Information processing apparatus, information processing method and program

Abstract

The present invention relates to an information processing apparatus, an information processing method and an information processing program that are capable of assigning an optimum keyword to a content. The information processing apparatus includes a content characteristic quantity extraction unit 52, a label information extraction unit 54, a associating information computation unit 56, a content characteristic quantity—latent space associating information storage unit 57 and a label information—latent space associating information storage unit 58. The content characteristic quantity extraction unit 52 extracts characteristic quantities related to a content whereas the label information extraction unit 54 extracts label information showing attributes of a content. The associating information computation unit 56 computes parameters representing the property of a probability distribution for a latent variable Zk common to the characteristic quantities and the label information, the property of a probability distribution for the characteristic quantities and the property of a probability distribution for label information. By storing computed values for the latent variable zk in the content characteristic quantity—latent space associating information storage unit 57 and the label information—latent space associating information storage unit 58, the information processing apparatus is capable of assigning an optimum keyword to a content. The present invention can be applied to the information processing apparatus.
