Purpose of Our Project 4 To construct the basic information tool for recording various events, researching and analyzing social phenomena based on the conceptual model of Reki-Show. Aug. 24, 2005 Copy Right: Reki-Show Authoring Project, KEIO Univ. , Japan
Requirements for Reki-Show Authoring Tools 5 � Operability to handle spatiotemporal dataset � Spatiotemporal database is not easy to use for almost every researchers and students in the field of social science. � They don’t have efficient way to handle spatiotemporal dataset by using popular software.(i.e. Microsoft Excel, Access, etc.) It is not impossible , but is annoying . � Improving operability to handle spatiotemporal dataset is required. Intermediate Chart Excel Worksheets Subject Spatiotemporal Intermediate Map Dataset Access GIS Database Worksheets Chart Reki-Show Map Aug. 24, 2005 Copy Right: Reki-Show Authoring Project, KEIO Univ. , Japan
Requirements for Reki-Show Authoring Tools 6 � Capability to visualize spatiotemporal multidimensional information � Usually, social science data is represented as spatiotemporal multidimensional information. The number of dimension vary by the field of concern. � To visualize spatiotemporal information by using legacy software, we have to reduce spatial information or temporal information. Because, legacy software are not fitted for multidimensional data visualization. � A tools designed for visualization of spatiotemporal multidimensional information is required.

Applied Example -1 10 � Visualization of Peasant Riots in 18th~19th century of Japan � In the late of Edo-era(1840~1868), peasant riots occurred frequently in every part of Japan. � We categorized the cause of riot as follows: � Market originated(unfair pricing, corner, etc.) � Heavy tax � Other reason � Also classified the level of violence as follows: � Direct Appeal (non violent) � Direct Appeal (violent) � Escape � Riot � Uprising � Data source: � Koji Aoki (1971): ”The General Chronicle of Peasant Riot” , San-ichi Press, Japan Aug. 24, 2005 Copy Right: Reki-Show Authoring Project, KEIO Univ. , Japan
Data Visualization by Crono-Matrix Viewer 11 TEN-MEI Famine, 1782-84 TEN-PO Famine, 1832-38 The end of EDO era, 1864-68 Level of violence Market originated Heavy tax Other reason Spatial Distribution of Riots Aug. 24, 2005 Copy Right: Reki-Show Authoring Project, KEIO Univ. , Japan
Applied Example -2 12 � Visualization of Yukichi Fukuzawa’s Logbook in Crono-Matrix Fukuzawa’s Logbook � Yukichi Fukuzawa(1935-1901) is one of famous enlightenment person in 19th century of Japan. He wrote a lot of books for young people and translated various western books. He also founded KEIO University. � Fukuzawa went a round trip to Europe in 1862 as a translator of embassy. He wrote a detailed logbook of the travel, “Seiko Nisshi”. � This logbook is a good example of Reki-Show Dataset; spatiotemporal descriptive information.
