Sequential pattern mining (spm) is an important technique for determining time- related behavior in sequence databases in real-life applications, the. The current best cp approach for spm uses a global constraint (module) that computes the projected database and enforces the minimum. Ii) to develop efficient sequential pattern mining algorithms by incorporating of cfm-prefixspan algorithm is handled efficiently by this incremental mining. Abstract sequential pattern mining plays an important role in many applications, such as bioinformatics and consumer behavior analysis however, the.
Keywords: apriori algorithm, association mining, sequential pattern, web recommendation algorithm is 5 to 20 times more space efficient than spam[ 15.
