tips ~ searching the Internet |
Introduction
Looking for data on the Internet can be a hit and miss affair. You perform
a search and you have thousands of results to investigate. Wouldn't you like
to achieve better and more accurate results with your search?
Making
use of Google's Advanced Search page
The
vast majority of Internet users simply use
Google to look for that information on the
Internet. They type in "google" in their
favourite web browser's address field and
this is the page that they view.
|
|
This
is a good start. You could do much better,
however, if you clicked on the "Advanced
Search"
link
on the right hand side of the search field.
Once the page downloads this is what you will
see.
|
|
If
you look closely at the options you will see
you can refine your search by specifying phrases
and even excluding terms from a search.
For
example if you commenced a search simply
using the words "ancient" and "Athens" you
would obtain results with pages that:
-
include
the words "ancient" and "athens"
-
include the word "ancient" and not "Athens"
-
imclude the word "Athens" and not "ancient"
-
include the phrase "ancient Athens"
Not all of the results would be suitable.
However
if you type the phrase "ancient Athens" in
the second search field illustrated above,
"Find results with the exact
phrase", you will
obtain results that feature web pages with
that exact phrase.
You
may like to refine the search even further
by typing in the word "Georgia" in the fourth
search field illustrated above, "Find
results without the words".
You will obtain results that do not
feature many web pages with mention of the
city of Athens, Georgia in the United States.

Additional
refinements available on the Advanced Search
page …
If
you look closely at the screen shot above
you will see that there are additional
refinements that can assist you to narrow
your search results to a better set of
worthwhile or meaningful web sites.
-
Language:
This will assist students of a second
language. You may be looking for specific
cultural items
-
File
format: You may be looking for a ‘pdf’ or
powerpoint file that you had discovered
earlier
-
Date:
You wish to obtain a recent article on
the topic.
-
Occurrences:
You may only be interested in pages that
refer to your
topic or search
interest within
the page content. Sometimes
your keyword(s) are contained
in the ‘tags’ or
html of the web page and
not within the visible content
-
Domain:
Why search the entire
Internet when you can
simply search within
a single domain or
web site. Example: http://www.nationalgeographic.com/
or http://www.boardofstudies.nsw.edu.au/
-
Usage
Rights: Look for materials that are free
to use and share
-
Safe
Search: Filter your results by selecting
the "Filter using SafeSearch" button

Search
engines other than Google ~ Kartoo and Vivisimo
Have you tried 'Kartoo'
that presents your results as an interactive
concept
map or ''Vivisimo'
that clusters and organises your results
into
categories?
|
|
When you perform a serach using Kartoo you
can choose between 'UK pages' or the 'world
wide web'. Sometimes the choice is 'English
pages'.
Kartoo provides an interesting way in which
to
search for information on the Internet.
It
displays
the results of your search in two formats.
One representation is a structured concept
map of the results that categorises results
according to relevance and significance.
An example is shown below.
|
|
Kartoo also represents
the data as a set of categorised links to
the left of the interactive map. See the
example below. Visually minded learners
may prefer
to use this search engine.
|
|
Another search engine worthy of your exploration
is Vivisimo. This search engine clusters your
search results as a set of useful categories.
|
|
As you can see with the results below a
search on 'Ancient Athens' brings up
a set
of categorised results. That could
be very useful both for the teacher
and the student.

Domains
Keep
in mind the significance of the various domain
name descriptors:
-
.edu:
Educational web site (or .ac in the
UK and Japan)
-
.org:
Non profit organization
-
.com:
Profit making organisiation (or .co in
the UK and Japan)
-
.net:
Concerned with the Internet
Which
ones do you think will contain the most
credible information for teachers
and students? You can specify that only
pages with specific domains are the source
of your results in a Google advanced
search. See the screen shot below.
… and
there are others of course (tv, biz, id,
etc)
In
the example illustrated below a phrase
search on the term 'ancient Athens' is
restricted to sites that include the
descriptor '.edu' in the domain name.

Meta-search engines
A
meta serach sends your search to multiple
search engines simulatenously. It collects
the results and then displays them for your
further investigation.
Visit
this web site at the University of California
in Berkeley for an excellent description
and review of meta-search engines.

Searching
for images
A
number of school district and regions have
filtered Google images so that students are
not unwittingly bombarded with inappropriate
images. It is not possible to access Google
images in some schools as a result.
If
you do use Google to search for images on
the Internet then you should try Google's Advanced
Image search. You
can refeine your search with specific terms
as with a word search. You can also specify
various characteristics for the images including:
-
File size: small, medium or large
-
Filetypes: jpg, gif or png
-
Coloration: black & white, grayscale
or full colour
In addition to these specifications
you can also specify the domain for your search
as well as providing three different levels
of filtering:
See
the screen shot below.

Alternative image search sites on the Internet
When searching for images it is also possible
to use dedicated image
hosting
services
such as ‘Photobucket’, ‘Web Shots’ or ‘Flickr’.
Each of these sites have usage policies that ensure
that
inappropriate images are not placed online or, in the event that they are,
members of the public can report the abuse and they will be removed.
-
Web
Shots: http://www.webshots.com/homepage.html
-
Flickr:
http://www.flickr.com/
-
You
can search these galleries for images of
countries, towns, cities and places
that may be useful for your project. Recently
I located a large selection of
excellent high resolution photographs of Pompeii following a search in Photobucket.
Wikipedia
What is Wikipedia?
This is an online encyclopaedia that is constantly being updated by
experts and enthusiasts that are interested in the topics
displayed in its pages. It is also an good source of
information
for current news events.
It should be considered as a method for quickly obtaining information
on a topic and not as a 100% credible source of information. Quite
often the Internet links at the foot of a Wikipedia article can be
very useful.
Wikipedia pages
can be a source of misinformation as well since anyone can
edit a page in Wikipedia. It can include pages with biased views. News
reports
have revealed how politicians, celebrities and other individuals have
created and/or modified entries regarding themselves and others in
a self serving and subjective manner.
