Tag information management apparatus, tag information management system,content data management program, and tag information management method

A content data management system that manages tag information indicating attributes relating to content data, comprising:

• an extraction section that extracts positional information indicating geographic positions associated with the content data and time information indicating time points associated with the content data, the positional information and the time information being attached to the content data;
• a speed computation section that computes speeds associated with the content data, based on the positional information and the time information extracted by the extraction section;
• and
• a grouping section that groups the content data, based on the speeds computed by the speed computation section.

A non-transitory computer readable medium that stores a computer program for managing tag information indicating attributes relating to content data, the computer program causing a computer to execute the steps of:

• extracting positional information indicating geographic positions associated with the content data and time information indicating time points associated with the content data, the positional information and the time information being attached to the content data;
• computing speeds associated with the content data, based on the extracted positional information and the extracted time information;
• and
• grouping the content data, based on the computed speeds.
