A concept that has great ramifications when using the internet is the difference between recall and precision:.
l). "Precision" issues emerge due to homonyms, idioms, multiple uses of works and rewording of phrases. For example Lycos recalled a site on black and white physiography "Bill's Burning Man" and "Evaluation of Carbon Black Slurries as Clean Burning Fuels."
Just as we learned which dictionaries in our collections include foreign terms within the body of the work and which contain a separate listing we will need to have a clear understanding of how the major search engines work. Here are a few examples that illuminate the scope of the searching problem:
Even novices know that some servers will be down for repair, are backing up or are unavailable due to heavy use. One search netted me the frustration of finding the 8 of the first 10 apparently relevant sites had "no data available on server!" Perseverance pays off; the net user who is not willing to invest some learning time will most probably leave in frustration.
When working with students we've all heard the wail, "There isn't anything here!" Upon further investigation, we find that they have misspelled the keyword. However, as an experiment, I entered the misspelling "white AND supremecy" [sic] in AltaVista and 23 sites were returned. Most likely a student would think that they had found what they were seeking and not ask for help.
About one in ten of the returned sites on another search were links to talk shows or to specific news articles which cannot be accessed without paying a fee. Taylor Subscription Talk was one such service that charged $10 for 10 hours of "listening" time. The readers could choose from a long list of broadcast topics but to order took 2 weeks.
Scrolling through some of the long lists was time consuming as the relevance to the church burnings was not always obvious. I was tempted to give up on it. But when the search probed "deeper" into the links first suggested, the rewards were quite good. This is where thinking skills strategies need to be stressed. Only by associating very general topics (e.g. Racial Hatred) with the specific topic (Black Church Burnings) was I able to find productive links.
Originally I thought that the key words "black," "African-American" or "Afro-American" were crucial in my search on church arson. However, one government web page which was rated "low confidence" included the general profile of victim churches and a list of how to prevent violence. There were no references to race in it all but it supplied excellent information.
Result lists are artificially expanded when newsgroups are included. (Note, these personal opinions can provide fruity and divergent points of view.) Some messages are returned only because the keyword is found in "next " and "previous message." Be sure you and your students know how to follow a thread . (A thread is the chain of response messages that contain or address the same topic or subject. They are made by "replying" to a message in newsgroup.
This example began using AltaVista's Advanced Search Form. It's the favorite engine of many educators.
