Introduction



We are at the beginning of a revolution in information access
and creation. The internet has become the major facilitator.
 WEB - Distributed, large scale, online, rapidly growing,
searchable information resource accessible through a
browser; searching a billion page encyclopedia
This e-revolution is having a growing impact on business,
politics, science, environment, education, health, etc.
 More and more information is e-ized (digitized).
 Used by all aspects of society and the world: business,
consumers, scientists, educators, children, etc.
The web has radically changed what we expect when we
want information.
 It will continue to change and evolve!

Points of view

The '98 Asilomar Report on Database Research


Software Perspective



The internet is the computer, the browser - the new OS, the new ASP, etc.
Universal & pervasive computation
Business Forecasts:



"The majority of human information will be on the Web in ten years. It will
be an exabyte (1018) spread across the planet in many formats. Absent
new tools, finding and understanding answers to our questions will be
even harder than it is today.”
"By 2003, the Internet will become the predominant mechanism for
conducting business -- either to consumers or between businesses." Gartner Group
5% of the world's commerce, $3.2 trillion, will be Internet-based by 2003.
- Forrester Research
Popular Press:

"The Internet is the Gutenberg press on steroids. Gutenberg wasn't about
how many Bibles were printed, but the fact that you no longer had to
listen to the clerics. You could read it yourself and make your own
interpretations."- W. Wacker

Digitization Impact on the
Consumer or Individual
Rangaswamy, PSU, ’99


Mass personalization eBRC workshop, yesterday and today
Increased personalization of
Products
 Information and knowledge
 Medicine and health


Intelligent living spaces and appliances
17
Digitization Impact on Society




Digital knowledge is easily spread and available to
most
 enfranchising the disenfranchised
Intellectual property issues
 What is shared?
 What belongs to whom?
Privacy and security
 What is and isn’t protected
 What do we want protected
The e-zation of
 Government
 Institutions
 Companies
 Home

Digitization Impact on the Professor/Scholar
and the Modern University
Students, faculty, staff, etc. will have unprecedented access to
digital information




Available to most
 Portable digital portfolios
 Powerful computation/communication devices
Nearly all journals and manuscripts will be either online or in
PCs
 Scholarly publication will change.
 Not economically sustainable at current rate.
 researchindex.org – online access to over 250,000
papers in computer & information science
Research
 More data and computational power available
 Leveling the playing field
The student/faculty experience?
 What does the student want?
 What does the faculty want?

Why finding things on the web is not always easy

Abundance problem

Growing amount of information



Much is only available through a limited query
interface






3 million pages added per day plus other media
doubling every year
Use the computer’s language; not ours
NLP is still not mature
Search engines - not everything is indexed or up-todate
Limited personalization; bots are still young, but
maturing
The World Wide Wait
Much is still not on the web (decreasing as I speak)
