Welcome

• JCCC_at_DRDO

We see you as our partner in learning, not as an
audience to be lectured to from atop a platform

What are we going to talk about?

• Information seeking habits of potential users
• How do you help them?
• Foraging for information
• Dissuade them from using Backrub (Google)!
• - What form will the information assume? (Full
  text on line versus DDR)
• - Simple word / phrase search techniques
• - More complex search methods

3
The Deep Web

• Deep Web is a vast reservoir of Internet
  content that is 500 times larger than the known
  surface World Wide Web-scholarly information
  resides here
• Contains 7,500 terabytes of information compared
  to 19 terabytes of information in the surface web
• Has 550 billion individual documents compared to
  the 1 billion of the surface web

Simple tricks

• JCCC _at_ UGC INFONET is case insensitive
• Word phrase searching (specialized searching)
• e.g., polycarbonate fast fourier transform
• e.g., fractal and human genome project
• British American spelling variants
• e.g., orthopaedics orthopedics, fiber fibre,
  colour color
• Use abbreviations (in the topic)
• e.g., mhd or magnetohydrodynamics, emi or electro
  magnetic induction, LCD or liquid crystal
  display) etc.
• Do not use abbreviations for conducting a
  publisher search
• e.g., CUP (use cambridge university press), AIP
  (use american institute of physics) etc.
• Beware of spelling mistakes
• JCCC is unforgiving of spelling mistakes! Please
  check. You dont have a friendly genie prompting
  you did you mean was it like this can I
  help you?.
• Use Boolean connectors
• - e.g., AND (narrows), OR (broadens), NOT
  (excludes)

9
Simple tricks contd..

• Do not use apostrophes in your search
• -E.g., Eulers, Avogadros etc..
• Do not use umlauts (diacritics)-the umlaut
  consists of a pair of dots over a letter
• Umlauted vowels are a, o, u
• -E.g. Schrödinger's equation, Schön etc

10
Simple tricks (contd.) synonyms

• Use synonyms
• Flu common cold influenza
• Car automobile
• Road street avenue boulevard
• Germs bacteria virus
• Doctor physician
• Lawyer attorney
• Headache cephalagia migraine

11
Simple tricks (contd.) truncation

• forest will retrieveforest, forests, forested,
  forester, foresters, foresting, forestation, etc.
• tour will retrievetourism, touring, tourists,
  tours, tourmaline, tournament, etc.
• behavio will retrievebehaviour, behavior,
  behavioral, etc.

12
Truncation pitfalls

• Imagine you are looking for information about a
  symptom of a particular disease or disorder
• and decide to use truncation to retrieve
  variations of the word (e.g. symptoms,
  symptomatic, etc.)

13
Truncate at t

• Sympt
• Symptoms
• Symptomless
• Symptomatic
• Symptomatically
• Symptomatology

Heres what happens when we truncate at the t
14
Truncate at p

• Symptoms
• Symptomless
• Symptomatic
• Symptomatically
• Symptomatology
• Symposia
• Sympathetic
• Symphonic
• Symphony

Heres what happens when we truncate at the p
See how many more words you get- noise creeps in
15
Boolean AND (Narrows)
WHEN SHOULD I USE AN AND SEARCH?

• To narrow your search, tell the
• database that ALL search terms must
• be present in the resulting records.
• Example
• cloning AND humans AND ethics.
• The red triangle in the middle of
• the Venn diagram below represents the
• results for this search.
• It is a small set created by
• using AND, using all the
• 3 search terms

16
Boolean OR (Broadens)
WHEN SHOULD I USE AN OR SEARCH?

• To connect two or more
• similar concepts
• To broaden your search, telling
• the database that ANY of your
• terms can be present in
• the resulting records.
• All three circles represent
• the result set
• for this search. It is a big
• set because any of those
• words are valid using
• the OR operator.

17
Boolean NOT (Excludes)

• NOT is used to exclude words from your search
  results

For example, you might want to search for
articles on the pollution of beaches but exclude
items related to sewage
Your search strategy should be of the form
(pollution AND beaches) NOT sewage
18
Help me conduct a search

• A student comes to you with the following topic
• Analysis of heavy metals in sea water
• needs to find relevant articles
• How do you help him/her?
