Searching the Web

Be CyberSmart: Researching the Internet (11:27) featuring Joyce Valenza, speaks to the resources students require to locate good online information and the skills required to do so - not just from the free web but from the online databases. 

They Might be Gurus: Teen Information-Seeking Behavior (pdf) by Joyce Valenza  maintains that we must understand how youth connect with information by examining it within four buckets; cognitive, affective, social and physical. Students may have great technical skills but they lack the ability to navigate the web environment effectively.

Locating Resources On the Web

Before students begin searching on the web they should have a clear understanding of the medium in which they are working. Although this tutorial, Welcome to the Web , is meant for primary students middle years and high school teachers should review the points presented to ensure that their students understand things such as the difference between the internet and the world wide web and terminology such as 'browser', hyperlink, etc.

Understanding the difference between search engines and search directories:

Search Engines
Search Directories

Search engines create their listings automatically. Search engines crawl the web, then people search through what they have found.

Recommended Search Engines

Search Engines Features Chart

A directory depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search looks for matches only in the descriptions submitted.

Power Search Techniques

Successful searching involves two key steps. First, you must have a clear understanding of how to prepare your search.

  1. You must identify the main concepts in your topic and determine any synonyms, alternate spellings, or variant word forms for the concepts.
  2. Second, you need to know how to use the various search tools available on the Internet. For example, search engines (e.g., AltaVista) are very different than subject directories (e.g., Yahoo). Even search engines themselves can vary greatly in size, accuracy, features, and flexibility.

"The Searchies" A WebQuest
Students are divided into small groups to become expert in one search tool. After examining and testing that tool, they are asked to prepare an advertisement which will sell their search tool's best features to the class so that it may win one of the revered "Searchie Awards." They must also present the small print, or the negative features of the tool. The winners of the Searchies will be determined by the class following the student presentations. Joyce Valenza

Typically most students begin with a very broad search topic. Quintura provides a visual look how they can narrow and focus their search.

After entering the search term, Quintura presents a tag cloud of words. Moving the cursor to the word that most closely matches the search term causes the to cloud to rearrange around that term. You glide though the Internet this way, until you have ’steered’ yourself to the best results; even if its something you did not know was there when you began your search.

Search Engines

Search engines are the World Wide Web's equivalent of a library catalogue. However, because of the enormous size of the Web, no search engine includes everything that is on the Web. Just as there are different ways to search for a book in the library, there are different ways to locate resources on the internet.

Searching the Invisble Web

face behind spider web eyes closedThe "visible web" is what you see in the results pages from general web search engines. It's also what you see in almost all subject directories. The "invisible web" is what you cannot retrieve ("see") in the search results and other links contained in these types of tools. The invisible web is also referred to as the Deep Web .

There are many Web pages that can't be indexed, or information that's available via the Web but isn't accessible by the search engines. This is the stuff of the Invisible Web.Why can't some pages be indexed? The most basic reason is that there are no links pointing to a page that a search engine spider canfollow. Or, a page may be made up of data types that search engines don't index - graphics, CGI scripts, Macromedia flash or PDF files, for example.

But the biggest part of the Invisible Web is made up of information stored in databases. When an indexing spider comes across a database, it's as if it has run smack into the entrance of a massive library with securely bolted doors. Spiders can record the library's address, but can tell you nothing about the books, magazines or other documents it contains. From The Invisible Web by Chris Sherman.

Search Tools for the Invisible Web

Educators who want to teach their students about the buried treasures of the Web should prepare a list—or a page on their library's Web site—of the most effective Hidden Web tools.

Using Google to Search the Invisible Web

If your students are going to use Google they can use it to locate searchable databases by searching a subject term and the word "database". If the database uses the word database in its own pages, you are likely to find it in Google and it is more likely to contain information that is useful to your students

For example a search for the terms minerals + "data base" turned up two great data base resources without the commercial minerals resources.

Visual Search Engines

Visual Search Engines

Standard search engines are great for finding individual Web pages to answer specific questions. But their results lists do not help you to understand a field in general. A visual search engine clusters results, and in doing so gives you a better overview of a field. These are useful tools that can be used to help students narrow and focus their searches.

After you enter your search query, you are presented with a tag cloud of words that looks like a just-finished Scrabble game. Moving your cursor to the word that most closely matches what you are looking for causes the to cloud to rearrange around that term. You glide though the Internet this way, until you have ’steered’ yourself to the best results; even if its something you did not know was there when you began your search.

There are other visual search tools including searchChrystal , Grokker , Clusty and KartOO - the following articles provide a review and a comparison of each.

My favourite of the search engines reviewed is Quintera - the adult search engine. It was the least confusing to view and to follow. I quite like the way it which it displayed the results for the term on which I hovered almost immediately on the right hand side of the page.
