SYSTEM AND METHOD FOR MINING PLAYLIST DATA FOR USE IN PROVIDING DIGITAL MEDIA OR OTHER CONTENT

In accordance with an embodiment, described herein is a system and method for mining playlist data, for use in providing advertisement-supported media content or targeted advertisements. A media server provides media content items as one or more media streams. Each of a plurality of playlists is associated with theme words provided by a title and/or description of the playlist. A playlist can also be associated with one or more theme words associated with the at least one media content item included in the playlist based on inclusion of the at least one media content item in the playlist. A dataset of media content item-theme word pairs provides an association of a particular media content item included in a particular playlist, with a theme word associated with that playlist. A score is assigned to each of the media content item-theme word pairs based on their appearances across several playlists. Advertisement-supported media content or targeted advertisements can be selected based on the dataset of media content item-theme word pairs, and, for example, fetched from an advertisement server, for insertion into a media stream.
