A device for distributing a load and managing power of a virtual server cluster includes a monitoring unit configured to monitor a load distribution condition on server nodes included in a server cluster and a dynamic state of each of the server nodes, a server node information storage unit configured to store static state information of each of the server nodes, a policy determination unit configured to determine a load distribution policy and a power management policy for each of the server nodes using monitoring information and the static state information stored in the server node information storage unit, and a controller configured to control conversion of each of the server nodes into an active state or an inactive state according to the power management policy, and distribution of a load of a service request requested by a service client to activated server nodes according to the load distribution policy.

Device for distributing load and managing power of virtual server cluster and method thereof

Provided is a question answering system with respect to a natural language question and a method thereof. The question answering system includes a candidate answer generating unit configured to extract a document mapped to an input natural language question, and generate candidate answers with respect to the natural language question from the extracted document, a text entailment recognizing unit configured to generate a text entailment recognition result representing a degree of association between multiple evidence sentences including the generated candidate answers and the natural language question, a list generating unit configured to generate a candidate answer list including the multiple evidence sentences in high association degree order on the basis of the text entailment recognition result, and an output unit configured to output the generated candidate answer list as a search result with respect to the natural language question.

Question answering system and method

Disclosed are a smart learning system using a device social relation and a method thereof. The smart learning system includes a first device that generates a device social relation and shares learning content, and at least one second device that executes an event related to the learning content by acquiring the shared learning content when is included in the device social relation.

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.

Disclosed are an apparatus for collecting lifelog data and a method thereof according to the present invention. The present invention relates to an apparatus for collecting lifelog data and a method thereof, which collect information for analyzing a behavior pattern from devices used by a user in everyday life, convert the collected information according to a preset schema, and provide the converted information.

Apparatus for collecting lifelog data and method thereof

A system and method for data matching are disclosed. A user terminal included in the system includes a data provider, a data consumer, and a mapper. The data provider receives life log data of a user which is collected by at least one life log collecting apparatus. The data consumer receives the life log data from the data provider, and compares the life log data and reference data received from a service server to determine whether a difference between the life log data and the reference data exceeds a predetermined threshold value. The mapper maps the service server which provides the reference data corresponding to information of the life log data received from the data provider. Accordingly, the usability to of life log apparatuses can increase.

System and method for data matching

Provided are a headset for a user specific audio service and a method for a user specific audio service using the same. The headset for a user specific audio service includes: a sensing unit sensing whether or not the headset is put on; an information collecting unit determining whether or not the headset is put on by the sensing unit and collecting current situation information of a user when the headset is put on; and an information processing unit generating a user profile based on the current situation information of the user, and controlling an audio signal output of a digital audio device based on the generated user profile.

Provided are a pointing apparatus capable of providing haptic feedback, and a haptic interaction system and method using the same. The pointing apparatus includes a wireless communication unit, a controller, and a haptic stimulator. The wireless communication unit receives an event including haptic output information through wireless communication with the outside. The controller generates a control signal for reproducing a haptic pattern corresponding to the haptic output information. The haptic stimulator reproduces the haptic pattern by means of the control signal. Thus, it is possible to increase the performance and usability of a user interface of a user terminal including a touch screen.

Disclosed herein is a method for emotion recognition based on a minimum classification error. In the method, a speaker's neutral emotion is extracted using a Gaussian mixture model (GMM), other emotions except the neutral emotion are classified using the Gaussian Mixture Model to which a discriminative weight for minimizing the loss function of a classification error for the feature vector for emotion recognition is applied. In the emotion recognition, the emotion recognition is performed by applying a discriminative weight evaluated using the Gaussian Mixture Model based on minimum classification error to feature vectors of the emotion classified with difficult, thereby enhancing the performance of emotion recognition.
