My current major work is development of virtualization nodes (routers).
This is part of a research project on "New Generation Networks"
conducted by NICT.
I am also interested in
developing a new voice-communication medium called
voiscape, which can be more widely used than telephone or conference systems.
My work until fiscal year of 2001 was on active networks
(computing networks), policy-based networking, and
internet QoS (quality of service). Until around March 1999, I have been
studying and developing methods for searching and reorganizing
information placed on the Internet, e.g., WWW or online encyclopaedia,
especially on
"thematic search" / "axis-specified search".
I believe my lifework that connects most of the above researches is "fusion of analog
and digital", or "fusion of symbols and subsymbols".
These research-related information can be accessed through
"research themes overview" or
"research topics".
My paper list is in "paper summary".
Recently, I started a blog.
This blog contains information not limited to my research, but it contains much less
information than the Japanese version.
My Current and Past Research-themes (reverse order)
- voiscape: a virtual "sound room" based communication medium
- Development of a new communication medium by which two or more persons can talk each other by
using a virtual sound space based on spatial sound technology.
- Active Networks, Policy-based Networking, and QoS Guarantee
- Research on development of programmable and virtualized network, and methods of combining (composing) policies, or on component-based policies.
- Axis-Specified Search (Thematic Search)
- Development of search methods in which users (searchers) specify an axis of search in addition to keywords and in which the search results are arranged along the axis.
- Self-reproduction of Web pages
- Small-scale research on developing a method for reproducing and displaying exactly or almost the same Web page as the original.
- CCM: Chemical-Computation Model
- Research on a computation method in which only local information is used, i.e., each action in CCM refers only a few data, and there is no global plan (i..e., no program) for the computation.
- RACA: Randomized Asynchronous Cellular Automata
- Small-scale research on asynchronous and non-deterministic (i.e., randomized) cellular automata, but an article in Wikipedia described it (in March 2007).
- Logic/Symbolic Vector Processing
- Development of methods of vector processing
of logic programming languages and/or symbolic vector processing etc.
- Programming Linguistics
- Research on programming languages (programs) using the methods of linguistics.
- Programming Language Processing for Vector / Parallel Computers
- Development of a programming language and compilation techniques for a MIMD computer and vector (SIMD) supercomputers.
- Programming Language Processing for Scalar Computers
- Development of compilers of programming languages, SIMPL and Pascal.
