摘要: In the United States, smartphone ownership surpassed 69.5 million in February 2011 with a large portion of those users (20%) downloading applications (apps) that enhance usability device by adding additional functionality. A percentage apps are written specifically to utilize geographical position mobile device. One prime factors developing location prediction models is use historical data train such model. With larger sets training data, algorithms become more accurate; however, can quickly downfall if GPS stream not collected or processed correctly. Inaccurate incomplete even improperly interpreted lead inability develop accurately performing algorithms. As chipsets standard ever increasing number devices, opportunity for collection increases remarkably. The goal this study build comprehensive system addresses following challenges: (1) streams manner highly usable and has reduction errors; (2) processing order prepare it make creation algorithms; (3) prediction/labeling at level they viable commercial use. This identifies key research problems toward building CaPPture (collection, processing, prediction) system.
