This document provides an overview of the evolution of the internet and web technologies. It discusses early precursors to the internet like Vannevar Bush's memex. It outlines the key developments that led to the creation of the World Wide Web including HTTP and HTML. It then covers the rise of social media and user-generated content through technologies like email, chat, wikis, blogs, photos and video sharing sites. The document also discusses semantic web technologies and standards like RDF and how they add structure and meaning to web content that was previously only accessible to humans.

39. Scientific American,
May 2001:
“... a goal of the Web was that, if the interaction between person and
hypertext could be so intuitive that the machine-readable information
space gave an accurate representation of the state of people's thoughts,
interactions, and work patterns, then machine analysis could become a
very powerful management tool, seeing patterns in our work and facilitating
our working together through the typical problems which beset the
management of large organizations.”
40. What is the Problem?
Consider a typical web page:
Markup consists
of:
rendering
information
(e.g., font size
and colour)
Hyper-links to
related content
Semantic content
is accessible to
humans but not
(easily) to
computers…
