Algorithm of topology association rules used in spatial transaction mining
Gang Fang · Computer Engineering and Applications Journal · 2010
Aiming to the presented mining algorithms based on spatial transaction inefficiently extracted spatial topology association,an algorithm of spatial topology association rules mining is proposed,which is suitable for searching topology association in spatial association transverse mining.The algorithm turns spatial topology association into integer,and uses the way of value descending to form candidate frequent itemsets.The algorithm uses number operation to gain support of candidate,and uses number attribute to reduce the number of scanned spatial transaction.The algorithm is used to mine spatial topology association rules,and this experiment indicates that the algorithm is fast and efficient.
