With the recent increase in both volume and diversity of multimedia data, effective browsing and retrieval methods become more and more important in order to deal with the available data and find the relevant documents. While this problem is well understood for textual documents, where an information need can often be expressed in sufficient detail with a textual query, the effective search in multimedia documents is generally more difficult.

The 2nd International Workshop on Interactive Multimedia Retrieval calls for submissions related to interactive retrieval in and across all types of multimedia content. We invite submissions reporting on current work done in the context of e.g., the Video Browser Showdown or the Lifelog Search Challenge as well as interactive variants of solutions to TRECVID, MediaEval or similar tasks, describing methods, but also insights and lessons learned from participating in such benchmarks. In this context, contributions related (but not limited) to the following topics are invited:

*interactive retrieval approaches and methods
*browsing and interactive search user interfaces
*multi-user search, retrieval, and browsing
*understanding user behavior and information needs
*cross/multi-modal retrieval methods
*datasets, evaluation metrics, and protocols
*multimedia indexing methods
*video/audio summarization methods
*interactive multimedia system design and architecture


The relation of the paper to an interactive search process (rather than being designed for a fully automatic one) will be a key selection criterion for the workshop.

Papers for oral and poster presentations shall be submitted as 6 to 8-page papers using the ACM proceedings format and need not be anonymized (i.e. we use single-blind review). Selected papers will be presented in an oral or poster presentation. All presenters are encouraged to also demonstrate their interactive retrieval solutions in a dedicated demo session.
