    摘要: A communication network system includes a resource network element and further includes a resource server adapted to retrieve availability information of the resource network element and to allocate the resource network element according to the retrieved availability information. A service processing method in a communication network at the resource server side includes: receiving a resource query request; and searching for an available resource network element and responding with it being a response result. A service processing method in a communication network at the resource network element side includes: receiving a request for a service; determining whether the service can be processed immediately, and if not, transmitting a resource query request to a resource server; and transmitting the service request to an available resource network element in a response result. A resource server and a resource network element are further disclosed. With a resource server, the invention can monitor dynamically availability information of a resource network element and allocate appropriately an idle resource network element to thereby improve both a utilization ratio of network resource and a service processing capability of network element.

    摘要: The present invention proposes a temporally-controlled item recommendation method and system based on rating prediction. According to this invention, the item recommendation method comprises inputting an item to be recommended; determining a temporal rating model related to the item, the temporal rating model being used to predict variation of the rating of the item with time; applying one or more recommendation strategies to the determined temporal rating model to determine optimal recommendation times of the item; and recommending the item to a user at the determined optimal recommendation times. In different embodiments, the temporal rating model of the item can be selected from a set of pre-stored temporal rating models or automatically generated according to history data in the system. In addition, the selected temporal rating model can be adjusted in accordance with user preference information or user feedback information. The item recommendation system of this invention is able to consider the change of a user's interest in a given item with time so as to increase the effectiveness of recommendations and improve user experience.
