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
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
to go to the information, but at times you will see hypertext
links (underlined text) too.
b The
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
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.
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).
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)
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:
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.
