The Web has become a major source of information
that people and organizations utilize to address a variety of
information issues. There is a growing body of literature
examining how people search the Web [1-3], providing
insights into how humans conduct Web searching.
However, non-humans now conduct at least a portion of
Web searching. These non-humans include agents,
automated processes or spiders that search the Web. For
this paper, we refer to spiders, softbots, meta-search
applications and other automated information gathering
processes all as agents.
