Adaptivity in IR interactions requires the IR systems adapting to users' situations and the users adapting to the systems. System adaption entails dynamic user modeling, effective information architecture and enhanced search features such as search integration and relevance feedback; user adaptation through interactions entails mental model building and modification towards a coherent state of knowledge and learning.
The panel is structured as follows. Initially we provide an overview of the panel contents, consisting of four central dimensions of adaptivity in IR interaction. These are adaption 1) through integration of information objects; 2) of information system to searcher; 3) of searcher to information system; and 4) to context and practice. The sequence follows the order of the panellists, i.e., each panellist is the prime mover of a particular dimension.
