Abstract

An information processing apparatus is disclosed. The information processing apparatus includes: an identifying means for identifying a group to which a content belongs from predetermined groups based on metadata describing descriptions of a content; and a clustering means for clustering a first set that is a set of the contents whose belonging group is not identified and classifying the first set into a cluster based on the metadata.

Claims

1. An information processing apparatus comprising:

an identifying means for identifying a group to which a content belongs from predetermined groups based on metadata describing descriptions of a content; and

a clustering means for clustering a first set that is a set of the contents whose belonging group is not identified and classifying the first set into a cluster based on the metadata.

2. The information processing apparatus according to claim 1,

wherein the clustering means clusters a second set that is a set of the contents belonging to the selected group or the cluster to classify the second set into a cluster.

3. The information processing apparatus according to claim 1, further comprising a retrieving means for retrieving a related content that is the content relating to the content that is a base point for retrieval based on the metadata,

wherein the identifying means identifying the group to which the related content belongs.

4. The information processing apparatus according to claim 1, further comprising a presentation control means for controlling the presentation of the contents so that the contents are classified and presented by each of the groups and the clusters.

5. An information processing method comprising the steps of:

identifying a group to which a content belongs from predetermined groups based on metadata describing descriptions of a content; and

clustering a set of the contents whose belonging group is not identified and classifying the set into a cluster based on the metadata.

6. A program which allows a computer to execute a process comprising the steps of:

identifying a group to which a content belongs from predetermined groups based on metadata describing descriptions of a content; and

clustering a set of the contents whose belonging group is not identified and classifying the set into a cluster based on the metadata.

7. An information processing apparatus comprising:

an identifying unit which identifies a group to which a content belongs from predetermined groups based on metadata describing descriptions of a content; and

a clustering unit which clusters a first set that is a set of the contents whose belonging group is not identified and classifies the first set into a cluster based on the metadata.
