Abstract
Scientific Concept Vocabulary (SCV) has been proposed to actualize Cognitive methodology based Data Analysis System: CDAS which supports researchers to analyze large scale data efficiently and comprehensively. In the information model of SCV, all semantic information is related to substantial data and algorisms. Consequently, SCV enables a data analysis system to process semantic information for physics and engineering. Using SCV, it is hoped that CDAS is able to extract semantic information from numerical simulation data. In this paper, the prototype of SCV has been constructed and applied to actual data of numerical simulation in order to confirm the implementability of the system.
