Mining hybrid sequential patterns and sequential rules

摘要

The problem addressed in this paper is to discover the frequently occurred sequential patterns from databases. Basically, the existing studies on finding sequential patterns can be roughly classified into two main categories. In the First category, the discovered patterns are continuous patterns, where all the elements in the pattern appear in Consecutive positions in transactions. The second category is to mine discontinuous patterns, where the adjacent Elements in the pattern need not appear consecutively in transactions. Although there are many researches on finding Either kind of patterns, no previous researches can find both of them.
