Abstract: To display information providing an insight required by a user, provided is an information processing apparatus (1) including: an obtaining section (11) that obtains an evaluation dataset and context data; a relevance calculation section (12) that calculates a relevance between the context data and a constituent element of the evaluation dataset; an evaluation section (13) that carries out evaluations of a plurality of insight subjects generated with reference to the evaluation dataset and the relevance; and a display section (14) that displays information relevant to the insight subjects.

Abstract: To evaluate whether a visualization candidate of data provides an insight required by a user, an information processing apparatus (1) includes: an obtaining section (11) that obtains an evaluation dataset and context data; and an evaluation section (12) that carries out evaluations of a plurality of insight subjects in relation to the context data, the plurality of insight subjects being generated with reference to at least the evaluation dataset.

Abstract: The information processing device 1X mainly include a feature acquisition means 15X, a universal feature conversion means 16X, and a related user identification means 18X. The feature acquisition means 15X is configured to acquire first data set specific features, which are user's features specific to a first data set and second data set specific features, which are user's features specific to a second data set. The universal feature conversion means 16X is configured to convert the first data set specific features and the second data set specific features into universal features which are features in a universal feature space for the first data set and the second data set, respectively. The related user identification means 18X is configured to identify a user related to the first data set and the second data set based on the universal features of the first data set and the universal features of the second data set.

Abstract: The information processing device lx mainly includes a combination target data acquisition means 16X, a combination target element determination means 17X, and a data combination means 18X. The combination target data acquisition means 16X is configured to acquire combination target data that is data of a second data set to be combined with data of a first data set. The combination target element determination means 17X is configured to determine a combination target element to be combined with the data of the first data set, based on a function value of each element of the combination target data. The data combination means 18X is configured to combine the combination target element with the data of the first data set. X combines the element to be combined with the data of the first data set.

Abstract: It is possible to detect an insight between a plurality of data sets. An information processing apparatus (1) includes: a classification unit (11) that groups, by insight to be detected, a plurality of insight subjects each being data generated from each of a plurality of data sets by associating a plurality of data items contained in each of the plurality of data sets with each other; and an evaluation unit (12) that calculates, for a combination of the plurality of insight subjects which have been grouped, an evaluation value for determining the presence or absence of an insight.

Abstract: An information processing device acquires target data, and converts the target data to an embedded vector indicating a latent feature quantity of the target data. Also, the information processing device searches for data similar to the latent feature quantity of the target data as candidate data, and applies a predetermined process to the candidate data to assign a rank to be combined with the target data, for each of the candidate data. Then, the information processing device outputs a result obtained by combining the target data and the candidate data based on the assigned rank.
