Mediated information retrieval in Web searching



This study investigated whether the existence of either the mediated condition through a collection in a specific domain or the combined display of a clustered structure and a linear ranked list of search results would affect the three main measures of the user's Web searching behaviors: effectiveness, efficiency, and usability. That is, mediated access through a structured collection helps the user explore a small well-structured document collection covering a specific subject domain in order to clarify her/his information needs before search on the World Wide Web. The results of the study demonstrated that all the measures had interesting results via the adaptive process on the system and the search task. The findings of this research contribute to a better understanding of how the mediation system or the combined display supports a Web information user.
