Most existing closed sequential patterns mining algorithms have not considered the user's participation. In order to accomplish the interaction of user in mining process, a Closed Sequential Patterns mining based on Regular Expression constraints called RE-CSP is presented for mining closed sequential patterns based on regular expression constraints. RE-CSP only scans sequence database once, uses the technique of memory index to mine closed sequential patterns. Firstly, the index set for each frequent 1-sequence is constructed in memory. Stems are found in the data sequences indicated by the index set.
