摘要:
The present invention relates to a processing method of data stream using Border Monitoring Query, and more particularly a monitoring method and a system for data streams which are a large volume of data and continuously generated such as financial ticker, GPS data or a ubiquitous sensor network (USN).The objectives of the present invention are to process a large number of BMQs over data streams in high-performance and scalable manner. For this purpose, the invention presents BMQ-Index, a scalable and high performance data stream monitoring framework. The main idea of BMQ-Index is shared and incremental processing. For shared processing, BMQ-Index adopts a query indexing approach, thereby achieving a high level of scalability. Once BMQ-Index is built on registered queries, only relevant queries are quickly searched for upon an incoming data. For incremental processing, BMQ-Index employs an incremental access method, i.e., an index structure to store delta query information and an incremental search algorithm. Thus, successive BMQ evaluations are greatly accelerated.

An exercise game system of the present invention includes a plurality of game clients and a game server. The game clients transmit over a network, exercise intensity information in which exercise intensities of the players performing various types of exercises are measured. The game server drives an exercise game by receiving exercise intensity information of the respective players from the game clients over the network, and by determining a motion of a game object to be displayed on a game screen based on exercise intensity information that is balanced according to a predetermined balancing rule about at least one element of exercise intensity, a change rate, and a duration time according to different types of exercises. In this instance, the game screen is represented to be capable of recognizing the motion of the game object that is affected by adjusting the intensity of exercise performed by the players.

A mobile apparatus includes a processing planner and a plan processor. The processing planner generates a plurality of resource use plans in response to a context monitoring query (CMQ) of an application, and selects a final plan satisfying a request of the CMQ among the resource use plans. The plan processor executes the final plan. Accordingly, the mobile apparatus may support resource-efficient context monitoring.

The present invention relates to an aspect-level news browsing service system and method for mitigating effects of media bias, which group news articles having different aspects on the same event on the basis of aspects, and simultaneously provide grouped news articles to users. The aspect-level news browsing service system may include a user terminal for accessing a news service server over an Internet and receiving aspect-level news article information from the news service server. A news provision server may transmit news article information to the news service server over the Internet. The news service server may extract aspects from the received news article information, classify the news article information based on the extracted aspects, and may transmit the aspect-level news article information to the user terminal depending on the aspects to enable the news article information to be displayed. The Internet may be configured to connect the user terminal to the news service server.

摘要:
Methods and systems of processing a data stream are disclosed. A developer may develop a service only by programming a Service Unit (SU) including a service logic (SL) and including a Service Unit Description Language (SUDL) file, so that the developer may not need to program complicated stream processing code, such as stream source connection code, network input/output (I/O) code, and buffering code. In addition, the stream source connected dynamically to the service and a service execution mode (such as push and pull modes) may be converted by simply changing setting files based on the service model. The system includes modules for managing and processing the stream in reality, such as stream source connection modules, network I/O processing modules, and stream buffering modules, the modules operating the developed program through the service model.

Disclosed herein is mobile middleware, a context monitoring method, a context-aware system, and a context-aware service provision method, which support energy-efficient context monitoring. The mobile middleware receives a request for a CMQ from context-aware application programs, receives sensor data from sensors, monitors whether the CMQ is satisfied, and transmits an event to the context-aware application programs according to results of the monitoring. In this case, the mobile middleware controls the sensors so that only sensor data required to determine whether the CMQ is satisfied needs to be transmitted so as to reduce energy consumption during the performance of the monitoring. Therefore, the mobile middleware can perform energy-efficient context monitoring, required by the context-aware application programs.
