“…In [16] the authors demonstrate object-based video retrieval on a single movie Groundhog Day, where shots are retrieved based on objects appearing within the film, other common objects specified by example images and different visual aspects of the same object. In [17] the authors demonstrate shot retrieval based on segmented query objects matching segmented movie objects using colour, shape and/or texture. Shot retrieval based on the whole frame is also supported.…”

“…Another retrieval system based on a visual-query is described in [4], where the query is initialised by the user by one or more images which can come from outside the system (e.g., from Google Image search). The user can then select objects inside the image, or specify which is the feature (colour or texture) or visual-characteristic that makes it a good query image.…”

Abstract-How to efficiently browse a large video database if its content is unknown to the user? In this paper we propose new approaches for browsing initialisation, exploration and content access of a rushes archive, where the span of information stored can be huge and difficult to understand at a glance. Exploring and navigating through raw footage is assisted by organising the video material in a meaningful structure and by adopting appropriate visualisation solutions. Un-annotated content is organised in hierarchical previews, while browsing is enabled by novel methods of random exploration and random content access to preview nodes. User tests conducted on professional users in a realwork scenario aim at demonstrating how the hierarchical visualisation and the proposed random browsing solutions assist the process of accessing and retrieving desired content.

“…In the most of the cases two interface conditions are compared to test which one works best. There is no constraint to reality: the system can effectively retrieve (Sav et al 2006) or be just a simulation (Dumais et al 2001); the user interface can support the accomplishment of a task (McDonald and Tait 2003) or just collect user's answers (e.g. relevance judgement) (Oard et al 2004).…”

On the role of user-centred evaluation in the advancement of interactive information retrieval

This paper discusses the role of user-centred evaluations as an essential method for researching interactive information retrieval. It draws mainly on the work carried out during the Clarity Project where different user-centred evaluations were used during the lifecycle of a cross-language information retrieval system. The iterative testing was not only instrumental to the development of a usable system, but it enhanced our knowledge of the potential, impact, and actual use of cross-language information retrieval technology. Indeed the role of the user evaluation was dual: by testing a specific prototype it was possible to gain a micro-view and assess the effectiveness of each component of the complex system; by cumulating the result of all the evaluations (in total 43 people were involved) it was possible to build a macro-view of how cross-language retrieval would impact on users and their tasks. By showing the richness of results that can be acquired, this paper aims at stimulating researchers into considering user-centred evaluations as a flexible, adaptable and comprehensive technique for investigating non-traditional information access systems.
