Abstract
A method includes receiving, at an analysis server from a user device, a keyword associated with content of interest. The method includes retrieving, at the analysis server from a database, searchable tag data for first searchable tags in the database. Each searchable tag of the searchable tags corresponds to a segment of stored media content. The stored media content is associated with the user device. The first searchable tags pertain to the keyword. The searchable tag data includes an initial relevancy score and a corresponding aging factor for each first searchable tag of the first searchable tags. The method also includes generating, at the analysis server, a list of media content segments based on the searchable tag data and sending the list from the analysis server to the user device. The list is ordered based on the initial relevancy scores modified by the corresponding aging factors.
