An Improved Definition of Multidimensional Inter-transaction Association Rule

Association rule is an important contribution to the data mining field from the database research community, and its mining has become a promising research topic. Traditional association rule is limited to intra-transaction mining. Recently the concept of multidimensional inter-transaction association rule (MDITAR) is proposed by H.J. Lu. Based on analysis of inadequencies of Lu’s definition, this paper introduces a modified and extended definition of MDITAR, which consequently makes MDITAR more general, practical and reasonable.
