Getting the full picture ! Using different sources to get information Asstt. Librarian SKUAST of Jammu
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 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 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 ?
