In this paper we presented a framework for the query refinement which is driven by the user's information needs. Based on the analyses of the real IR case studies we gathered the requirements and modeled the query refinement process as the process of changing query ambiguity according to a user s need. We define several semantic and structural ambiguities, implied by the used vocabulary and information repository, respectively. As our evaluation study shows, the usability of the approach overcomes the traditional information retrieval problems and enables the realisation of an e-shop-assistant in the e-commerce applications.
