Using web-based knowledge management systems has become the mainstream when enterprises adopt the strategy of knowledge management. With the accumulated amount of materials, the issue of information reuse is emphasized, and how to properly design a knowledge management system to improve the efficiency of information reuse is becoming extremely important. In the past there were two approaches for improving the efficiency of information reuse. One is knowledge map that focuses on information retrieval to promote the efficiency, and the other is usability of Human-Computer Interaction that focuses on the effect of different information representation styles and the user's liking. According to Task-Technology Fit, the greater the degree of adherence to an ideal fit profile, the better the performance. In this study we discussed the impact of information presentation styles on information reuse with different reuse tasks on knowledge management systems. The study is intended as an experimental design to investigate the impact of information presentation styles on information reuse within a knowledge management system. We use an experiment involving 83 subjects. The results of this study indicate that information presentation styles have a significant impact on information reuse. We found that for retrieval tasks, the impact on information reuse would be enhanced with the hierarchical presentation style. Additionally, the result also shows that when increasing the complexity of the task, information presentation styles have no differences to the impact on information reuse. And according to the results of two kinds of questionnaires, the users all had higher liking and partialities for the hierarchical presentation style. Finally, suggestions for the vision information design based on the results of this study are provided.
