The article proposes a methodology for a thesauri quality assessment that supports decision-makers in selecting thesauri by exploiting an overall quality measure. This measure takes into account the subjective perceptions of the decision-maker according to the reuse of thesauri in a specific application context. The analytic hierarchy process methodology is adopted to capture both subjective and objective facets involved in the thesauri quality assessment, thus providing a ranking of the thesauri assessed. Our methodology is applied to a set of thesauri by using user-driven application contexts. A step-by-step explanation of how the approach supports the decision process in the creation, maintenance and exploitation of a framework of linked thesauri is provided.
