Abstract: The present disclosure pertains to recommendation of playlists having data elements on visual maps to a user. The proposed method comprises receiving a search query comprising a data element; retrieving attributes associated with the data element; mapping the data element on pre-set visual maps that overlap with the data element and/or with the associated attributes; assigning weight to each mapped pre-set visual map based on extent of contextual overlap between the search query and the respective pre-set visual map; and recommending the mapped pre-set visual maps based on weight associated with each of the retrieved pre-set visual maps, each recommended map comprising one or more data elements, at least a set of which data elements being logically connected to form the recommended playlist for the user based on user profile, said set of selected data elements being connected so as to form a trajectory to be presented as the playlist.

Abstract: A user-friendly graphical user interface is proposed to enable creation of a playlist of data elements of any type. A graphical object is displayed representing a content based logical map arranged in two or three dimensions and defining characteristics at predefined coordinates. A trajectory defined by a mathematical spline function and having a start point, an end point and one or more intermediate points is drawn and can be changed by moving the steering point of at least one of the start point and the end point. The data elements for the playlist are selected by searching in meta-data for characteristics that best match the characteristics of points along the trajectory.

Abstract: The invention enables music tracks in a playlist to be explored using a unique music genogram data format. The invention further enables a user to map an emotional trajectory on the emotion wheel as a basis for the generation of the playlist with music tracks. The invention provides for a unique visualization of the playlist using the emotional wheel representation. A user will be given the option to specify an initial mood and a destination mood. The trajectory between the initial mood and the destination mood may be steered through the emotions falling in-between. The thus obtained mood trajectory is then populated by music tracks to form a playlist.
