Abstract: Provided are a data processing device and a data processing method that allow selecting and performing of an appropriate operation according to user's emotions. A user's face is detected and features of the user's face are extracted from data on the detected face. The user's emotions are estimated from the extracted facial features, and data based on the estimated user's emotions is generated. Whether the generated data is transmitted to an external device is determined on the basis of positional data of the user and the external device including a data reception unit, which is included in a radio wave transmitted from the Global Positioning System. When it is determined that the generated data is transmitted, it is transmitted to the external device. The external device that has received the data selects and executes operation based on the received data.

Abstract: A data processing system that can sense fatigue or the like using a neural network is provided. First, a reference image is obtained on the basis of first to n-th images (n is an integer greater than or equal to 2). Next, the first to n-th images and the reference image are input to an input layer of a neural network, first to n-th estimated ages and a reference estimated age are output from an output layer, and first to n-th data and reference data are output from an intermediate layer. After that, first to n-th coordinates are obtained in each of which an x-coordinate is a value corresponding to a difference between the reference estimated age and the first to n-th estimated ages and a y-coordinate is a value corresponding to the degree of similarity between the reference data and the first to n-th data. Next, a query image is input to the input layer, a query estimated age is output from the output layer, query data is output from the intermediate layer, and query coordinates are obtained using the output results. Whether a person of a face included in the query image feels fatigue or the like is determined on the basis of the first to n-th coordinates and the query coordinates.

Abstract: A similar document is retrieved in units of blocks of a document. Highly accurate document search is performed. A specific text block is searched for in a plurality of text blocks created by dividing each of a plurality of search target documents. A first search text block, which is a part of a search document, is prepared; full-text search is performed by using at least some of the plurality of text blocks as a first target and using the first search text block as a search criterion to calculate first relevance of each text block included in the first target to the first search text block; a second target is determined from the first target depending on a level of the first relevance; first similarities of each sentence included in the first search text block to sentences included in the second target are calculated; and at least one text block similar to the first search text block is retrieved using the first similarities.
