Patent ID: 8468229

Claim:
A method implemented by a control system for controlling distribution of media contents over a network of an operator, wherein said contents comprise distributed contents to surrogate servers and remaining contents that have not been distributed to the surrogate servers, comprising the steps of: identifying, by the operator, additional contents that are not distributed over the network yet; dynamically retrieving a set of semantics from the distributed contents as a set of categories; automatically identifying, for each category, at least a reference content by analyzing meta data of the media contents, wherein said identifying comprises identifying a set of reference contents by using search engines and calculating a central reference content of said set of reference contents; associating, by the control system, said identified contents with said predefined categories based on semantics affinity with said reference content, said semantics affinity being calculated as the distance of each of said identified contents to said reference content, wherein said calculating comprises using data mining or artificial intelligence mechanisms; determining, by the control system, an interest value for each category based on statistical data indicative of user interest in the distributed contents associated with the respective category; receiving an input of a first interest threshold and a second interest threshold greater than the first interest threshold; identifying, by the control system, at least one first category and at least one second category, from said set of categories, when the distributed contents associated with the first category have an interest value below the first interest threshold and the distributed contents associated with the second category have an interest value that exceeds the second interest threshold; removing the distributed contents associated with the first category from the surrogate servers; and making at least one of the identified contents associated with said second category available for distribution at the surrogate servers.
