"Cyberworlds" is a term that has defined to explore the world of information systems. I have been in pursuit in the research of such spaces since 1968 and established the Information Science Subcourse of Graduate Faculty of Science, and concurrently as a newly created Information Science Laboratories of Faculty of Science at the University of Tokyo, in April 1970. Later it was realized as the University of Aizu in April 1993 in a historical city of Aizu-Wakamatsu, Fukushima Prefecture.

Since their inception, Cyberworlds has dominated the globe, now most commonly known to us as the internet. However, it includes digital media such that we can lead the area of digital media as seen typically in intensive use of digital media in TV broadcasting. Furthermore, research into cyberworlds can give us a better understanding of the principles and growth of global information systems such as enterprize information management systems, financial and hospital information systems, e-commerce systems, and digital government systems

In order to understand Cyberworlds, we must understand Information Systems (IS). IS is a derivation of Information Technology (IT). The core of IT is CS (Computer Science), IS is a major application area. IS includes basic social information infrastructure. The graduate curriculum on IS for Master Courses has been updated by ACM and IEEE Computer Society in 2006 aim to work to cover ever increasing high demand embedded systems technology including those for portable devices such as cellular phones that now serve for digital media as seen in one-seg TV. There has been no Doctor Course IS curriculum. In the development of our technological age, unlimited funds have been poured into varieties of projects without any meaningful results. As usual, such projects start from requirement process specification, however ending with no meaningful architectural design. To automate and to eliminate the exponential growth of integrating IS by making it linear, we have to define the architecture of information systems clearly for both machines and human beings. Only ways to do it are, as stated above, through high level abstract algebra to compute and hence by algebraic topology.

Current software development has progressed to technology based on embedded OS plus general cross platform development environments, and now to that of model-based semi automated generation such as those based on executable UML2.0. However, all of the current methods utilise the traditional development of technology based on hardware dependent implementation has been suffering from economical troubles of longer development periods of software than those of ever shortening hardware life cycles. A completely novel approach via an incrementally modular abstratction hierarchy (IMAH) grounded on algebraic topology is shown to overcome this fundamental difficulty.

The true generality of global information systems on the Web is demanding a very versatile and generally applicable framework for architectural design, forcing us to abstract global information systems to extract the cores. Hence, we have to exploit from most abstract mathematics of topology, and to compute, it has to be algebraic. That is the reason we have to resort to algebraic topology to achieve the goal. The the following algebraic topological framework, IMAH, is the core of the technology. His personal research reveals that by wisely applying high level abstraction via an incrementally modular abstratction hierarchy (IMAH), these applications can be reduced to only one software to generate individual applications automatically while combinatorially exploding testing are becoming unnecessary based on invariant preservation via equivalence relations in quotient and adjunction spaces.
