Abstract:
An ontology-based knowledge modeling system comprising: a conceptual modeling (100) unit for classifying a knowledge region of a specific domain, performing detailed modeling on a conceptual detailed domain within the classified knowledge region, and configuring a specific domain knowledge model (110) having the respective detailed models (120) as a set; a logical modeling (200) unit for configuring a schema-based logical model (210) based on respective detailed schemas (220) defined by referring to detailed models that correspond to the detailed schemas one by one from the set of the specific domain knowledge model of the conceptual modeling unit; and a physical modeling (300) unit for configuring a physical knowledge reposit model (310) by a detailed data repository (320) for physically analyzing the schemas defined by respective detailed schemas in the logical modeling process, and a mediator (340) for controlling an external interface (330) of the detailed data repository.
Abstract:
An apparatus and method for context awareness by detecting intentions of a user in the ubiquitous environment using context information which is created by analyzing real world data collected from sensors are provided. The apparatus is configured of a sensor platform, a context-aware agent and a service provider. The sensor platform collects data of real world and transmits the collected data to the context-aware agent. The context-aware agent integrates the data of real world from the sensor platform, and stores and manages context information according to the integrated data. The service provider automatically controls objects to perform necessary operations to provide a predetermined intelligent services according to the context information received from the context-aware agent.
