In spite of the radical enhancement of Web technologies, many users still continue to experience severe difficulties in navigating Web systems. One way to reduce the navigation difficulties is to provide context information that explains the current situation of Web users. In this study, we empirically examined the effects of 2 types of context information, structural and temporal context. In the experiment, we evaluated the effectiveness
of the contextual navigation aids in 2 different types of Web systems, an electronic
commerce system that has a well-defined structure and a content dissemination
system that has an ill-defined structure. In our experiment, participants answered a set
of postquestionnaires after performing several searching and browsing tasks. The results
of the experiment reveal that the 2 types of contextual navigation aids significantly
improved the performance of the given tasks regardless of different Web systems
and different task types. Moreover, context information changed the users’
navigation patterns and increased their subjective convenience of navigation. This
study concludes with implications for understanding the users’ searching and browsing
patterns and for developing effective navigation systems. View all 5 works published by Yonsei University |

Abstract: In spite of the radical enhancement of Web technologies, many users still continue to experience severe difficulties in navigating Web systems. One way to reduce the navigation difficulties is to provide context information that explains the current situation of Web users. In this study, we empirically examined the effects of 2 types of context information, structural and temporal context. In the experiment, we evaluated the effectiveness
of the contextual navigation aids in 2 different types of Web systems, an electronic
commerce system that has a well-defined structure and a content dissemination
system that has an ill-defined structure. In our experiment, participants answered a set
of postquestionnaires after performing several searching and browsing tasks. The results
of the experiment reveal that the 2 types of contextual navigation aids significantly
improved the performance of the given tasks regardless of different Web systems
and different task types. Moreover, context information changed the users’
navigation patterns and increased their subjective convenience of navigation. This
study concludes with implications for understanding the users’ searching and browsing
patterns and for developing effective navigation systems.
