AskJeeves

( http://www.askjeeves.com) is a type of search engine that allows you to type in a question, using a normal English language sentence. Type in a simple sentence, asking a question and AskJeeves points you to several sites and often asks the question in other ways, pointing you to information sites. It is a highly recommended tool, especially for younger students and beginning searchers.

Tip: Jeeves is not a real person, so do not ask him where he stays. :-)

Let's follow an example search, asking the question "Who is Nelson Mandela?"

First you need to Log on to the Internet.

4.  Type in the Address: http://www.askjeeves.com (see 1 below)

5.  In the block indicated , type the question you want to ask (see 2 below) and click on ask.jpg (938 bytes)

AskJeeves will take a short while to return a result to you. The time you have to wait depends on the quality of your Internet connection at the time, but you should not have to wait more than a minute or so. Here is an example of the screen that AskJeeves presents to you in answering the question:

Note (referring to the lettering in the above image):

a   You click on ask.jpg (938 bytes) to go to the information, but at times you will see hypertext links (underlined text) too.

b   The downarrow.jpg (728 bytes) is used to find other categories of information relating to the same question, but would normally take you away from your immediate topic of search (Nelson Mandela, in this case).

c   AskJeeves offers you the answers it has given to similar questions asked by other people before you. You could explore these if they look valuable to you.

d   AskJeeves also rates the popularity of the information source. For example askrate.jpg (871 bytes) is a 5-star rating. However, this does not necessarily mean that the information will have that value for your specific needs.

e   If there is a longer list of sites that it offers, you should click on the More link.

f    AskJeeves also gives you links to information from related searches.

g   AskJeeves lastly searches some other popular search engines and gives you a summary of the results it found there. You could explore these as well.

Unsuccessful result?

If your initial question was not answered to your satisfaction, try to rephrase the question. AskJeeves has more than likely been put off track by a word that you used in the question. This word may have more than one meaning. Try to replace this word with a different one, or ask a slightly different question.

Yahoo 

( http://www.yahoo.com ) - Subject Directory / Information Index

Subject directory searches are probably best used for simple topics where the subject is obvious – a place, name of a person, name of a plant.

The following explanation should summarise Yahoo's strengths and weaknesses for you.

Yahoo has the advantage of

  • offering very specific searches through its subject directory.
  • You are therefore less likely to be presented with useless information.

However, it does have limitations in that it

  • only searches document titles.
  • Furthermore, if you are unable to categorise the information you seek, you will have trouble using Yahoo.

Yahoo offers you an information index i.e. it categorises information into 14 main subject categories as follows:

If you know something about the topic on which you are searching for information, it is possible to narrow down the field of search. That is, instead of searching the whole Internet, you can conduct a search in a specific subject area. Once you have narrowed the field of search to a specific subject, you then type in a specific search if it is still necessary (quite often it is not necessary since you will have discovered the information that you seek).

For example, let us look for information on Moss Animals. Note the information categories on the screen.

yahoo1.jpg (83847 bytes)

I think that the information lies in the Science category.  I therefore click on Science and I will be given further sub-categories of that information field (see below).

yahoo2.jpg (76162 bytes)

The numbers in brackets indicate the number of documents on that topic that Yahoo has available. The @ sign indicates that there are further sub-categories. Animals, Insects and Pets has an @ sign next to it, for instance.

I decide that Moss Animals falls under the category of Animals, Insects and Pets.  By clicking on Animals, Insects, and Pets I am able to access these categories as well (see below).

One of the categories now offered to me is in fact Moss Animals. I am fortunate. I have come to the level of documents. I notice that there are 5 documents (number in brackets) on Moss Animals. By clicking on Moss Animals I am able to access those documents (see below)

yahoo4.jpg (54304 bytes)

Click on the hypertext links to access the documents.

However, I could go one step further. If I was specifically looking for information about Moss Animals in Africa, I could now decide to search these 5 documents for references to Africa. I type in Africa in the Search box (circled) and choose to search in just this category (small circle). Then I click in the Search button and I find the following result:

yahoo5.jpg (32423 bytes)

Not one of the five documents about Moss Animals contains reference to Africa. My next step would be to use a different search engine that searches more widely than Yahoo. Remember, Yahoo only searches document titles. Alta Vista, a keyword search engine that searches entire document texts, finds 21 documents about Moss Animals in Africa.

Examples of other subject directories include:

LookSmart (http://www.looksmart.com)
Lycos (http://www.lycos.com)
Magellan (http://magellan.excite.com)
Open Directory (http://dmoz.org)
