Proximity-based method for determining concept relevance within a domain ontology

摘要

Embodiments are directed towards providing a device and method of identifying media items from a media library maintained by a media server that are similar to a designated media item. The media server stores a controlled vocabulary which is represented as a hierarchically linked set of nodes wherein a plurality of nodes correspond to concepts and a library of media items. Each media item corresponds to a record in the media library and the record includes at least one metadata field with assigned keywords. The media server receives a designation of a media item from a user computer, retrieves the keywords assigned to the media item, obtains all related concepts from the controlled vocabulary, computes a search weight for each related concept, and queries the media library to identify media items that match the designated media item and provides the results to the user computer.
