| Abstract: | Compares the
searching capabilities of two search engines (Google and Yahoo) and two
metasearch engines (Metacrawler and Dogpile) on the basis of the precision
value and relative recall. Fifteen queries which represented a broad range of
library and information science topics were selected and each query was
submitted to the search engines and metasearch engines. The first 100
results in
each scenario were evaluated and it was found that search engines did not
achieve higher precision than the metasearch engines. It is also found that
despite the theoretical advantage of searching the databases of several
individual search engines, metasearch engines did not achieve higher recall.
The results of the study offer guidance for internet surfers to choose
appropriate
search tools
for information retrieval. It also provides some inputs to search engine
designers to make search engines’ search
capabilities
more efficient. |
