One of the most utilized concepts in CHIIR research is 'information need', which has been used as part of research designs in both qualitative and quantitative studies, either as an integral element of experiments and evaluations or as an explanatory aspect of information searching. Its definitions and operationalizations are likewise many and they often remain vague hindering the possibility to credibly compare findings. This tutorial will help participants to use the concept more precisely and appropriately in their own research. The tutorial consists of talks by experienced researchers combined with small group and plenary sessions.
