Information Processing Apparatus, Information Processing Method, and Computer Program
First Claim
1. An information processing apparatus which performs a process for generating a playlist that defines a reproduction sequence of contents comprising:
- a model information holding part configured to store therein a plurality of probability models each corresponding to a time series pattern of content feature volumes, the content feature volume being feature information about a content;
a content feature extracting part configured to acquire a content feature volume corresponding to each of a plurality of contents to be reproduced;
a playlist generating part configured to compare a time series pattern of the content feature volumes extracted in the content feature extracting part corresponding to each of a plurality of permutation patterns of a reproduction sequence of contents to be reproduced with a probability model held in the model information holding part, and generates a playlist in which a reproduction sequence of contents is set in accordance with a time series pattern of content feature volumes most analogous to the probability model; and
a content reproducing part configured to reproduce contents in accordance with the playlist generated in the playlist generating part.

Abstract
An information processing apparatus performing a process for generating a playlist defining a reproduction sequence of contents includes: a model information holding part storing therein probability models corresponding to a time series pattern of content feature volumes being feature information about contents; a content feature extracting part acquiring a content feature volume corresponding to each of contents to be reproduced; a playlist generating part comparing a time series pattern of the content feature volumes extracted in the content feature extracting part corresponding to each of permutation patterns of a reproduction sequence of contents to be reproduced with a probability model held in the model information holding part, and generating a playlist in which a reproduction sequence of contents is set in accordance with a time series pattern of content feature volumes most analogous to the probability model; and a content reproducing part reproducing contents in accordance with the generated playlist.

8. An information processing method which performs a process for generating a playlist that defines a reproduction sequence of contents in an information processing apparatus, the method comprising the steps of:
-
extracting a content feature wherein a content feature extracting part acquires a content feature volume corresponding to each of a plurality of contents to be reproduced; generating a playlist wherein a playlist generating part compares a time series pattern of the content feature volumes extracted in the step of extracting a content feature corresponding to each of a plurality of permutation patterns of a reproduction sequence of contents to be reproduced with a probability model held in advance in a model information holding part, and generates a playlist in which a reproduction sequence of contents is set in accordance with a time series pattern of content feature volumes most analogous to the probability model; and reproducing contents wherein a content reproducing part reproduces contents in accordance with the playlist generated in the step of generating a playlist. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program which allows an information processing apparatus to perform a process for generating a playlist that defines a reproduction sequence of contents, the process comprising the steps of:
-
extracting a content feature wherein a content feature extracting part is allowed to acquire a content feature volume corresponding to each of a plurality of contents to be reproduced; generating a playlist wherein a playlist generating part is allowed to compare a time series pattern of the content feature volumes extracted in the step of extracting a content feature corresponding to each of a plurality of permutation patterns of a reproduction sequence of contents to be reproduced with a probability model held in advance in a model information holding part and to generate a playlist in which a reproduction sequence of contents is set in accordance with a time series pattern of content feature volumes most analogous to the probability model; and reproducing contents wherein a content reproducing part is allowed to reproduce contents in accordance with the playlist generated in the step of generating a playlist.
