Disclosed herein is a method for parallel mining of temporal relations in a large event file using a MapReduce model. In the method for parallel mining of temporal relations in a large even file according to the present invention, an event file is sorted based on customer identification (ID) and event time at which each event has occurred. A set of large event types satisfying a preset support or more is generated from the event file. The event file is converted into a large event sequence including the large event type set. The large event sequence is summarized and then a time interval data file is created. Candidate temporal relations are generated from the time interval data file, and frequent temporal relations satisfying a preset support or more are derived from the candidate temporal relations. A temporal relation rule is generated from the derived frequent temporal relations.

An apparatus for managing a plurality of wireless sensor networks selects a configuring policy according to a characteristic of each wireless sensor network and configures a network with the selected configuring policy for management. When an error occurs in the wireless sensor network, the apparatus performs error diagnosis based on a configuring policy applied to the error-detected wireless sensor network, infers a cause of the error, and provides an error recovery method corresponding to the inferred cause of the error to the error-detected wireless sensor network.

Apparatus and method for managing wireless sensor network

Provided are a Ubiquitous Sensor Network (USN) middleware apparatus and method for generating an information service based on heterogeneous sensor networks and a system for providing the information service using the same. In the system, a sensor node constructing a sensor network senses environment information, and a sensor network data transmitter collects sensed data sensed by the sensor node in real-time and transmits the collected sensed data in a message form. A USN middleware extracts object and environment information by cleaning, classifying and integrating the message received from the sensor network data transmitter, generates conditional events and context aware information from the extracted object and environment information, and provides the information service to an application program, the application program providing a user with information related to environment where the sensor network observes.

Provided is a real-time business process triggering system (RBPTS) using a Radio Frequency Identification (RFID) and a method thereof. The RBPTS is to provides interface to a corporation information system by generating an RFID event proper to a specific domain by giving the RFID data a business meaning to apply the RFID data to a predetermined rule before transmitting the RFID data to the corporation information system, provide a rule modeling function to flexibly managing changes in application field and environment, and provide an RFID related-action related to rule performance, and a method thereof. The RBPTS includes: an RFID middleware adapter for receiving RFID data from an RFID middleware/RFID reader and generating RFID events Extensible Markup Language (XML) document; an event manager for receiving the RFID events XML document from the RFID middleware adapter and generating an event query for inference; a rule manager for generating a result set by performing rule inference on the event query through an inference engine and generating an action list; Web Service arbitrator for communicating through Web Service using an external application and a Simple Object Access Protocol (SOAP); an action manager for performing real-time action by calling the Web Service through the Web Service arbitrator based on the action list; and an event repository for storing and managing registered all RFID event information, rule and action. The RBPTS is applied to maritime freight transportation.

Real-time business process triggering system and method using RFID

Provided is a mobile Radio Frequency Identification (RFID) service providing apparatus and a method thereof. The apparatus, includes: a policy server for establishing a policy on level of quality of service (QoS) to be provided to each user, and a policy to be applied between nodes for security; an Authentication, Authorization and Accounting (AAA) server for performing network access authentication and authorization to each user, authorization for a mobile RFID service, security association establishment and distribution between constituent nodes based on information of the policy server; a mobile RFID agent for performing a diameter client role and a mobile RFID service agent role; and a service server for searching uniform resource locator (URL) of a server providing information related to an RFID code and providing detailed information and history information to the mobile RFID phone.
