Research works on structured documents only focuse a bit on the context of mobility. In such a case, we assume that the objectives of an information retrieval remain the same: we need to satisfy the user information needs. We need however to take into account the sizes of the display devices and the bandwidth of the networks used. We propose here a first attempt that considers such constraints by putting emphasize on small document parts. As for any scientific work, evaluation is a must. That is why we propose a way to include such constraints when evaluating information retrieval systems in a mobile context. The proposed measure comes from cumulated gain values, already in use for structured document retrieval, and includes the document size when computing the relevance of documents in a mobile context.
