摘要:
The present invention relates to a method for generating a decision tree using an inference engine in a ubiquitous environment. In the method, a data table for a data event set is generated based on information collected by at least one sensor. Subsequently, a weight value of the data event set is established, and an entropy is calculated based on the established weight value (here, the entropy is a scale for classifying the information collected by the sensor into respective classes). In addition, the decision tree for the collected information is formed based on the calculated entropy.

The present invention relates to a method for establishing a connection between heterogeneous user-networks and a domain name system proxy server for controlling the same. The present invention has features of providing a method for supporting communication between user-computers included in Internet-compatible heterogeneous networks through a gateway based on an Internet public network and a domain name system proxy server for controlling the method. According to the present invention, supporting mutual communication between various networks based on one network can be expected.

Provided is a polarization division multiplexed optical transmission system including a transmitter and a receiver. The transmitter includes a first light source generating an optical signal having a linear polarization state; a second light source generating an optical signal having a horizontal polarization state; a first signal generator receiving a first data stream to modulate the optical signal output from the first light source using an M method; a second signal generator receiving a second data stream to modulate the optical signal output from the second light source using an N method; and a polarization beam combiner (PBC) multiplexing the optical signals that were modulated using the M and N methods while maintaining the linear and horizontal polarization states.

A dynamic service combination system and service provision method using user's context information are provided. a service may be dynamically provided and a new service may be combined to be provided to a service user using the user's context information. In addition, a new ontology may be configured by finding a new knowledge through AI engine's data mining, and thus a success rate of the service provision may be increased, and a dynamic service provision may be achieved.

A user and service mobility support system and method of in a ubiquitous environment is provided. When a user moves to a domain area capable of using various service equipment by pursuing a location of a user using a mobile communication service outdoors, the user may continuously use a service by determining service equipment based on the user's preference information, available equipment information, and service characteristic information. The user may continuously use a service through various equipments although the user moves into the domain area while the user has used a mobile communication service through the terminal outdoors. In order to select service equipment from among various media equipment, the optimum service equipment is determined based on the user and service characteristic information, and accordingly, it is possible to provide service movement convenience and satisfaction to the user.

摘要:
A context information management system provides service mobility that allows user to maintain service even while moving the service environment. That is, when user service environment movement is sensed, user service provided in previous service environment is consecutively provided to the user in the new service environment using the service context information of user service provided in the previous service environment. In such a manner, the service user may continuously use a same service that used in the previous service environment although the user moves to other service environments without a service terminal.
