A PEDIATRIC ENVIRONMENTAL HEALTH SPECIALTY UNIT (PEHSU)
OBJECTIVES
By the end of this session participants will be able to: Describe uses of the Internet Evaluate WWW documents using criteria
discussed in the session Understand some of the limitations of the WWW Use a portal, a search engine and other types of
search systems to maximize effective Web searching
THE WORLD WIDE WEB – THE INTERNET
The World Wide Web = The Internet
Essentially the same things
THE WORLD WIDE WEB
A doorway to the world
A rapid means of locating and retrieving information
A rapid means of communication
TYPES of WEB SEARCH TOOLS General search engines – type in a word or
phrase and retrieve information based on algorithm AltaVista [www.altavista.com], Google Be cognizant of paid advertising
Multiple search engines – retrieve information from multiple search engines simultaneously Metacrawler, Dogpile [www.dogpile.com]
Directories – select from categories LookSmart [www.looksmart.com]
TYPES of WEB SEARCH TOOLS
Portals – combination search engine, subject directory, e-mail, chat, etc. Yahoo [http://www.yahoo.com/]
Subject-specific search directories MedWeb http://www.medweb.emory.edu/MedWeb/
Site-specific search tools – search box in corner
Databases MEDLINE, TOXLINE
TYPES of WEB SEARCH TOOLS On-line encyclopedias – Be very cautious
Some No oversight on content Anyone can change content
Political reasons Advocacy reasons
For example – Wikipedia and similar Not appropriate tool for professional use
Others Have oversight, editors, peer-review, etc For example – Encyclopedia of the Earth
Evaluating Environmental Health Information & Avoiding Misinformation
EVALUATING RESOURCES
Rationale Anyone can publish anything on the Web Unlike traditional print resources, web resources
rarely have editors or fact-checkers Currently, no web standards exist to ensure
accuracy
EVALUATING RESOURCES
Authority Who is the author? What is the author’s affiliation? Can you contact the author?
Objectivity Is the purpose of the site clearly stated? Is sponsorship acknowledged? Is the information impartially presented?
EVALUATING RESOURCES
Accuracy Is it reliable and free from error? Is the source of information clearly stated?
Coverage Is it complete for the topic and audience?
Currency When was the information produced? Has it been updated recently?
EVALUATING RESOURCES
Example http://www.health-e-kids.org/ - About Us http://www.earthportal.org/ - About the Earth
Portal
EVALUATING RESOURCES
Using domain names .com - a commercial site .net - a commercial site .gov - a US government site .org - a non-profit site .edu - an academic site .mil - a US military site
EVALUATING RESOURCES
Using domain names – some new ones .biz - a commercial site .info – any type of site .int – international organization .aero – air transport industry site .coop - a co-op business site .museum – a museum site .name - a personals site .pro – a professional; e.g., MD, lawyer, etc
EVALUATING RESOURCES
Criteria for Assessing the Quality of Health Information on the Internet http://hitiweb.mitretek.org/docs/policy.html The Good, The Bad & The Ugly: or, Why It's a
Good Idea to Evaluate Web Sources http://lib.nmsu.edu/instruction/evalcrit.html
CONCERNS
Uncensored content Hoaxes, frauds, and “urban legends”
