Aiming at redundancy computing problem of spatial association rule mining algorithm,this paper proposes a spatial association rule mining algorithm based on numerical index,which is suitable for mining monolayer transverse spatial association rules.It uses ordering to generate numerical index in the course of bottom-up and top-down search,and uses numerical index to prune repeated candidate and delete redundancy computing in the course of double mining,so that the efficiency of the algorithm is improved.Experimental result indicates that the algorithm is more efficient and effective than other algorithms.
