Abstract: The input means 181 accepts inputs of test data, a hierarchical structure in which a node of bottom layer represents a target class, and a classification score of a seen class as the classification score indicating a probability that the test data is classified into each class. The unseen class score calculation means 182 calculates the classification score of an unseen class based on uniformity of the classification score of each seen class. The matching score calculation means 183 calculates a matching score indicating similarity between the test data and each class label. The final classification score calculation means 184 calculates a final classification score indicating a probability that the test data is classified into the class so that the larger the classification score of each class, and the matching score, the larger the final classification score.

Abstract: A column meaning candidate selection means 303 selects a candidate for meaning of a column whose meaning is to be inferred. A column similarity computation means 304 computes, for each candidate for meaning selected by the column meaning candidate selection means 303, a score indicating a similarity between the selected candidate for meaning and meaning of each column other than the column whose meaning is to be inferred contained in a table. A column meaning identification means 305 identifies meaning of the column whose meaning is to be inferred from the candidates for meaning of the column with use of the score computed by the column similarity computation means 304.

Abstract: A plurality of substrate holding members and a substrate pressing member are disposed on a rotation stage at a peripheral portion. The substrate pressing member includes a magnet and is pivotally supported by the rotation stage. A ring-shaped permanent magnet is located below the rotation stage and forms a ring around the rotation axis of the rotation stage. When a substrate mounted on the rotation stage is rotated and processed, the ring-shaped permanent magnet is positioned in the vicinity of the magnet of the substrate pressing member. This creates a magnetic force between the magnets, causing the substrate pressing member to pivot so that the substrate pressing member contacts the edge of the substrate with a predetermined amount of pressure.
