Massive Data Input System for Geographical Origin Identification System of Vegetables using Trace Element Compositions

摘要

As co-research with agricultural chemists, we developed a vegetable geographical origin identification system using difference of trace element compositions of vegetables from cultivated districts. The system works well to identify geographical origin of vegetables in our previous works. However, there are some problems to gather trace element compositions data Generally, measured trace element data contains outlying observations, and normally an experimenter removes these kinds of outlying observations. However, in case of massive data must be registered in short time, checking of measured data by hand is an obstruction to automatically registration. Therefore, in this paper, we describe about trial to introduce outlying observation detector using Smimov test Also, we describe about how to extract measured data in electronic form from measuring instruments such as ICP-MS which are normally closed system.
