INTERNET AS A KNOWLEDGE REPOSITORY

1. Internet as a
Knowledge Repository

2. • A Knowledge repository is something which captures,
packs & stores relevant knowledge.
• In other words, it means a place to store knowledge and
retrieve knowledge. Hence internet is truly a knowledge
repository.
• Intranets & Internets offer new ways to manage &
communicate data, information & Knowledge.
• Knowledge repository formation involves
1. Identifing knowledge resources
2. Capturing identified knowledge
3. Organizing captured knowledge.
4. Transferring the captured knowledge.
Internet as a Knowledge Repository

3. • In this internet world, we can search any kind of
information.
• Typing of a keyword in the search engine provides a
lot of information about it.
• Internet is recognized as a rich source of information.
• Development of ICT has yielded an unlimited variety
of databases & multimedia platform.
• It supply multifarious needs including knowledge,
edutainment, entertainment, leisure activities,
consumer facilities, interpersonal interaction, etc.

4. • With development of ICT, there is an ever-increasing no.
of New users who yearly join & many millions who are
already familiar with on line www activity.
• Many of the online users are students who utilize the www
as a portal to the world of knowledge both formal &
informal.
• The educational system understands unlimited learning
possibilities presented by ICT and integrates the use of
ICT in learning in general & in online learning in particular.

5. Academic Search
Techniques

6. Search Engine
A search engine is a tool or a program
designed to search for information on the
www on the basis of specified keywords and
returns a list of the documents where the
keywords were found.
The search results are usually presented
in a list and are commonly called hits.
The information may consist of
WebPages, images, information and other
types of files.

7. Quotation Marks and Truncation
In library catalogs and article
databases, the two most helpful
advanced search techniques are:
1) Quotation Marks
2)Truncation or Wild Card

8. Quotation Marks
Quotation marks are used around phrases.
By using quotations marks, you are telling
the computer to only bring back pages with
the terms you typed in the exact order you
typed them.
Example:
“health care reform”
instead of
health AND care AND reform

9. For example, if you are interested in finding
information on social networking, it is best to
search for “social networking” in quotation
marks. Otherwise, the computer might
search for social AND networking and find
many more irrelevant results.

10. Truncation
Truncation means to chop
off. When you truncate you
chop off the end of the
word, so the computer can
search for multiple endings.
For example, your research
question includes the
keyword education. You can
truncate education, so that
the computer will find all of
the word ending variations.
Educat* will find:
Education
Educate
Educated
Educating

11. Be careful where you place the truncation
symbol. Educate* will not find education or
educating, although it will find educate and
educated.
Truncation will not find synonyms (i.e. scien*
will not find the words botany, biology, or
astronomy), although it may bring up articles
on those topics IF they include the words
science, scientific, or scientist.

BOOLEAN
SEARCHING
How it can help you do effective
database and Internet searching

13. What is Boolean searching?
• It is based on a method of logic
developed by George Boole, a 19th
century English mathematician.
• Most online databases and Internet
search engines support Boolean
searches.
• It allows you to do effective
searches by cutting out many
unrelated documents.

14. Basic Boolean Operators:
• AND
• OR
• NOT

15. AND
• Using AND narrows your search.
• It retrieves documents that contain
both of the search terms or
keywords that you specify.
• The more terms you connect with
AND, the fewer search results you
will find.

16. Example Using AND:
• Poverty AND
Crime
• Documents are
retrieved
containing both
search terms.
• Blue shaded area
represents search
results.

17. OR
• Using OR broadens your search.
• It retrieves documents that contain
either of the search terms or
keywords that you specify, but not
necessarily both.
• The more terms you connect with OR,
the more search results you will find.
(Remember: OR gives you more!)
• Use it to search for similar terms.

18. Tara Guthrie, 2010
Example Using OR:
• College OR
University
• Documents are
retrieved containing
either search term.
• Gold shaded area
represents search
results.

19. NOT
• Using NOT narrows your search.
• It retrieves documents that do not
contain a search term in your search.
• Use NOT to exclude a term from your
search and to find fewer results.

20. Example Using NOT:
• Cats NOT Dogs
• Documents are
retrieved containing
only information on
cats, and nothing on
dogs.
• Purple shaded area
represents search
results.

Advanced Boolean
Search Techniques
• “Quotation
Marks”
• (Parentheses)

22. “Quotation Marks”
• Using quotation marks narrows your
search.
• It requires words to be searched as
a phrase in the exact order that you
type them within the quotation
marks.
• Helpful for searching multiple-word
terms, places, or a person’s
name.

23. Examples Using “ ”
• “global warming”
• “New York City”
• “Sachin Tendulkar”
• Note: Using “quotation marks” will
give you different search results
than if you use the AND operator
between each word without quotes.

24. (Parentheses)
• (Parentheses) allow you to combine
any of the Boolean operators
together in combination.
• Use NOT and OR together to limit
your search.
• Use AND and OR together to expand
your search.
• Using ( ) allows you to combine two
possible searches into one,
and it saves you time.

25. Example using ( )
• “alternative energy” NOT (wind OR
solar)
• Using this search string would allow
you to find documents about
alternative energy, but not wind or
solar methods – it would only give you
other methods.
• Your search is narrowed by using NOT,
and you exclude more by using OR.
• How could this be divided into 2 searches?

26. How do I know which
Boolean Operators to use?
• AND
• OR
• NOT
• “ ”
• ( )

27. Sample Question #1
• I want to find information about
cloning humans.
• You may want to try a couple of search
strings for more varied results.
• Possible searches:
– cloning AND human
– “human cloning”

28. Sample Question #2
• I want to find information about
either Abishek Bachan or his wife,
Aiswarya Rai.
• Suggested search:
– “Abishek Bachan” OR “Aiswarya Rai”

29. Tara Guthrie, 2010
Sample Question #3
• I want to find information about
mummies, but not mummies in
Egypt.
• Suggested search:
– mummies NOT Egypt

30. Sample Question #4
• I want to find information about
behavior in cats.
• Consider: is there more than one
term used for a cat?
• Possible search:
– behavior AND (cats OR felines)

31. Sample Question #5
• I want information on designing web
sites, but not on specific web design
software programs.
• Consider: which software programs help
you create web sites?
• Possible searches:
– “web site design” NOT (Dreamweaver OR
“Front Page”)
– “web site design” NOT software

32. Tara Guthrie, 2010
Boolean Search Tips
• If you find too many search results,
you may need to narrow your search.
Revise your search by adding
additional terms using AND, or
excluding a term using NOT.
• If you do not find enough search
results, you may need to expand your
search. Try using synonyms for your
search term using OR.
