 note = {A nearest neighbor query is an important notion inspatial databases and moving object databases. In the emergingapplication fields of moving object technologies, such as mobilesensors and mobile robotics, the location of an object is oftenimprecise due to noise and estimation errors. We proposetechniques for processing a nearest neighbor query when thelocation of the query object is specified by an imprecise Gaussiandistribution. First, we consider two query processing strategiesfor pruning candidate objects, which can reduce the numberof objects that require numerical integration for computing thequalification probabilities. In addition, we consider a hybridapproach that combines the two strategies. The performance ofthe proposed methods is evaluated using test data.},
