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

"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.”

Software Perspective The internet is the computer, the browser - the new OS, the new

ASP, etc. Universal & pervasive computation

Business Forecasts: "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 Mass personalization Increased personalization of

Products Information and knowledge Medicine and health

Intelligent living spaces and appliances

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

3 million pages added per day plus other media doubling every year

Much is only available through a limited query interface Use the computer’s language; not ours NLP is still not mature

Search engines - not everything is indexed or up-to-date

Limited personalization; bots are still young, but maturing

The World Wide Wait Much is still not on the web (decreasing as I speak)

Goals for IST 220 A theory and practice course Learn by doing (hands-on experience) Emphasize learning skills as well as

knowledge of the subject Cover both technical/managerial aspects Emphasize computing applications Focus on emerging information

technologies
