Web Science
Social and engineering dimensions (New York Times at launch of Web Science Program at Univ. of Southampton and MIT in 2006)
Extends well beyond traditional Computer Science
The Web isn’t about what you can do with computers. It’s people and, yes, they are connected by computers. But computer science, as the study of what happens in a computer, doesn’t tell you about what happens on the Web.
–Tim Berners-LeeOne of the founder of WWW

Science (in a nutshell)
Existence Does X exist?
Description and Classification What is X like? What are its properties? How can it be categorized? How can we measure it? What are its components?
Descriptive Process How does X work? What is the process by which X
happens? What are the steps as X
evolves? How does X achieve its
purpose?
Descriptive-Comparative How does X differ from Y?
Relationship Are X and Y related? Do occurrences of X co-relate
with occurrences of Y?
Casuality Does X cause Y? Does X prevent Y? What causes X? What effect does X have on Y?
Design What is an effective way to
achieve X? How can we improve X?

Perspectives of “Science”
Physical/biological science perspectives Analytic disciplines that aim to find laws/processes that generate or explain
observed phenomena
Social science perspective Scholarly or scientific disciplines that deal with the study of human society
and of individual relationships in and to society
Computer science perspective Synthetic discipline that creates mechanisms (e.g., formalisms, algorithms,
etc.) in order to support particular desired behavior

Web Science
The Web is a new technical and social phenomenon and a growing organism
The Web needs to be studied and understood as an entity in its own right
Web Science is a new field of science that involves a multi-disciplinary study and inquiry for the understanding of the Web and its relationships to us

Why Web Science?
Dynamics and evolution The “deep (or dark) Web” Sampling, lack of complete enumeration Scale (e.g., What is the percentage of Web pages updated
daily?) Search (e.g., What percentage of Web pages are indexed by
search engines?) Web topology Artifacts of social interactions (blogs, etc.), Web sociology

What Could Scientific Theories for the Web Look Like?
Every page on the Web can be reached by following less than 10 links
The average number of words per search query is greater than 3
A wikipedia page on average contains 0.03 false facts The Web is a “scale-free” graph
