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 ?
