No single mechanism can be expected to give optimal retrieval in all cases in information retrieval (IR) in context. Many problems have been reported concerning the difficulty of making the right choices at the design stage of information retrieval systems. This paper presents a flexible model of information retrieval process together with a mechanism exploiting query typologies for instantiating the flexible model. The proposed model integrated in a single framework various alternative information retrieval primitives. This is possible thanks to attaching to every primitive strategic parameters which express different alternatives. We show how the parametized model can be combined with a Case-Based Reasoning (CBR) appraoch to incrementaly improve an information retrieval strategy.
