Integrating quantitative attributes in hierarchical clustering of transactional data

Appropriate data mining exploration methods can reveal valuable but hidden information in today's large quantities of transac- tional data. While association rules generation is commonly used for transactional data analysis, clustering is rather rarely used for analysis of this type of data. In this paper we provide adaptations of parameters related to association rules generation so they can be used to represent distance. Furthermore, we integrate goal-oriented quantitative attributes in distance measure formulation to increase the quality of gained results and streamline the decision making process. As a proof of concept, newly developed measures are tested and results are discussed both on a refer- ent dataset as well as a large real-life retail dataset.
