碩士 === 國立臺灣大學 === 資訊工程學研究所 === 105 === “The Veritable Records of Qing” is a comprehensive historical records. It is a chronologically arranged collection of important issues with the day-to-day routine activities of the emperor and of memorials, including the submission or appointment of significant officials, imperial decrees, demographic information, cargo delivery and expeditions. It is compiled through emperors’ order, and it is also with strict structure. Therefore, it provides a valuable source for historians who conduct research on Qing dynasty. However, when scholars do research in “The Veritable Records of Qing”, to extract a small portion of relevance issue from this huge records can be a problem. Although after these historical records are digitalized, scholars can use keywords search to find relevant historical text. Nevertheless, if these relevant historical texts of interest do not contain the used keywords, it cannot be found by the tool. In this research, a method for finding relevant historical texts is proposed. It will compute the level of relevance between each text, instead of using keyword search. Based on some selected texts of interest by the researcher, the methods will compute the level of relevance between the selected texts and the potential texts of interest. After the computation, the potential texts of interest are listed by its rank. Researchers can choose texts they are interested in and send out their result. Having the feedback texts chosen from researchers, the method will continue on the next iteration, and find out the texts that are even more likely to be of interest of the researchers. In 1990s, scholars retrieved the supposed texts relevant to “Taiwan” from “Veritable Records of Qing” manually, and then edited them into “Veritable Records of Qing-Taiwan Selection”. In the research, this edition and “Veritable Records of Qing” are adopted to examine the performance of different relevance algorithm on general historical records. Next, a system based on relevance feedback algorithm is proposed to provide users or researchers with an interface to search for relevant texts in huge historical records. Finally, the research used “Veritable Records of Qing-Taiwan Selection” as an example to find out more relevance historical texts from “Veritable Records of Qing” that have not been chosen. The research can be divided into two part. The first part will be deliberating on the method proposed to match the two digitalized historical records mentioned above. Besides, different ways for computing relevance level in texts and branch mark of these methods on the performance on these two historical records will be introduced. While in the second part, the relevance feedback system based the most well-performed method in the experiment is introduced. Finally, with some testing by historians, the texts found out through this method are analyzed and observed
