User terminal and content searching and presentation method
First Claim
1. In a terminal of an original user comprising a processor and memory storing a playlist and a list of owned content, a content searching method comprising steps, executed by the processor, of:
- accessing a playlist of a different user from the terminal and obtaining the playlist of the different user;
computing a similarity between the obtained playlist of the different user and the playlist of the original user in accordance with a predetermined computation equation, wherein content of the playlist of the original user is part of content stored in the memory, wherein the similarity is based on a number of items common to both the playlist of the original user and the playlist of the different user and on a size of the playlist of the original user and a size of the playlist of the different user, and wherein commonality between a first item from the playlist of the original user and a second item from the playlist of the different user is determined based at least in part on a sale source and bibliographical information for the first item and the second item;
identifying, as a searched result, at least one item that is contained in the playlist of the different user and that is not contained in the playlist of the original user when the computed similarity exceeds a predetermined threshold value;
determining whether the list of owned content stored in the memory of the terminal of the original user includes the at least one item, wherein the list of owned content is owned by the original user;
when it is determined that the list of owned content includes the at least one item, adding the at least one item to the playlist of the original user; and
when it is determined that the list of owned content does not include the at least one item, adding the at least one item to a recommendation list.
