Abstract: A method of providing a program is provided. The method includes: receiving a query of a user; semantically analyzing the query of the user; determining an intent of the user using an intent graph; recommending at least one service based on the determined intent; mashing up a selected at least one service in response to a service being selected with respect to the recommended at least one service; and providing a program generated by a result of the mashing up.

Abstract: Provided is a method and apparatus for automatically creating a service flow. A goal may be identified based on a keyword input from a user. The identified goal may be decomposed into at least one sub-goal, and a service may be discovered and determined with respect to each sub-goal. A service flow may be created based on the determined service, and a code may be generated based on the service flow.

Abstract: Provided are a service recommending apparatus and method. The service recommending method uses situation information, such as location information of a terminal possessed by a user and a user profile, to deduce the user's activity, predicts a service that is expected to be preferred by the user according to the user's situation, and provides the result of the prediction to the user. The location information of the terminal is acquired from a network server such as a location information server through an open API gateway.

Abstract: Provided are a system and method for providing an electronic business card service using an open service interface.

Abstract: An IPTV supplementary service control system and an IPTV supplementary service method using the system are provided. The IPTV supplementary service control system decrypts an IPTV supplementary service request contained in an SOAP message contained in a set-top box in order to provide the IPTV supplementary service. The IPTV supplementary service control system generates a control command required to perform the requested IPTV supplementary service and transmits the control command to a head end which transmits a content via a multicast network. Accordingly, it is possible to easily generate and provide the IPTV supplementary service by remotely controlling the head end.

Abstract: Provided are a main-memory resident object-relational database management system (ORDBMS) and a method of deleting a class instance using the ORDBMS. The method includes obtaining a mutual exclusive lock for a class to be deleted as per the query and a child class inheriting from the class when a query of deleting an instance is input from a database access application program, and deleting the instance from the class and at least one instance related to the instance from its child class using OID reference.
