Location-Based Services for Surrounding Area with Myanmar Language on Mobile Devices.

Location-based services provide the users who are not familiar with the region to find their desired location. There has been developed for many location-based services on the mobile devices but the location-based services with Myanmar native are still poor. The pronunciation error is still occurred in existing application and it is still necessary to develop the efficient and effective one. Spatial index can be used to quickly retrieve the geo-information efficiently and effectively. One of the problems in the mobile devices is spatial index because of the limited memory and low computation capacity. A new index structure is proposed to retrieve the desired location based information for user’s surrounding area by using Myanmar language on the mobile devices. The proposed index structure is constructed by using Hilbert space filling curve and B-tree that combines the inverted file to reduce the searching time. Myanmar 3 is used as the Myanmar keyword in this paper to avoid the various sequence order of the character because the typing order of Myanmar language may be various form.
