information system engineering to represent cultural heritage domain concepts. Evaluations of the modelling techniques were performed by carrying out experiments with cultural heritage specialists. The first experiment consisted in evaluating UML class diagrams and a conceptual graph. The second experiment evaluated a value cluster modelling approach. These qualitative evaluations were conducted using focus groups composed of cultural heritage specialists. We evaluated the perceived ease of use, the perceived usefulness and the intention to use of the three techniques (UML class diagrams, conceptual graphs and the value cluster approach). Thanks to these evaluations, we will be able to propose a combined approach using value cluster modelling and UML class diagramming techniques to describe cultural heritage information
