At least one processor included in a question generation apparatus carries out: an acquiring process of acquiring a plurality of character strings and pieces of text; a question generating process of generating, for each of the plurality of character strings, a question an answer to which is that character string; an ambiguity judging process of judging, for each of a plurality of questions, whether there are a plurality of answers to that question; and an outputting process of outputting a question which has been judged to be the question to which there are a plurality of answers.

Question generation apparatus, question generation method, and recording medium for AI-assisted decision making

The input meansaccepts 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 meanscalculates the classification score of an unseen class based on uniformity of the classification score of each seen class. The matching score calculation meanscalculates a matching score indicating similarity between the test data and each class label. The final classification score calculation meanscalculates 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.

The acquisition unitB acquires sales request information S, which is request information regarding a sale of data owned by a data owner, from an owner terminalused by the data owner. The determination unitB determines, on a basis of the sales request information S, whether or not there is a customer who demands the data. The notification unitB notifies, in a case where the determination unitB determines that there is the customer, the owner terminalof sales response information Sindicating information regarding the customer for the data.

A column meaning candidate selection meansselects a candidate for meaning of a column whose meaning is to be inferred. A column similarity computation meanscomputes, for each candidate for meaning selected by the column meaning candidate selection means, 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 meansidentifies 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

Meaning inference system, method, and program

Provided is an information provision system that can provide workers with useful information for combining tables, so that even workers with little specialized knowledge can smoothly proceed with the task of combining multiple tables. An input unitreceives input of multiple tables. An identification unitidentifies a pair of columns that are in a combinable relationship, identifies that a pair of tables to which the individual columns forming the pair belong is the pair of tables to be combined, and identifies a combine method of the tables to be combined. An output unitoutputs the pair of tables to be combined, the pair of columns in a combinable relationship, and the combine method of the tables to be combined.
