摘要

A fundamental challenge to user modeling for information retrieval (IR) systems is to decide what user knowledge should be included in user models. Such knowledge should be able to enable an IR system to effectively predict the user's search behavior/performance and to effectively personalize the search process based on the user's model. A better understanding of user characteristics and user behavior will provide a basis on which individualized IR systems can be designed. This study investigates the roles of users' subject domain knowledge and IR knowledge in their search behavior and performance.
