A context aware service provision method and apparatus for recognizing the user context and executing an action corresponding to the user context according to a rule defined by the user and feeding back the execution result to the user interactively are provided. The method for providing a context-aware service includes receiving a user input, the user input being at least one of a text input and a speech input, identifying a rule including a condition and an action corresponding to the condition based on the received user input, activating the rule to detect a context which corresponds to the condition of the rule, and executing, when the context is detected, the action corresponding to the condition.

A context-aware service recommender system receives current user context and recommends a list of browser-based services to a user on a mobile devices. A user's mobile device receives context events from smart environments in which the mobile device is operating. Data about the context events is relayed to a service recommendation server. The server develops recommendations based on the context and other factors, and relays information about the recommended services to the mobile device. As each recommended service is selected or ignored by the user of the mobile device, the device sends implicit feedback with this information to the service recommendation server for use in subsequent recommendations.

An apparatus and method for providing a context-aware service are provided. The apparatus includes a context-aware service object (CAS) management module managing information on a CAS and a context defined by the CAS, a sensor management module managing information on a sensor and requesting the sensor to observe knowledge, and a context management module informing the CAS management module of a CAS defining a context provided by the CAS management module when observed knowledge satisfies the context defined by the CAS, wherein upon being informed of the CAS by the context management module, the CAS management module requests the CAS to provide a service.

The disclosure is directed to modifying the operation of one or more hardware subsystems when a new context awareness service begins. An aspect determines a power budget for a plurality of operating context awareness services including the new context awareness service, wherein the power budget is based on a power requirement for each of the plurality of context awareness services, and wherein the power requirement for each of the plurality of context awareness services is based on power utilizations of the one or more hardware subsystems corresponding to the plurality of context awareness services, and allocates power resources to the one or more hardware subsystems based on importances of the plurality of context awareness services and/or the one or more hardware subsystems, wherein the allocation of the power resources is performed within the power budget.

A method for providing context-based services is disclosed, including: receiving, by a service platform, a notification from a first device, the notification including information of a context obtained about a user by the first device; and transmitting, by the service platform, the information of the context to at least one second device such that the at least one second device is triggered to execute a pre-configured service command corresponding to the information of the context, the at least one second device being correlated to the information of the context.

The invention provides a polling method of a low-power consumption sensor used for a context-aware application program on the basis of context-aware service of the sensor in a smartphone. By using the method, unnecessary sensor activities can be dynamically removed, so that the sensors can be kept in a sleep state for a long time. Additionally, the invention also provides a method for searching the relation between an application request and the sensor activities. By adopting the method, multiple application program combination detecting frequencies which are invoked by a user are calculated and matched by a polling scheduler, so as to lead low-power consumption polling to avoid unnecessary activities. When different context application programs are used for evaluating the method, results indicate that the low-power consumption polling response time in a middleware is minimum (97ms). Compared with that of the traditional exhaustive polling operation, the energy consumption can be saved by about 70%. Through the context-aware service, the energy consumption of the sensor of the smartphone can be reduced, and the service life of a battery of the smartphone is prolonged.

Context-aware system, method, and computer-readable recording medium for providing an intelligent service in an Internet of Things (IoT) environment are provided. The context-aware system includes a plurality of IoT devices, each including at least one sensor and a communication unit, a gateway connected to the plurality of IoT devices and including at least one gateway device connected to an Internet network, and a cloud server layer which transmits and receives data to and from the plurality of IoT devices through the Internet network and the gateway, wherein at least one IoT device, which cannot perform a context-aware processing process in real time, generates context information, and transmits it to a context-aware server of the cloud server layer. The context-aware server performs the context-aware processing process of the IoT device to generate context-aware result information, and transmits the result information back to the IoT device.

The present invention relates to a system configuration and an apparatus for preventing the infringement of user privacy, and for collecting and analyzing information regardless of the service feature and type, while a system providing a context aware service collects and analyzes user information. The present invention discloses a method of configuring and using a context analyzer and a device profile database in order for the system providing the context aware service to collect and analyze information regardless of the service feature and type.

Aimed at the problem that a traditional semantic net body and a context sensing system are not suitable for processing dynamic knowledge in the real world, a context sensing system driven by a pragmatic web on the basis of the advantages of the pragmatic web in expressing the dynamic knowledge is invented. According to the context sensing system driven by the pragmatic web, a context sensing system framework driven by the pragmatic web is developed, an efficient and novel context acquisition technology is adopted, the true intention of a user can be more accurately captured, and on this basis, a high-level context with a decision-making capability is obtained through inference, and finally a 'user-centered' personalized recommendation service is achieved through a context sensing service discovery method based on an intelligent agent.

The invention discloses a perception system and method providing an intelligent service in an internet of things. The perception system comprises multiple internet of things devices, a gateway deviceand a cloud server layer. It is determined that at least one internet of things device generates information, wherein the context information is a base component of a context perception processing process; the generated context information is sent to a context perception server of the cloud server layer; the perception server conducts the context perception processing process of the internet of things device, sends the context information so as to generate context perception result information which is to be used as result data, sends the generated context perception result information again to the context information sent by the internet of things device, and gives a support so as to enable the internet of things device receiving the context perception result information to perform at least one operation corresponding to received context perception result information.
