| Summary: | 碩士 === 國立清華大學 === 工業工程與工程管理學系所 === 106 === As people are interested in the tendency of a specific issue, they usually search for the relevant reports related to the issue through the Internet. They have to collect and organize the contents of these reports to acquire the trend information of the issue that they concern. However, the trend of an issue might exist in several distinct reports. As a result, they have to spend time in browsing and organizing these decentralized trend information. On the other hand, the reports of trend information are usually presented in text form; therefore, it is not easy for readers to efficiently acquire the trend distribution of the issue. Owing to the above problem, this research develops a model for integration and visualization of trend information. The proposed model can be used to integrate and visualize similar trend information. By applying the model, the similar trend information can be clustered and each cluster of trend information can be visualized to reveal the trend distribution.
