Adding Semantic Modules to improve Goal-Oriented Analysis of Data Warehouses using I-star

Requirements elicitation and analysis is a key step in designing and maintaining data warehouses. In order to better support this step, in this paper we (i) propose an extension of the basic goaloriented metamodel in order to include semantic modules, (ii) include a description of each step followed in the process, and (iii) evaluate it by means of an empirical experiment.
