Title: A Polymorphic Data Visualization for Spatiotemporal Database

A Polymorphic Data Visualization for
Spatiotemporal Database

Outline of Presentation
  • An Introduction to Reki-Show Authoring Tools
  • Conceptual design of polymorphic data
    visualization
  • Examples of Reki-Show Authoring

3
What is Reki-Show?
-
Spatiotemporal Descriptive Information
4
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.

5
Requirements for Reki-Show Authoring Tools
  • 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 dont 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.

Requirements for Reki-Show Authoring Tools
  • 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
  • Visualization of Peasant Riots in 18th19th
    century of Japan
  • In the late of Edo-era(18401868), 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

Applied Example -2
  • Visualization of Yukichi Fukuzawas 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.
  • Fukuzawas Logbook in Crono-Matrix

Aplied Example -3
  • Large Earthquake in Japan, 1700-2003
  • Historical data Seismic centers of earthquakes
    over magnitude 6.0
  • Time-serial visualization by Crono-Matrix Viewer
    and geographical visualization by ILIAS

14
Major Milestones of Project
  • Beta release of Reki-Show Authoring Tools by
    April, 2006.
  • Software will be downloaded from our Web site.
  • Web Database Inquiry System will be released by
    April, 2006.
  • Multilingual user interface should be supported
    by the end of 2006.
