Background

History

Definition of Net

The Internet is the publicly accessible worldwide system of interconnected computer networks that transmit data by packet switching using a standardized Internet Protocol (IP).

It is made up of thousands of smaller commercial, academic, domestic and government networks. It carries various information and services, such as electronic mail, online chat, and the interlinked web pages and other

documents of the World Wide Web.

WWW domination

How big is the web?

• 56 billion static web pages are publicly-available on the World Wide Web.

• Another estimated 6 billion static pages are available within private intranet sites

• 200+ billion database-driven pages are available as dynamic database reports ("invisible web" pages)

• Google.com indexes 9.75 billion web pages.

Deep Web

• The invisible web,, a vast repository of information that search engines don't have access to, such as databases

• Private networks, called intranets, that are not actually hooked up to the Web

• Forms, like ColdFusion or CGI • Password-protected sites, like a university

library • Sites that intentionally, for various reasons,

keep their information from being indexed by search engine spiders

Today

• 200 Billion• Only 50 Billion is static web• Geogle only indexed 20%• Daily Web Space increase

100,000 websites

Information Evaluation

Web Evaluation Techniques

Before you click to view the page...• Look at the URL - personal page or site ?

~ or % or users or members

• Domain name appropriate for the content ? edu, com, org, net, gov, ca.us, uk, etc.

• Published by an entity that makes sense ? • News from its source?

www.nytimes.com• Advice from valid agency?

www.nih.gov/www.nlm.nih.gov/www.nimh.nih.gov/

Web Evaluation Techniques Scan the perimeter of the page• Can you tell who wrote it ?

• name of page author• organization, institution, agency you recognize• e-mail contact by itself not enough

• Credentials for the subject matter ?– Look for links to:

“About us” “Philosophy” “Background” “Biography”

• Is it recent or current enough ?• Look for “last updated” date - usually at bottom

• If no links or other clues...• truncate back the URL

Web Evaluation Techniques

Indicators of quality

• Sources documented• links, footnotes, etc.

– As detailed as you expect in print publications ?

• do the links work ?

• Information retyped or forged• why not a link to published version instead ?

• Links to other resources• biased, slanted ?

Web Evaluation Techniques

– Type or paste the URL into the basic search box

– Traffic for top 100,000 sites

• See what links are in Google’s Similar

pages

• Look up the page author in Google

Web Evaluation Techniques

STEP BACK & ASK: Does it all add up ?• Why was the page put on the Web ?

• inform with facts and data? • explain, persuade? • sell, entice? • share, disclose?• as a parody or satire?

• Is it appropriate for your purpose?

Try evaluating some sites...

1. Search a controversial topic in Google:– "nuclear armageddon"– prions danger– “stem cells” abortion
