Example asthma OR exercise yields pages that
include either word e.g., aerobic exercise and
atopic asthma
27
Boolean AND
A
B
AB
Example asthma AND exercise yields pages that
include both words
28
Boolean NOT

The Web as an Information Source
31
The Problem
Knowledge
Information
The Web is the ultimate expression of too much
data and not enough information David Seuss,
CEO, Northern Light
Data
32
Finding Your Way Around
  • Random surfing
  • Link Pages
  • Directories
  • Search engines
  • Metasearch tools

UC Berkeley Tutorial Finding Information on the
Internet
33
Random Surfing
  • No Road Maps
  • Low Hit Rate
  • Time-Consuming
  • Easy to Get Off Track
  • ButFun

34
Link Pages (PT Examples)
  • Andrews University
  • Cal State Long Beach
  • Univ Kansas Medical Center
  • PTNetwork.com

35
Internet Directories
  • Provide categorized lists of Web sites,
    constructed by humans (professional and/or
    volunteer editors)
  • Tend to be selective rather than all-inclusive
    (most aim for quality over quantity)
  • Usually include searchable database containing
    descriptions of the directorys Web sites
  • Require some knowledge of subject matter
  • Some categories can quickly become outdated

36
Internet Directories
  • General Directories, e.g.Yahoo!
  • Medical Directories (Examples)
  • Medscout
  • Galaxy Medical List
  • Achoo
  • MedWeb
  • Hardin MD

37
Search Engines
  • A computer-generated index of all the
    infor-mation found on all searched Web pages
  • Aims to include all Web pages that contain the
    information, but without assessing quality
  • Takes you to the exact page on which the words
    you are looking for appear
  • Regularly updated by automated processes

38
Top 7 Search Engines (By Coverage)
  • Google
  • WebTop
  • Alta Vista
  • Fast (All theWeb)
  • Northern Light
  • Excite
  • Inktomi (HotBot, MSN, Snap)
  • Go (Infoseek)

Improving Search Results
  • Boolean Operators
  • AND
  • OR
  • NOT
  • Search Engine Math
  • Proximity
  • Near
  • With
  • Wildcards

41
Search Engine Math
42
Proximity Searching
Asthma NEAR exercise
43
Wildcard (Truncation) Searching
Asth substitutes for any characters
Yields asthma, asthmatic, asthmatics,
asthmaticus, but also asthenia
44
Other Search Engine Tricks
  • Search by domain (e.g., edu, gov)
  • Search by URL (e.g, umdnj.edu)
  • Search by document title
  • Search by popularity/hits (DirectHit)

Metasearch Tools
  • Metasearch tools search the search engines
  • Best tools rank findings eliminate dups
  • Best results with customization
  • No medical-specific metaseach tool
