Abstract
A method and an apparatus for generating an explanation for a recommendation based on the content of a recommended multimedia content item and a multimedia content item forming the basis for the recommendation are described. Concepts associated to the recommended multimedia content item are compared with vertices of a directed graph to associate the recommended item to a first vertex of the directed graph. The vertices of the directed graph represent concepts derived from one or more knowledge bases. Then a multimedia content item that has been previously accessed by the user is selected. Concepts associated to this previously accessed multimedia content item are compared with vertices of the directed graph to associate the previously accessed multimedia content item to a second vertex of the directed graph. Subsequently a path between the first vertex of the directed graph and the second vertex of the directed graph is determined using edges of the directed graph. Finally, the determined path is provided to the user as an explanation for the recommendation.
