ABSTRACT. With the increasing pervasiveness of the geo-positioning tech- nologies, there is an enormous amount of spatio-textual ob-.

Zhang et al. [21] study the problem of diversified spatial keyword search on road networks, aiming at maximizing a linear function that combines both criteria.

Then we develop an efficient diversified spatial keyword search algorithm by taking advantage of spatial keyword pruning and diversity pruning techniques.
