Real users, however, often begin an interaction with a search engine with a su ciently under-speci ed information need that they will need to reformulate before they nd either the one thing or every thing they are looking for. We de ne a session as the sequence of queries and interactions that a user performs in service of an information need. The rst workshop on Information Retrieval Over Query Sessions was held at ECIR 2011 in Dublin, Ireland, with the purpose of investigating questions of measuring, analyzing, and optimizing IR system behavior over a session of reformulations. Introduction The idea of supporting information retrieval (IR) over user sessions has not received as much attention in IR as one might expect, despite the interactive and dynamic nature of real life searching. However, the growing interest in Interactive IR (IIR), coupled
