Special Session at CBMI 2023

Despite the advances in automated content description using deep learning, and the emergence of joint image-text embedding models, many video retrieval tasks still require a human user in the loop. This is in particular the case when the information need is fuzzy, or when the underlying dataset is homogeneous, i.e. contains data from one domain, differing in small details and with little or no editorial structure. Interactive video retrieval (IVR) systems address these challenges. In order to assess their performance, multimedia retrieval benchmarks such as Video Browser Showdown (VBS) or Lifelog Search Challenge (LSC) have been established. These benchmarks provide large-scale datasets as well as task settings and evaluation protocols, allowing to measure progress in research on IVR systems. However, in order to achieve the best possible performance of the participating systems, they are usually operated by members of the development team. This setting does not allow to pro!
 perly measure usability aspects of the system, which are important in order to deploy them successfully in a target application context, where they need to be operated by domain experts rather than video retrieval researchers.

This special session thus aims at providing better insights into how such systems are usable by users with solid IT background, but not familiar with the details behind the system. The special session thus calls for papers describing IVR systems, addressing topics such as

– search functionalities supporting non-expert users
– browsing and navigation capabilities
– approaches to result visualisation
– usability aspects of the system

The contributions to this session are short papers (4 pages + references), describing the participating IVR system. In contrast to papers such as submitted to VBS or LSC, these papers should focus on how the system supports users that are not retrieval experts, and the search and browsing features expected to be of particular interest to these users.

The review process is single-blind. A link to a three-minute video showcasing the usage of the system on the VBS collection must be included with the submission. Prior participation on VBS is not a prerequisite for submission.

The IVR systems will be presented in the demo session, followed by an interactive competition session, in which the systems are used by novice users to solve video retrieval tasks.
