Purpose of Our Project
To construct the basic information tool for
recording various events, researching and
analyzing social phenomena based on the
conceptual model of Reki-Show.

†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.

†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.

†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

† Visualization of Yukichi
Fukuzawa’s Logbook
Fukuzawa’s Logbook in Crono-Matrix
† 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.
