TALON MODULE 6: Finding Periodical Articles
Drawbacks of Keyword Searching
Keyword searching certainly has many positive features, but there are also
some disadvantages to remember as well:
Because you search keywords in more than one field, you will generally locate
more articles than in a subject search (high recall),
but many may not be relevant to what you are looking for (low
precision).
These items are called false hits. For
instance, a keyword search under "apple" may retrieve not only the
fruit but also Apple computers and anyone with that name. "Jurassic" could
get you articles on both the second period of the Mesozoic Era (the time
of the dinosaurs), as well as the movie Jurassic Park.
