Internet as a Internet as a Knowledge Knowledge RepositoryRepository

• 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

• 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.

Internet as a Knowledge Repository

• 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.

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.

Quotation Marks and Truncation

In library catalogs and article databases, the two most helpful advanced search techniques are:1)Quotation Marks2)Truncation or Wild Card

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

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.

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:

EducationEducate EducatedEducating

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.

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.

Basic Boolean Operators:

•AND•OR•NOT

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.

Example Using AND:• Poverty AND

Crime• Documents are

retrieved containing both search terms.

• Blue shaded area represents search results.

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.

Tara Guthrie, 2010

Example Using OR:• College OR College OR

UniversityUniversity• Documents are

retrieved containing either search term.

• Gold shaded area represents search results.

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.

Example Using NOT:• Cats NOT Dogs• Documents are

retrieved containing only information on cats, and nothing on dogs.

• Purple shaded area represents search

results.

Tara Guthrie, 2010

Advanced Boolean Search Techniques

•“Quotation Marks”

•(Parentheses)

“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.

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.

(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.

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?

How do I know which Boolean Operators to

use?

•AND•OR •NOT •“ ”• ( )

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”

Sample Question #2

• I want to find information about either Abishek Bachan or his wife, Aiswarya Rai.

• Suggested search:– “Abishek Bachan” OR “Aiswarya

Rai”

Tara Guthrie, 2010

Sample Question #3

• I want to find information about mummies, but not mummies in Egypt.

• Suggested search:– mummies NOT Egypt

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)

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

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.
