Abstract: For each of one or a plurality of types of samples, a database is constructed in which a sample identification tag and data belonging to at least two types of categories out of Categories (1), (2), and (3) are stored in association with each other. Data to be used as training data in supervised learning is selected from the database. At this time, one or a plurality of types of data is selected as an explanatory variable from one of the categories. Further, one or a plurality of types of data is selected as an objective variable from the other category. Then, training data is generated in which data corresponding to the selected explanatory variable is served as input and data corresponding to the selected objective variable is served as ground truth output. Category (1) is a plurality of types of samples relating to a production method of the sample, Category (2) is a plurality of types of samples acquired by analyzing a sample by one or a plurality of types of analyzers, and Category (3) is a plurality of types of physical property data that are information representing sample characteristics.

Abstract: A data processing method includes a step for a computer to collect analysis file sets from multiple types of analyzers, the analysis file sets each including analysis data by the analyzer, a step for the computer to store the plurality of collected analysis file sets in a database with the analysis file sets sorted into corresponding collections for each material, and a step for the computer to form a subset by extracting an analysis file set in which a type of the analyzer, preprocessing conditions of a sample measured by the analyzer, and measurement conditions of the sample all match, from the collection.
