User-centered evaluation of question answering systems

With the rapid growth of the Internet and database technologies in recent years, question answering systems (QAS) have emerged as important applications. As most evaluation models focus on system-centered evaluation, user-centered evaluation has attracted little attention. Although many QAS have been implemented, little work has been done on the development of a user-centered evaluation for QAS. User-centered evaluation is used to understand a user's needs and identify important dimensions and factors in the development of an information system in order to improve its acceptance. The purpose of this study is to develop a user-centered evaluation model for QAS from the user's perspective. The proposed user-centered evaluation model provides a framework for the design of question answering systems from the user's perspective to enhance user satisfaction and acceptance of QAS.
