Abstract: The present disclosure herein relates to an interaction device capable of performing an interaction with a human, and more particularly, to an interaction device capable of performing an interaction with a plurality of participants. The interaction device includes a role classifying unit configured to classify a role for each of a plurality of participants based on an external stimulus signal for each of the plurality of participants and an action adjusting unit configured to perform different interaction operations for each of the plurality of participants based on the role for each of the plurality of participants. An interaction device according to an embodiment of the present application classifies the roles of a plurality of participants according to a participation degree and/or an action state and provides a customized interaction operation for each of participants according to the classified roles. Therefore, it is possible to perform a natural interaction operation with a plurality of participants.

Abstract: A method of modeling a radio wave environment, the method being executed by a radio wave environment modeling apparatus using a group of intelligent robots includes measuring an intensity of radio waves received from at least one follower robot; measuring a distance between the at least one follower robot and a leader robot that belongs to the group of intelligent robots; and estimating an environment parameter using a wave model. Further, the method includes classifying the environment parameter estimated from at least one lattice by comparing the estimated environment parameter with predetermined environment parameters; and analogizing an intensity of radio waves of the at least one follower robot that are received from the at least one lattice.

Abstract: An apparatus for providing a service application using a robot includes a sensing unit configured to generate environmental sensing information on the surrounding of a moving path of the robot and user state information; and a user circumstance determination unit configured to determine the circumstance and intention of a user to generate user recognition information, and searches and downloads a service application. Further, the apparatus includes a service provision unit configured to search service representation devices around the moving path of the robot and migrate a service corresponding to the service application to at least one of the searched service representation devices; and a user feedback management unit configured to manage feedback information corresponding to an interaction between the user and the robot.

Abstract: Provided is a path-token-based web service caching method including determining whether or not stored cache data exists when a web service call request exists, and when the cache data does not exist, creating a predetermined path-token set and a predetermined tag data set based on a message schema of Web Services Description Language (WSDL), and creating a request Simple Object Access Protocol (SOAP) message, creating a request SOAP message template by using a path-token for the created request SOAP message, and calling the web service, and creating cache data including the tag data set, input values set, the request SOAP message template, the request SOAP message, and SOAP binding information. Accordingly, the method can solve the problems of a conventional web service caching method whereby the method can not cope with change in the number of inputs, and an exact input position is not searched for when an input value is changed.

Abstract: A system and method for aborting web services automatically. An application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator sends a command to compensate a second sub-transaction already committed. A protocol service unit transmits and receives messages for managing the first sub-transaction. A registration service unit registers the generated first sub-transaction with the global transaction coordinator.

Abstract: A system for aborting web services automatically and a method thereof are provided. In the system, an application program container has a first web service application program embedded, intercepts a message that is transmitted and received between a second web service program located externally and the first web service application program, identifies the kind of an operation requested by the second web service application program, and keeps information required for compensation. A protocol manager generates and manages a first sub-transaction object by a request of the second web service application program. A local compensator compensates the first sub-transaction if a global transaction coordinator that coordinates the state and success factor of a global transaction which is an upper-layer transaction of the generated first sub-transaction sends a command to compensate a second sub-transaction already committed.
