The groupization aims to enrich the individual preferences using similar individual's data. It may efficiently adapt the query results to the user expectations. In this paper, we aim to optimally identify the analyst' groups in a data warehouse. For that reason, we study the similarity between the selected queries in the analytical history. To enhance the quality of derived groups of analysts, we introduce a new method of semi-supervised hierarchical clustering under constraints ranking for handling cases when some constraints are more important than others and must be firstly enforced during the groupization process. Four axis for group identification are distinguished: (i)聽the function exerted, (ii)聽the granted responsibilities to accomplish goals, (iii)聽the source of groups identification, (iv)聽the dynamicity of discovered groups. Carried out experiments on real log files used for decision-maker groupization in data warehouse confirm the soundness of our approach. Our findings demonstrate that groupization improves upon personalization for several group types, mainly for function-based groupization and explicitly identified groups.
