   The Internet

Surfing is not
searching.
“Computers download information—
• They do not teach you to think.
• Computer education imparts technical
  skills;
• It does not impart knowledge.”
•   John Rosemond
“Not all the information that exists in
the world is on the Internet--

Not all the information that is on the
Internet is accurate.”
Mrs. Kotsch
An hour on the Web may
not answer a question that
you could find within two
minutes of picking up a
reference book.
Getting Started Searching
• URL’s
• Searching techniques
• Search engines
URL’s
•   Uniform Resource Locator
•   The web “address” that connects you with a website
•   Goes in the address bar at the top of the screen
•   Gives you information about the website
Parts of a URL
    http://www.starwars.com/seminars.html

• http://--hypertext transfer protocol:
•    the language computers use to “talk” to one another
• www—world wide web:
•    the body of information connected by the cables and computers of the Internet
•    .starwars—domain name:
•    the structured, alphabetic-based, unique name for a computer on a network
•    .com—top        level domain:
•    gives an idea of where the document is stored
•    /seminars—file              name:
•    a folder within a website
•    .html—hypertext             markup language:
•    the computer language used to format documents
Top Level Domains
•   .edu—higher education
•   .k-12—elementary and secondary schools
•   .com—commercial
•   .gov—government agency
•   .mil—military
•   .org—general noncommercial organization
•   .net—computer network
Who Pays For The Internet?
•   Advertisers pay for Internet websites.
•   Popups and banners are trying to influence your spending habits.
•   The information on commercial sites--.com—may be presented in such
    a way as to encourage you to buy a particular product.
•   Be wary of URL’s with a ~ in the address—this indicates a personal
    homepage and does not guarnantee accuracy.
How Do You Find What You Need?
• Libraries and department stores are planned.
• No one is in charge of organizing the Internet.
• Well-prepared searches will eliminate useless hits and
  wasted time.
Before you search, you need to:
• Prepare
• Organize
• Combine
Prepare
• What do you need to know about your topic?
• Make a list of all the terms connected with your topic.
• Include names, organizations, and phrases.
Organize
•   Make a list of the words that are critical to your search.
•   Note terms that you don’t want to see appear.
•   Discard the rest.
For example…
If you are looking for information about life on the planet Mars, you
don’t want sites popping up about the Roman god of war.
Put that in your list of words you don’t want to see.

What other words might be connected with your topic that will send you to
useless sites?
Combine
Use Boolean operators to combine your most
  important terms.

•   Use AND to connect the terms you want to see.
•   Use NOT to exclude terms you don’t want.
•   Use OR to include similar terms.
•   Use quotation marks around names or phrases
•   Use lower case for all proper nouns, except for acronyms
For example…



    mars AND planet AND life NOT god
But what if…


you WERE looking for information about the Roman god of war?
The Greeks referred to him as “Ares”, so now your search will look
like this….
    mars OR ares AND “god of war”



Notice the quotation marks around the phrase “god of war”
What Do You Use To Search?
• Search engines
• Search directories
• Metasearchers
Search Engines
• Are like the index in the back of a book
• Let you search for specific words and topics
• Use robots known as spiders to search for
  information.
Examples:
•   Alta Vista
•   Excite
•   Hotbot
•   Infoseek
Search Directories--

•Are like the table of contents
in front of a book

•Let you search for concepts or subject
categories
• Go from general to specific.

•Sites are added by people.
Examples:
• Internet Public Library
Instead of looking through the
categories in a search directory, you
can put in your terms in their search
bar, but it will only look through the
sites that have been included within
that directory—not the entire web,
unless indicated.
Metasearchers--
• Sends your search terms to several other
  search engines at once.
• Gives an overview of a topic across the
  Internet.
Examples:
• Profusion
• Dogpile
• Metacrawler
Remember….
• Hits are returned and ranked according to--
•   How   many times terms appear on the page
•   How   often terms appear
•   How   close terms are to each other
•   How   near the top of the page the terms are found



• The best results will appear on the first page
  or two of hits
• No two search engines are alike. Try another
  search engine, or rephrase your terms if you
  don’t get good results.

       Evaluating Websites
         “Let the buyer beware”

Book publishers weed out inaccurate information.

No one checks the Internet for accuracy.
Before you start using the
      information--


  EVALUATE!
Who is the author?
• Is he an authority on the subject?
• Does she have an e-mail address?
Is the information accurate?
    • Can it be verified in an encyclopedia?
         • Is it relevant to your topic?
 • Does the author indicate where he found the
                    information?
Is the information prejudiced?
• Is it trying to persuade you to another point of view?
• Is it trying to persuade you to buy a product?
   Is the information current?
• When was the last time the website was updated?
• Are the links broken?

  without telling your parents.

  that you run across.
• Be careful what you post in a public forum.

               Remember:

You leave “electronic footprints” wherever you
               go on the web.
