A multi-layered knowledge base system and a processing method thereof are provided. In the system, semantic space learning of converting learning data into a semantic vector, which is a vector of semantic space, by learning a transformation function based on a plurality of learning data is performed. Then, relational knowledge learning of acquiring a relation between the semantic vectors by learning a relation function based on the semantic vectors obtained by the semantic space learning is performed. The acquired relation is converted into graph knowledge. The graph knowledge uses the relation as an edge and the semantic vector corresponding to the relation as a node.

Learning data, semantic space, and graph knowledge multi-layered knowledge base system and processing method thereof

A self-evolving agent-based simulation system generates model evolution strategy for applying a difference between real-data and a simulation resulting value to a simulation model, and reconstructing components included in the simulation module using the model evolution strategy to evolve the simulation model when the difference between the real-data and the simulation resulting value of the agent-based simulation model does not satisfy a value in a predetermined error range.

Self-evolving agent-based simulation system and method thereof

The preset invention is directed to a building energy management system and method, more specifically to a building energy management system and method that can quickly detect and control an abnormal situation or an emergency situation that may occur within a building.

Building energy management system and method

A smart device includes a storage unit storing identity information of a counterpart device, a sensing unit sensing an approach by the counterpart device, a control unit determining whether the counterpart device sensed by the sensing unit corresponds to the identity information stored in the storage unit, and a combining processing unit combining a resource of the counterpart device if the counterpart device is determined by the control unit to correspond to the identity information.

Smart device resource combining method and apparatus thereof

Disclosed herein are a server and method for providing collaboration service, and a sociality management server. The server includes a service provision unit and a space construction unit. The service provision unit sets up collaboration service corresponding to the results of combining functions of at least two collaboration terminals based on sociality values corresponding to the at least two collaboration terminals. The space construction unit constructs a service provision device space via which the collaboration service is to be provided. The service provision unit provides the collaboration service to the at least two collaboration terminals via the service provision device space.

Server and method for providing collaboration service, and sociality management server

Disclosed herein is an apparatus and method that enable data sharing to be performed between short-range/middle-range/long-range mobile terminals by minimizing specific intervention of a user. The apparatus includes a social relationship management unit for managing social network group information formed by a user while the user utilizes a social network service. A device recognition and authentication unit identifies a mobile terminal of another party attempting to make a connection and allocates a data communication channel for data exchange, based on device information received from the mobile terminal of the other party attempting to make a connection and the social network group information. A shared data setting unit sets data to be shared with the mobile terminal of the other party between which the data communication channel has been established. A shared data transmission unit transmits the data to be shared to the mobile terminal of the other party.

Data sharing apparatus and method

An apparatus for controlling load allocation in a cluster system includes a cluster module having a plurality of target nodes and a cluster power management module. The cluster power management module analyzes resource usage of the target nodes by monitoring the load states of the target nodes. The cluster power management module adaptively allocates loads to the target nodes based on the analyzed resource usage and N allocation thresholds settled in response to an increase of the analyzed resource usage. The cluster power management module controls the target nodes so that the power state can be changed with the adaptively allocated loads.

Method and apparatus for controlling load allocation in cluster system

A host system includes: a virtual machine migration controller for performing live-migration of a virtual machine and driving the virtual machine; and a virtual connection unit for establishing a virtual connection with a remote device server to which a device allocated to the virtual machine is connected. The host system further includes and a virtual controller for providing information for establishing the virtual connection to a destination host of the live-migration, or receiving the information for establishing the virtual connection from a source host from which the live-migration starts and providing the information to the virtual connection unit, driving the virtual machine which has live-migrated.

Host system and remote device server for maintaining virtual connectivity during live migration of virtual machine, and connectivity maintaining method using the same

There is a master server according to an embodiment of the present invention that includes: a remote USB information manager receiving information on a USB device connected to a remote USB bridge from the remote USB bridge and managing the received information; a virtual machine information manager receiving information of a user's virtual machine from a virtual machine host server and managing the received information; a user request processor, in accordance with a request of a user who wants to access a predetermined USB device on the remote USB bridge, extracting information on the corresponding USB device from the remote USB information manager and extracting the information on the user's virtual machine from the virtual machine information manager; and a remote USB connection controller connecting the user's virtual machine to the predetermined USB device by using the information extracted by the user request processor.

Remote USB system for supporting multiple virtual machines of multiple host and method thereof

Disclosed is a system for providing personalization of virtual machines for a system on demand (SoD) service includes an SoD server, wherein the SoD server includes an aspect measuring unit that measures user's use habits and aspects with respect to the peripheral devices on the basis of use or not of the peripheral devices; a preference generating unit that calculates preference for each attribute with respect to attributes included in the peripheral devices on the basis of the use habits and aspects measured by the aspect measuring unit; and a configuration unit that calculates satisfaction for each device with respect to peripheral devices which can be used in the virtual machine on the basis of the preference for each attribute calculated by the preference generating unit and configures the peripheral devices of the virtual machine on the basis of the calculated satisfaction for each device.
