Finding Your Way Around
A student wrote email last week ...
What should the student have done?
Prof. Snyder:You said the link to the FIT100 home page was on the [paper] syllabus, but only the Web page for the calendar was there:http://www.cs.washington.edu/education/courses/100/04wi/calendar/What’s the class homepage link?
Searching the WWW
Locating the right information on the WWW requires effort
Read Chapter 5
Looking In the Right Place
The WWW is not the first place to look Go directly to a site -- www.irs.gov
Go to right sight -- dictionary.cambridge.org Go to the library -- www.lib.washington.edu
OR www.mpcfaculty.net/library/ Go for the kind of information you want -- www.npr.org
Ask, “What site provides this information?”
Guessing a site’s URL is often very easy, making it a fast way to find information
Search Engines
No one controls what’s published on the WWW ... it is totally decentralized
To find out, search engines crawl WebTwo parts
Crawler visits Web pages building an index of the content
Query processor checks user requests against the index, reports on known pages
Only a fraction of the Web’s content is crawled
Google Advanced
Search for
Boolean Queries
Search Engine words are independent
Words don’t have to occur together To be explicit about occurrences use Boolean
queries and quotesLogical Operators: AND, OR, NOT
monet AND water AND lilies
“van gogh” OR gauguin
vermeer AND girl AND NOT pearl
Mona Lisa
Queries
Searching strategies …Limit by top level domains or formatFind terms most specific to topicLook elsewhere for key words, e.g. bioUse exact phrase only when universal If too many hits, requery“Search within results” using “-”Once found, ask if site is best source
Truth on the Web
Much Web information is wrong Using the Web effectively means
recognizing quality information Information from reliable organizations is usually
preferred -- check out ownership Look for accuracy, currency, … Follow links to verify that the content supports the
original page
Best: Locate independent verification
