Information availability

  • Search engines account

for roughly 10% of content available on the Internet

  • What is the other 90%

that we cannot find by “Googling” for information?

– Web content that cannot be indexed

Search Engines 10% Deep Web 90%

Internet

slide-6
SLIDE 6

Indexed information (searchable)

  • Search engines index the Web

(typically by following links with crawlers also known as spiders)

  • Spiders follow links on web

pages to other pages to determine what exists and its importance

  • The more links to a page

typically indicates how important it is and helps with its search engine ranking

slide-7
SLIDE 7

What is not indexed?

  • Library catalogs
  • Bank account information
  • Store account information
  • Basically any Web site that is

password protected

  • Other sites choose to be
  • mitted from search results
  • Few “darknet” services such

as Tor (anonymous network)

How do we find information?

Thought question

  • How do we search for:

Boolean searching strategies

  • AND: result must include terms combined by the

AND

  • OR: result must include any terms separated by

an OR

  • NOT: result excludes specific terms after the NOT
  • (parenthesis): perform these tasks before others
  • “Quotes”: result must include an exact character

string

Google searching strategies

  • Conversions/calculations: converting variables
  • r calculating values
  • Regions: searching by region
  • Last update: searching based on time
  • Site: searching within a specific site
slide-32
SLIDE 32

Conversions/calculations

  • 5+10-8*10
slide-33
SLIDE 33

Conversions/calculations

  • 1600 meters in miles
slide-34
SLIDE 34

Conversions/calculations

  • 88 Fahrenheit in Celsius (F in C)
slide-35
SLIDE 35

Region

  • Search for information from a specific location
  • Acquire information from a region’s

perspective

– Write a paper on the Japan Tsunami in 2011 from the people’s perspective in Japan – Pair with Google translate to give you a good idea

  • f what the perspective was at the time

Last update

  • Good for current information that changes

quickly

  • There were incorrect reports of Gabrielle

Giffords’ shooting, where news outlets reported that she died in a shooting

– Based on the time of the update, you may get one reporting her death and another reporting that she was shot and in critical condition

slide-39
SLIDE 39

Last update

slide-40
SLIDE 40

Site searching

  • Search for information within a site
  • Good for locating information that you know

is in a specific site

– Example: searching for the final exam schedule within www.hawaii.edu – Search terms: site:www.hawaii.edu manoa final exam schedule

slide-41
SLIDE 41

Site searching

slide-42
SLIDE 42

Think about it

  • When would you use the following search

strategies in engines:

– Conversions/calculations – Region – Last update – Site searching

  • There are a lot more search refinement tools. For

more, check the Google Advanced search page (settings > Advanced search in any Google search)

  • Key is knowing what options are available and

how you may put them together

slide-43
SLIDE 43

Scholarly sources

  • Google Scholar

– Similar to Google search (scholar.google.com)

  • UHM Library databases
slide-44
SLIDE 44

Library databases

  • Hosting company (EBSCOHost)
  • Database (Academic Search Complete)
slide-45
SLIDE 45

Library database search strategies

  • Boolean
  • Field limiters

– Text (TX) – Author (AU) – Title (TI) – Subject heading (SU)

  • Reading a search result

Thought question

  • How would you search for information for a

report within your major?

  • What types of subject headings (SU) are

typical for your area?

slide-52
SLIDE 52

Search reliability

  • Scholarly sources: typical for school papers
  • Google Scholar

– Quick and mirrors Google’s search engine – May have inaccurate results

  • Library databases

– Limited to content in the database – Accurate results

slide-53
SLIDE 53
