Information processing apparatus, sameness determination system, sameness determination method, and computer program

An information processing apparatus comprising:

• one or more processors and/or circuits in the information processing apparatus, wherein the one or more processors and/or circuits are operable to:
• separate first subtitle information included in first content from the first content;
• extract a first subtitle feature quantity representing a feature of the first content on the basis of the separated first subtitle information;
• and
• transmit comment information to an information providing server different from the information processing apparatus providing a user's comment associated with the first content on a network, wherein the comment information is generated by attaching the extracted first subtitle feature quantity to the user's comment, wherein the information providing server collates the first subtitle feature quantity received from the information processing apparatus and a second subtitle feature quantity associated with a second content.

A sameness determination system for determining a sameness of a content, the sameness determination system comprising:

• an information processing apparatus for inputting a user's comment on first content;
• and
• an information providing server different from the information processing apparatus for providing, on a network, the user's comment received from the information processing apparatus,
• wherein the information processing apparatus comprises a first set of one or more processors and/or circuits operable to:
• separate first subtitle information included in the first content from the first content;
• extract a first subtitle feature quantity representing a feature of the first content on the basis of the separated first subtitle information;
• input the user's comment made on the first content;
• and
• transmit comment information to the information providing server providing the user's comment on the network, wherein the comment information is generated by attaching the extracted first subtitle feature quantity to the user's comment made on the first content, and
• the information providing server comprises a second set of one or more processors and/or circuits operable to:
• extract a second subtitle feature quantity representing a feature of second content from second subtitle information included in the second content;
• associate and store identification information to identify the second content and the second subtitle feature quantity extracted from the second content;
• collate the second subtitle feature quantity and the first subtitle feature quantity included in the comment information received from the information processing apparatus;
• determine sameness between the second subtitle feature quantity and the first subtitle feature quantity in the comment information based on the collation;
• and
• output a result based on the determined sameness.

A sameness determination method comprising:

• inputting a user's comment made on first content to separate first subtitle information included in the first content from the first content received by an information processing apparatus;
• extracting a first subtitle feature quantity representing a feature of the first content on the basis of the first subtitle information;
• and
• transmitting comment information to an information providing server different from the information processing apparatus providing the user's comment on a network, wherein the comment information is made by attaching the first subtitle feature quantity to the user's comment made on the first content, wherein the information providing server:
• extracts a second subtitle feature quantity representing a feature of second content from second subtitle information included in the second content;
• associates and stores identification information to identify the second content and the second subtitle feature quantity extracted from the second content;
• collates the second subtitle feature quantity and the first subtitle feature quantity included in the comment information received from the information processing apparatus;
• determines sameness between the second subtitle feature quantity and the first subtitle feature quantity in the comment information based on the collation;
• and
• outputs a collation result based on the determined sameness.

A non-transitory computer readable storage medium having stored thereon, a computer program having at least one code section executable by a computer, thereby causing the computer to perform the steps comprising:

• in an information providing server:
• extracting a first subtitle feature quantity representing a feature of first content from first subtitle information included in the first content;
• associating and storing identification information to identify the first content and the first subtitle feature quantity extracted from the first content;
• receiving comment information, from an information processing apparatus different from the information providing server, providing a user's comment on second content, wherein the information processing apparatus generates the comment information by attaching a second subtitle feature quantity corresponding to the second content to the user's comment;
• collating the stored first subtitle feature quantity and the second subtitle feature quantity included in the comment information received from the information processing apparatus;
• determining sameness between the first content corresponding to the stored first subtitle feature quantity and the second content corresponding to the second subtitle feature quantity based on the collation;
• and
• outputting a result based on the determined sameness.
