Abstract: Provided are a method and apparatus for providing a location-based service (LBS) in a dynamic road network, which include, according to an LBS request signal received from at least one user terminal, generating a query object based on location information of the user terminal; searching for at least one data object located within a threshold radius based on the user terminal; generating a cluster including at least one query object based on at least one node; comparing distances between boundary query objects and an inner query object based on the generated cluster and calculating a nearest neighbor for each query object; and identifying the data object associated with the calculated nearest neighbor.

Abstract: Provided is a method and system for preventing transfer errors of big data, including dividing entire data to be transmitted by a first device into a plurality of pieces of entity data and allocating a resource to first entity data among the plurality of pieces of entity data, applying, by the first device, the first entity data to a filter to query for the first entity data, transmitting, by the first device, the first entity data to a second device based on a result of the query for the first entity data, and upon receiving a sync request for the first entity data from the second device, releasing, by the first device, the resource allocated to the first entity data.
