Overview
Our goal is the research and development of graphics and
visualization techniques for trend analysis and information
retrieval of various large-scale data.
World Wide Web is a good example of the large-scale data.
Currently there are more than a billion webpages on the internet.
It is not generally easy to see the overview and trend,
and extract desired messages, from such a huge hyperspace.
The above figure shows an overview of a website.
In the figure, each rectangle denotes a webpage.
Heights of the rectangles denote the access frequency,
and colors of them denote the update time.
Currently we are studying about visualization techniques
for further large-scale data, complicated relational data,
multi-valued data, and drastically time-varying data.
We are also aiming the visualization techniques
not only for websites but also the following fields:
- Computer process and network monitoring.
- Analysis of scientific sample data (such as DNA sequence).
- Trend analysis of financial network.
- Monitoring of traffic and communiation systems.
- Analysis of social organizations and human resources.
- Arrangement of large-scale text and image data.
