Abstract: A crime type inference system based on text data, may include: a keywords dictionary construction unit configured to receive crime source data, and generate a crime type keywords dictionary by extracting crime keywords; a data set construction unit configured to generate a dataset for crime type learning by using the crime source data and the keywords dictionary; a crime type prediction model training unit configured to generate a crime type prediction model by using the dataset, and train the crime type prediction model; and a crime type inference unit configured to infer a crime type by using new crime data.

Abstract: A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.

Abstract: A network cooperation-based low power type charged broadcasting set-top box and a controlling method therefor, the set-top box sub-dividing a standby mode of the set-top box into an active standby mode, in which only background functions are processed without processing a main function, and a passive standby mode, in which no functions are processed; extending the passive standby mode occupation time to more than that of the active standby mode; and including a way of transitioning between operating modes by exchanging information regarding the set-top box through an inter-cooperation between a charged broadcasting network and the set-top box, thereby reducing the power consumption of a processor (SoC) which processes multimedia contents and minimizing the power consumption while the set-top box is in standby mode.
