitored and
eliminated
from a central
source. As
tethered
appliances and
applications
eclipse the
PC, the very
nature of the
Internet?its
?generativity,
? or
innovative
character?is
at risk. The
Internet?s
current
trajectory is
one of lost
opportunity.
Its salvation,
Zittrain
argues, lies
in the hands
of its
millions of
users. Drawing
on generative
technologies
like Wikipedia
that have so
far survived
their own
successes,
this book
shows how to
develop new
technologies
and social
structures
that allow
users to work
creatively and
collaborativel
y, participate
in solutions,
and become
true
?netizens.?

ussion in the
research
community and
among the
general public
regarding
content
indexing
(especially
subject
indexing) and
access to
digital
resources,
especially on
the Internet,
has
underutilized
research on a
variety of
factors that
are important
in the design
of such access
mechanisms.
Some of these
factors and
issues are
reviewed and
implications
drawn for
information
system design
in the era of
electronic
access.
Specifically
the following
are discussed:
Human factors:
Subject
searching vs.
indexing,
multiple terms
of access,
folk
classification
, basic-level
terms, and
folk access;
Database
factors:
Bradford's
Law,
vocabulary
scalability,

y 30:1 Rule;
Domain
factors: Role
of domain in
indexing.

Attention in
Collaborative
Tagging
Communities: (7 May
2007)Collabora
tive tagging
has recently
attracted the
attention of
both industry
and academia
due to the
popularity of
content-sharin
g systems such
as CiteULike,
del.icio.us,
and Flickr.
These systems
give users the
opportunity to
add data items
and to attach
their own
metadata (or
tags) to
stored data.
The result is
an effective
content
management
tool for
individual
users. Recent
studies,
however,
suggest that,
as tagging
communities
grow, the
added content
and the
metadata
become harder
to manage due
to an ease in
content
diversity.
Thus,
mechanisms
that cope with
increase of
diversity are
fundamental to
improve the
scalability
and usability
of
collaborative
tagging
systems. This
paper analyzes
whether usage
patterns can
be harnessed
to improve
navigability
in a growing
knowledge
space. To this
end, it
presents a
characterizati
on of two
collaborative
tagging
communities
that target
scientific
literature:
CiteULike and
Bibsonomy. We
explore three
main
directions:
First, we
analyze the
tagging
activity
distribution
across the
user
population.
Second, we
define new
metrics for
similarity in
user interest
and use these
metrics to
uncover the
structure of
the tagging
communities we
study. The
structure we
uncover
suggests a
clear
segmentation
of interests
into a large
number of
individuals
with unique
preferences
and a core set
of users with
interspersed
interests.
Finally, we
offer
preliminary
results that
demonstrate
that the
interest-based
structure of
the tagging
community can
be used to
facilitate
content usage
as communities
scale.

5921105 We use
sequential
large-scale
crawl data to
empirically
investigate
and validate
the dynamics
that underlie
the evolution
of the
structure of
the web. We
find that the
overall
structure of
the web is
defined by an
intricate
interplay
between
experience or
entitlement of
the pages (as
measured by
the number of
inbound
hyperlinks a
page already
has), inherent
talent or
fitness of the
pages (as
measured by
the likelihood
that someone
visiting the
page would
give a
hyperlink to
it), and the
continual high
rates of birth
and death of
pages on the
web. We find
that the web
is
conservative
in judging
talent and the
overall
fitness
distribution
is
exponential,
showing low
variability.
The small
variance in
talent,
however, is
enough to lead
to experience
distributions
with high
variance: The
preferential
attachment
mechanism
amplifies
these small
biases and
leads to
heavy-tailed
power-law (PL)
inbound degree
distributions
over all
pages, as well
as over pages
that are of
the same age.
The balancing
act between
experience and
talent on the
web allows
newly
introduced
pages with
novel and
interesting
content to
grow quickly
and surpass
older pages.
In this
regard, it is
much like what
we observe in
high-mobility
and
meritocratic
societies:
People with
entitlement
continue to
have access to
the best
resources, but
there is just
enough
screening for
fitness that
allows for
talented
winners to
emerge and
join the ranks
of the
leaders.
Finally, we
show that the
fitness
estimates have
potential
practical
applications
in ranking
query results.

45-53.One of
the main
challenges in
today's world
of vastly
distributed
sources of
information is
to re-combine
information
sources to
provide
uniform
access. We
propose a
distributed
data
management
system that
should provide
the "glue" for
combining data
sources. This
system
advocates
services as a
means to
access data.
New services
are defined on
demand and
their creation
is supported
by a
behaviorist
approach that
incorporates
new service
ideas provided
by the user.
Services can
be based on
data and/or on
the output of
existing
services. To
increase the
usability of
services in
the system we
utilize two
ontologies to
denote
relevant
metadata.
Service
ontology
structures
existing
services and
helps in
discovering
new ones.
Parameter
ontology
structures the
parameters
used in
services and
supports the
creation of
new services.
Our proposal
of a
services-based
data
management
system
exhibits
similarities
to the
newsgroup
approach in
that both
"systems" are
examples of
semantic
search engines
based on user
interaction.
By exploring
these
similarities
and by looking
at some
statistics of
newsgroup
user/posting
behavior, we
validate our
services-based
approach.

present study
was designed

experienced by
children with

methodology
was used to

story were
related to the
continuity of
central or
incidental
information.
Twenty-two 9-
to 11
-year-old boys
with ADHD and
36 of their
nonreferred
peers watched
a television
program and
responded to
auditory
probes
presented at
preselected
points during
continuous
sequences of
central or
incidental
information.
The reaction
times to the
probes for
nonreferred
boys showed
the expected
linear
increase in
cognitive
engagement
(i.e., the RTs
increased) as
central,
plot-relevant
sequences
continued. In
contrast, boys
with ADHD
showed the
expected
increase in
RTs relatively
late in the
central
sequences. The
results were
discussed in
terms of how
delays in
engaging with
central
information
may contribute
to the
academic
difficulties
experienced by
boys with
ADHD.
