Abstract: Disclosed herein are an apparatus and method for a multi-cloud service platform. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program may receive a service request from a user client device, generate a multi-cloud infrastructure service using multiple clouds in response to the service request, make the multiple clouds interoperate with mufti-cloud infrastructure in order to provide the multi-cloud infrastructure service, and generate a multi-cloud application runtime environment corresponding to the multi-cloud infrastructure service.

Abstract: Disclosed is a composite for forming a coacervate interfacial film. The composite for forming the coacervate interfacial film contains a cationic hectorite nanoplate-shaped particle structure containing a hectorite nanoplate-shaped particle and a cationic surfactant coupled to a surface of the hectorite nanoplate-shaped particle, and an anionic cellulose nanofibril containing an anionic functional group in at least a portion thereof, in which the composite may form the coacervate interfacial film at an interface of an oil phase and a water phase through electrostatic interaction between the cationic surfactant and the anionic functional group.

Abstract: An artificial intelligence (AI) based method for controlling a multimedia device according to an embodiment of the present disclosure makes it possible to ensure accuracy in detection and interpretation of a voice command of a user by enabling an AI care device to control the volume of the multimedia device by itself or allow the user to control the volume of the multimedia device by transmitting voice guidance for volume control to the user when the AI care device does not accurately detect the voice signal of the user due to the audio signal of the multimedia device and the voice signal of the user applied to the AI care device at the same time.

Abstract: A knowledge representation expansion apparatus includes: a predicate-argument structure analyzing unit for extracting a predicate and at least one argument from a text using a meaning representation language; an ontology unit for representing knowledge using a knowledge representation language, which is a structured format understandable by a computer, and for extracting a second predicate corresponding to a first predicate, which is extracted from the predicate-argument structure analyzing unit; and a knowledge representation unit for representing knowledge extracted from the text using the first predicate, when the similarity of the first predicate and the second predicate is equal to or less than a threshold value.

Abstract: Provided is a medical service satisfaction rank information providing system that computes and provides quantified statistical rank information according to a medical institution/department/doctor upon a user request based on medical service satisfaction points inputted by a user that received a medical service and recommendation points for each medical institution/department/doctor inputted by a service information provider, and a method thereof. The method for providing medical service satisfaction information includes the steps of: a) receiving a medical service satisfaction point and storing the medical service satisfaction point; b) receiving a recommendation point and storing the recommendation point; and c) computing rank information by using the medical service satisfaction point and the recommendation point, and providing the rank information to the user terminal.
