USING THE INTERNET

The usage of the Internet requires :

1. Preparing a set of keywords

2. Choosing a search tool

3. Evaluating sites and information

1. Preparing a set of keywords

• Analyse your topic to find keywords

– The major difference between a search in a catalogue and a search on the Internet is that Internet requests are made with natural language keywords

2. Choosing a search tool

On the Internet, there are different tools to find information :

• General tools, that allow a broad search, such as Search engines (e.g. Google, Yahoo)

• Specialised tools, that allow a narrower search:– Specialised search engines (e.g. Google

Scholar)– Subject gateways

Search Engine

• Characteristics of a search engine:– You make requests by typing words and/or

keywords for precise searches– The engine returns answers when you make

the request : dynamic search and dynamic answers

Function of search engine

• How does a search engine function ?– A web crawler visits the world wide web

at regular times

– It captures all the sites it finds

– The pages of these sites are indexed (more than 20 billion pages for Google)

How does a search engine gather and present return results?

A few questions

• The example of GOOGLE : Is the capture of a site linked to the payment of a fee ? No

• Are sponsored links differentiated from other links ? Yes

• In what order do results appear on the screen ? They appear by order of popularity …

• Is the position of a link among return results linked to the payment of a fee ? No, but there can be commercial links between search engines and companies. Results can be biased.

Google : Basic Search

Google functionalities : Basic Search

• Type a keyword or several keywords using the Boolean Strategy

• Remember that Google does not take into account capital/small letters, singular/plural, accents

• To enter an expression put it in quotes e.g. « expression »

Google : Advanced Search

Limiters

Google functionalities : Advanced Search and functions

• Advanced search :

– Keywords to type in fields

– Limiters : language, file formats (pdf, html …), domains (.org, .edu,com …)

• Specific functions :

– Similar pages

– Cached pages

More options to display the results of your search :

- Narrowing search to sites indexed at a particular time or a particular range of dates

- Showing fewer or more commercial links- Choosing your sources : forums, blogs, videos,

reviews- Displaying related searches in different modes (by

year, as a diagram …)- Something different: suggestions of expressions or

words related to the words you typed

.

3. Evaluating sites and information

Criteria to apply to references returned by search engines : are they relevant ?

1. Authority / Reliability• Are the editor and contributors of the site qualified ?• First checks can be made by watching the URL and

the domain :– Is there the name of an institution (ministry, University,

reasearch organisation …), of a research center, of any producer of official information within ? In this case, the information is reliable

• The domain gives indications about the origin of the site :.com, .edu, .org, .ac.in …

• Always look for the names and qualifications of the contributors

2. Currency

• Is the information dated ? Is it updated ?

• Find when the page which contains the information has last been updated

3. Relevance to your topic

• Does it give you the information you are looking for ?
