Disclosed are a method and a system for adding annotations into an input medium file. The method comprises a step of creating annotation detection models based on training samples formed by existing media files having annotations; a step of extracting coexistence coefficients of any two annotations based on appearance frequencies of the annotations in the training samples; a step of inputting the input medium file; a step of extracting sense-of-vision features from the input medium file; a step of obtaining initial annotations of the input medium file; a step of acquiring candidate annotations based on the initial annotations and the coexistence coefficients of the annotations in the training samples; and a step of selecting a final annotation set from the candidate annotations based on the sense-of-vision features of the input medium file and the coexistence coefficients by using the annotation detection models.

Annotation addition method, annotation addition system using the same, and machine-readable medium

When encoding each element in numeral string data, a code-string data creating unit creates code string data by assigning a code to a focused element to be encoded based on a magnitude relation between the focused element and an element adjacent to the focused element. An control unit stores primary data and the code string data as registration information in an associated manner into a storage unit. When searching for the primary data, a data extracting unit and the code-string data creating unit create code string data from image data, and a searching unit searches data stored in the storage unit based on the created code string data as search information for data having registration information that matches the search information.

Information processing apparatus, information processing method, and computer product

System, method, and computer-readable medium for seeking representative images in an image set. Text features of each of the plural images are extracted. Diversity data of the image set is obtained based on the text features. A representative score of each of the plural images is calculated based on the diversity data. One or more of the images in the image set is selected as a representative image based on the representative score of the corresponding images.
