Abstract
RIO-DB (Research Information Database) is multimedia database that is accumulated by many AIST (National Institute of Advanced Industrial Science and Technology) R&D projects. Knowledgebase of underwater cutting technique is part of the underwater processing technique database that is developed and released as one of RIO-DB project. Authors have preserved the experimental data necessary for development of practical underwater mechanical processing to construct, to demolish and to maintain structure. Many movies and pictures of welding and cutting process have been conserved in this knowledgebase from the viewpoint of importance to understand phenomenon in the process. In addition to an abridgement and a basic version of the knowledgebase, we provide the detailed version that more information is accumulated and the user interface is improved. In this paper, we make a summary report of the progress and future developments of this project.
