A determination device according to the present application has an acquisition unit and a determination unit. The acquisition unit acquires the search queries, which are the search queries input by a plurality of input customers who have input the reference query and input within a predetermined period. The determination unit determines whether a predetermined period is appropriate or not based on the attributes of the input customers who have input search queries or based on whether these search queries satisfy predetermined conditions or not.

An output apparatus according to the present application includes a prediction unit and an output unit. The prediction unit predicts whether or not waveform information having a predetermined context is generated on the basis of detection information detected by a predetermined detection device. The output unit outputs waveform information having an opposite phase to the waveform information having the predetermined context in a case where it has been predicted that the waveform information having the predetermined context is generated.

An output apparatus according to the present application includes an estimation unit, a decision unit, and an output unit. The estimation unit estimates an emotion of a user from detection information detected by a predetermined detection device. The decision unit decides information to be changed on the basis of the estimated emotion of the user. The output unit outputs information for changing the information to be changed.

A determination device according to the present application has an acquisition unit, a categorization unit, and a determination unit. The acquisition unit acquires the search queries, which have been input by a plurality of input customers who have input a reference query. The categorization unit categorizes the search queries, which have been input in a predetermined period among search queries, into a plurality of categories. The determination unit determines whether a categorization result by the categorization unit satisfies a predetermined determination condition or not.

An authentication apparatus according to the present application includes an acquiring unit, a first specifying unit, a second specifying unit, and an authentication unit. The acquiring unit acquires context information on a target user who becomes a target for authentication. The first specifying unit specifies a belonging cluster based on information related to a plurality of cluster groups and the context information on the target user, in each of the plurality of the cluster groups. The second specifying unit specifies, for each belonging cluster based on a classification model used to specify a predetermined candidate user in the belonging cluster specified by the first specifying unit, a candidate user, in a partial candidate user group that belongs to the belonging cluster, who satisfies a predetermined condition. The authentication unit authenticates the target user based on information related to the candidate user specified by the second specifying unit.

Authentication apparatus and method for clustering and authenticating users

An information processing apparatus includes: a model generation unit configured to generate a prediction model for calculating a prediction value related to a probability that a user performs an action on the Internet by operating a user terminal, for each group created by grouping users based on user information; a model selection unit configured to select a prediction model suited to the user from the prediction models; and a prediction value calculation unit configured to calculate the prediction value by using the prediction model selected by the model selection unit.

An information processing apparatus, method, and program that control an electronic data exchange. The apparatus, method, and program involve receiving user information on an information provider or a provider terminal from the provider terminal used by the information provider. The user information received is stored in a memory. In the case of accepting an acquisition request for the user information from a user terminal used by an information user, the system controls whether to provide the user information corresponding to the acquisition request to the user terminal and transmits a reward to the information provider which is a transmission source of the provided user information based on factor information which affects a value of the user information stored.

Network apparatus and method for control of an electronic data exchange between provider terminal and user terminal based on factor information

An information processing system includes an acquiring unit that acquires motion information indicating a current motion of a user, a determining unit that compares the motion information acquired by the acquiring unit with standard information indicating a motion of the user in a predetermined state to determine the presence or absence of a state change of the user, and a calculating unit that, when the determining unit determines that a state change is present, calculates an area that the user visually recognizes based on sight line information concerning a sight line of the user contained in the motion information.
