MEDIA CONTENT ORDERING SYSTEM AND METHOD FOR ORDERING MEDIA CONTENT

摘要

The present invention relates to a media content ordering system and to a method for ordering media content. According to the invention, media content items are ordered in two different spaces, i.e. metadata space and feature space. This allows a user to select and retrieve desired content more easily. Media content that is clustered in either space represents similar media content. Suggestions can be made to the user taking into account the preferences of the user with respect to features and metadata particulars. By minimizing the difference in order in both spaces, it is ensured that suggestions to a user are close both in feature space and metadata space.

1. A media content ordering system configured to order content in a content database that holds a plurality of media content items, wherein each media content item is associated with metadata describing that media content item, the system comprising:
a feature analyzer device comprising a plurality of different feature analyzers that are each configured to perform feature analysis regarding a different feature on each of the media content items comprised in the content database, each feature analyzer outputting a feature vector that describes a presence of the feature in the media content item; a metadata ordering device for ordering the media content items in an ordered metadata space based on the associated metadata; a weighting unit for applying a weighting using weighting coefficients to the outputted feature vectors; a feature vector ordering unit for ordering the weighted outputted feature vectors in an ordered feature vector space; wherein the weighting unit is configured to change the weighting coefficients such that a difference between the order of the media content items in the ordered feature space and the order of the media content items in the ordered metadata space is minimized.
