Chug along with search engines

Here are ways of using Internet search engines to aid the information gathering process during research.

LINKS TO INFORMATION: Google is one of the most-commonly used search engines.  

"TO AVOID sifting through irrelevant information, a user needs to be sure of the kind of information he/she wants. He/She will also, in the process, have to learn how to rate information based on its relevance." It would be relevant to give brief indications about searching the Internet. When you have to retrieve a lot of information in the shortest possible time without missing any vital element, you should make use of strategies for effective search.

Most of us usually go to search engines such as the Google or Yahoo! and type a few keywords and open the sites that are displayed on the screen. This is not the most effective way for this exercise. Let us look into this in some detail.

Search engines

There are several search engines with their own special attributes. Each one may have its own focus. Some of the search devices other than the Google and the Yahoo! are alltheweb.com, ask.com, altavista.com, answers.com, books.google.com (very useful for finding books), factbites.com, infonetware.com, lycos.com, scholar.google.com (very useful for finding research papers), search.aol.com, searchedu.com, and wisenut.com. You may see their features by visiting them.

Remember that searching for a particular piece of information is like looking for a specific tree in a dense forest. If you take a wrong turn, you may never reach your target.

Carefully select the search terms, so as to narrow down the search in your desired area. Defining the topic as succinctly as possible also narrows down the search.

Keywords

You may list up to six or even eight keywords. The right combination of words is important. "Scientific temper'' for example gives something that cannot easily be brought in through "scientific'' or "temper" separately.

Use quotes ("... .") for restricting the search to sites containing what appears inside the quotes. Never hesitate to use the advanced search mode. If you can add a unique term, do so.

Most search engines are not sensitive to case; but sometimes capitalisation may help you. Try different search engines, if you find that one engine does not give useful results.

Use Boolean commands like AND and OR. If you type "elephant and ant and fly," only those documents that contain all the three words will be shown. If you type "elephant or ant or fly", documents that contain at least one of these will be shown on the screen. Articles (a, an, the), pronouns, or prepositions need not be included in key words.

Another style

There is another style of searching the Google. Go to directory.google.com.

You will find several headings such as Arts, Computers, Science, and Sports. On this page, if you click on science, you will find a long list showing different branches of science and related topics. Physics for example contains more than 5,000 sub-titles.

Among these, plasma has more than 300 divisions. Of these, nuclear fusion has more than 100 divisions. If you click on nuclear fusion, you go to cold fusion, with 24 divisions. From there you can go to any one of these sites.

You may narrow your search on any desired topic by clicking progressively in the directory site. Similar search facility is available at the site http://dir.yahoo.com. When you find a site very useful and think that you would want to visit it again, add it to the list of your favourites or bookmark it.

Record the searches

Whenever data is downloaded from a site, it is essential that you record the URL and the date of access. This information may have to be indicated in your bibliography. Remember that some sites may vanish later; still your record will remain valid.

If you want to find out the source of a certain well-known passage, you can find it using the Internet. Suppose you do not know the source of the famous quote "Cowards die many times before their deaths." You type this as keywords and imitate a search. You will immediately know that it is from Shakespeare's Julius Caesar (II, ii, 32-37).

Using e-mails

Yet another use of the Internet is the e-mail through which you can quickly and easily exchange ideas with other scholars or experts stationed elsewhere. When you have to discuss a point in detail with a person in a distant place, the facility of a chat room may be used.

Against all these merits of the Internet, there is a serious disadvantage with regard to the reliability of the contents. Articles in professional journals of quality get published only after they are scrutinised by experts in the field. Reputed publishers would bring out books only after they are read and recommended by experts or critics.

Matter that appears in the Internet cannot claim this kind of authority. Researchers should never swallow hook, line, and sinker whatever comes to them from the Net, without analysing it and confirming its acceptability. The scrutiny of material from the Internet has to be more severe.

You may check the reputation and credibility of the author as reflected in his other works. Also, you may crosscheck the information furnished by visiting other sources.

Positive results from "peer review" offer credibility to some extent. Such review is a process of assessment within a community of experts to regulate and control research activity.

This process ensures that the methodology is sound, and that interpretation of data may not lead to erroneous conclusions.
