Separation of public people and scientists are recognized as important issues. The progress of research is so fast and diverse that even a specialist is not capable of investigating the interdisciplinary area and the unfamiliar field. This paper introduces a visualized search system of KAKENHI, the scientific research fund by Japanese government. We use KAKENHI reports as a basic information on science and technology of Japan.The system extracts the words from the titles and the abstracts of KAKENHI projects, as well as technical terms, research fields, researchers, organizations and research periods. The words are displayed as nodes of a graph with different colors according to their attributes. The co-occurrence relation of words are displayed as edges of the graph. The distinction of words' attribute makes it easy to guess "who, what, with whom and where" according to the intension of search. This paper explains how the system works and show some examples of exploratory search.
