Patent Document ID: 9232205
Application ID: 13814181

Base Claim:
1. An information processing device, comprising: a learning module configured to extract an image feature amount of each frame of an image of learning content and extracting word frequency information regarding a frequency of appearance of each word in a description text describing a content of the image of the learning content as a text feature amount of the description text, wherein the learning content includes a text of a caption, and wherein the description text is the text of the caption included in the learning content, and learn an annotation model, which is a multi-stream HMM (Hidden Markov Model), by using an annotation sequence for annotation, which is a multi-stream including the image feature amount and the text feature amount; and a browsing controller configured to extract a scene, which is a group of one or more temporally continuous frames, from target content from which the scene is to be extracted by using the annotation model, and display representative images of scenes so as to be arranged in chronological order.

Claim 2:
2. The information processing device according to claim 1 , wherein the learning means extracts words included in the text of the caption displayed in a window as one document while shifting the window of a predetermined time length at regular intervals, and extracts multinomial distribution, which represents a frequency of appearance of each word in the document, as the text feature amount.
