how query cost affects search behavior translated in JP

I'm a university student in master degree. My research focus is spoken conversational seeking. I've been looking for information retrival related to query costs in order to decide my focus. And I have to make a presentation about research what I want to introduce in my class. This thesis shows very interesting result, so I like it. Therefore I translated from EN to JP. caution:This is summary,not include detail.

エリで多くの文書を調査するというもの
Q.どうやって明らかにする?
Q.結果は?
・36人の大学生を対象に被験者内実験.
・3つの検索タスクを与え,各タスクにつき10分間検索.
・高コスト,ベースライン,低コストのインターフェースを用いて,クエリ
発行平均数,評価文章数,検索ページの深さ等の指標で比較分析.

研究の新規性
対話型情報検索(IIR)する際,ユーザには様々なコストが発生する[2,3]
多くの研究は
クエリ発行数,調査された文書数などを評価しているが,
ユーザがシステムを使う時に発生するコストがどのような検
索行動を作っていくかをモデル化するところが新規性である
