| What’s the Difference between the World Wide Web and the Internet? | The terms Internet and World Wide Web (WWW) are often used to mean the same thing. Actually, there are distinct differences. The Internet is a network of networks that connects millions of computers together. Information (like e-mail, chat, instant messaging, and file transfers) is communicated over the Internet via a variety of languages known as protocols. The World Wide Web is just one of the services deployed on the Internet, using specific protocols (like http or hyper text transfer protocol). The WWW is made up of Web servers that store and distribute Web pages, which can be viewed using Web browsers, like Netscape or Explorer. The core of Web technology is the hyperlink (the URL address), which can connect documents to each other by clicking a link. |
| What are Search Engines and Meta
Search Engines?
|
Search Engines scan an index of web sites and list those sites that match the criteria you specified in the search box. This is similar to looking for keywords. Examples of search engines are Google http://www.google.com, Ask.com http://www.ask.com, Live Search http://www.live.com, and Yahoo http://www.yahoo.com. Meta Search Engines search through the indexes of individual search engines simultaneously. Examples of meta search engines are: Dogpile http://www.dogpile.com, Alltheweb http://www.alltheweb.com, Kartoo http://www.kartoo.com and Search.com http://www.search.com. |
| What are Search Directories?
|
Subject directories are collections of websites that include World Wide Web resources selected by people who are sometimes experts in their field. These sites are arranged and classified in a logical manner. INFOMINE http://infomine.ucr.edu is a scholarly subject directory. The DMOZ Open Directory Project http://dmoz.org is a comprehensive subject directory that is international in scope. Yahoo http://www.yahoo.com is both a search engine and a subject directory. |
| What is Google Scholar?
|
Google Scholar http://scholar.google.com is an example of a search engine that covers scholarly literature. Results may include abstracts and full text articles. Keep in mind that a significant amount of the results indexed by Google Scholar are not online or are available only by subscription. To enable direct links to full text owned by UCF via SFX, click on ‘Scholar preferences’ (located to the right of the search box). At ‘Library Links’ type in University of Central Florida, then click ‘Find Library’ and check the box ‘University of Central Florida Libraries (Full Text via SFX @ UCF)’. This will allow you to link from Google Scholar and access subscription articles owned by UCF (using your activated library ID number). |
| Is there really an Invisible Web?
|
Invisible or Deep Web are sites or databases that are not accessed by search engines. You locate the site and then use the search feature on the site to locate information. Examples of portals to these sites are Complete Planet http://aip.completeplanet.com or Direct Search http://www.freepint.com/gary/direct.htm. |
| Is there a way to only get pictures
from the web?
|
Many search engines have features that enable users to search for images on the Internet. Both Google http://www.google.com/advanced_image_search and Yahoo http://images.search.yahoo.com/search/images/advanced have advanced image searches that allow users to search for pictures and images by size, coloration, and domain (government sites, education sites, etc.). |
| Where should I go to get more help?
|
The rules for using Internet search tools differ, so check to see what HELP is provided. Try the site Search Engines Features Chart http://www.searchengineshowdown.com/features for additional information. A single search engine may cover a fraction of the World Wide Web, so don’t rely on just one search tool. World Wide Web searching is different from searching a database. The results are constantly changing. |
| Why is it important to critically
evaluate information found on the Web?
|
Anyone can have a web page and publish information on the Web. The Web does not have reviewers or editors; No quality control. There is no guarantee that the information you find is accurate. Many pages are not updated. |
| What is an easy way to gain
information about a site?
|
You may get a hint to a website’s intention by looking
at the extension (or domain) in the URL or web address:
Personal page – look for a personal name after a tilde (~jsmith) or % sign, or sometimes the words member or users |
| How do I identify and get
information about the “author”?
|
Is there is an author? What do we know about the author? Is he/she an authority in the field? What is the author’s occupation? Can you find information about the author in another source, e.g. directory or encyclopedia? Is there is an organization or group connected to the web site? What can you find out about the organization? Look for an “About Us” link. If you end up with just a document, look for a link to “home” for more information on the web site. Who pays for the web site? |
| How do I decide the “purpose of the
site”?
|
Is it to explain? Inform? Persuade? Sell? Look at “About Us”, “Background” and/or Mission links for more information about purpose of site. Is the site biased? Is the information accurate? If you’re not sure, check another source. Is it scholarly? Are there references? |
| Where do find out when the document
or web site was written, created or revised?
|
Look for "last updated" date. How recent is the information? Is it too old? Are the links active and accurate? For more information consult the Resource Discovery Network’s Internet Detective website: http://www.vts.intute.ac.uk/detective |
| Isn’t everything on the web free for
everyone to use?
|
Consider everything you find on the Internet/Web as
copyrighted unless otherwise stated. You must give credit to the author
or organization that created the web site, document, graph, image, etc.
Always document/cite (gives the author credit) the sources you use; Direct quotes, Ideas you use, Paraphrasing Documenting allows other people read in more depth from the sources you used in your paper. Documenting demonstrates the depth of your research. For more information, see the UCF Libraries Copyright Policies and Guidelines website: http://library.ucf.edu/Administration/Policies/Copyright/default.asp |
| How to I format citations for
Internet information?
|
See the APA Format Module for more information on using
the APA style to cite your sources. Remember – When you cite an Internet/Web source always include the URL (web address). Use the complete address and include the http://.If you are citing a document within a web site use the URL for that document, for example:
