Drop-down lists with suggested terms on the left in Japanese, and the terms in
English on the right for the explanation purpose
far. Each suggested term is displayed with the number of documents relevant to
the term. When the user clicks one of the suggested terms, a query is executed
and a list of document titles are given in the content area as shown in Figure 3.
The drop-down lists in Figure 4 show the suggested terms came up when the
user typed
kenkou

in hiragana or Japanese phonetic characters. If there exist
more than ten suggested terms, ”show all candidates” link is displayed in the
lower right of the drop-down list as in Figure 4(a). All the candidate terms can be
listed by vertically extending the drop-down list when the user clicks the show-
all-candidate link. The terms in Figure 4(a) are suggested and ranked taking
account of the domain vocabulary. They include not only narrower terms such
as the first candidate
kenkou-shindan
that means 'medical examination,' but
also related terms such as the second candidate
kenkou-hokenshou
that means
'health insurance card.' The dynamic term suggestion here helps the users to
follow the Web search practice that is to modify queries from broad to narrow
formulation via adding terms for more precision [9].
In contrast, Figure 4(b) shows suggested terms came up simply relying on
generic vocabulary without regard to any domain-specific terminology. In this

One of its possible meanings is 'health.'
