Targets and results from phase one and two of the fifth generation computer systems study

This article presents an introduction to the fifth generation computer systems.

Fifth generation computers are under development to meet the knowledge information processing needs for the advanced information-oriented society of the 1990s. This clearly requires overcoming the technical limitations of conventional computers. A fifth generation computer requires problem solving and inference functions for inference of solutions to problems from accumulated knowledge, knowledge base management functions for acquirement and retrieval of knowledge, intelligent interface functions for fluent conversations using natural language, drawings, images, etc., and intelligent programming functions for automatic conversion of problem specifications submitted in natural language, drawing etc., into efficient programs.

Fifth generation computers with these functions will have far-reaching impact finding applications in all areas of industry and society. However, research and development (R&D) of these computers requires an extremely wide variety of leading-edge technology, and the risks are high. Accordingly, a long-term R&D plan was established for this project that extends over ten years with the initial stage lasting from 1982 to 1984, the intermediate stage from 1985 to 1988, and the final stage will begin in 1989 and the project will end in 1991.
