... Information is being added to the internet at a rate of about 7. ... The real key is to know where and how to find only the information you need. ... The authors of the article conducted research using a Management Information Systems class at Montclair State University. The research concluded that a majority of the students did not realize that when performing an online search, that different engines would return different results.
The authors had three key points in the article: the differences between search engines and subject directories; strategies for searching the internet; and the classification of the information that is retrieved from searches (recall and precision).
Search Engines versus Subject Directories
Search engines and MetaSearch engines are best for the user that needs to locate a very specific piece of information, such as the weather forecast for Denver this Thursday. ... Because the MetaSearch engine searches so much information at once, users may find it difficult to conduct complex search statements and may experience slower response time than with a single Search Engine.
Subject Directories are designed for the user looking for general information. ... However, this also means that the user gets more relevant results. ...
Recall and Precision
When the search engines search the databases, the information that is retrieved can be classified in one of two categories: whether the engine retrieves all the relevant documents and whether the system retrieves only the relevant documents
Kilmer and Koppel (2002) state that recall can be expressed as a percentage of total relevant documents retrieved from all documents.
