Evaluating Information

As anyone can post information on the Web, its reliability is somewhat compromised. Here are some criteria to consider when evaluating an Internet resource.

Authority   |   Currency   |   Objectivity   |   Relevancy  |

 

Authority
Note the URL i.e. the address which begins with http. You can tell from its suffix where the site originates. Some of the most common suffixes are: 
           .edu for an educational institution .com for a commercial site
           .org for an organisation .gov for a government site
Sites from different countries sometimes do have their own suffixes to indicate the home countries as well: 
           .sg for Singapore sites .uk for British sites
           .cn for Chinese sites .jp for Japanese sites
No geographic suffix normally denotes an American website. ~ in the URL usually means that the page is a personal page put up by someone with no official affliation to the host site. 
Knowing the origin of the information will often give you an idea of the reliability of information you have found.

Sometimes if the credibility of the author cannot be established from the URL, look up the author of the information. If the author is with a reputable organisation or educational institution, this may add some credibility to the information. Many institutional or organisational Websites include statements about the type and source of information which is provided on their home pages, as well as the purpose of the organisation itself. If this information is not offered, be especially cautious with the information you found. It is important to distinguish between fact and opinion.

Currency
Currency is taking on a new meaning in the new electronic age. On the Internet, it is often unclear how old the information is. Copyright dates are not always provided and updates can be erratic. Look for the statement at the bottom of the page that indicates when the material was last updated. This gives you a clue as to its currency. On the other hand, the latest research and information is often published for the first time on the Web, long before it makes its way into print, so the Internet can be an excellent source of the very latest and most current information.

Objectivity
Is the purpose of the document or information clear? This will help you determine the validity of the information provided. Is it a scholarly research paper posted by an academic, or a piece of propaganda intended to present a specific point of view to persuade, or simply a personal collection of information put up by a single individual? Be sure to find out the intent of the author from the introductory and concluding paragraphs, the author's credentials and also the institution that hosts the website.

Relevancy

Relevancy is more important than ever in the electronic environment. There are millions of documents on the Web, so choose carefully, and don't just settle for the first thing you find or be distracted by interesting information that is not important. Make sure the information you are selecting is appropriate and relevant for your needs.
