ImageCLEF 2009 - Photo Retrieval Task

Website: http://www.imageclef.org/2009/Photo Twitter: http://www.twitter.com/ImageCLEFPhoto

The photo retrieval task of ImageCLEF 2009 is intended to provide a further study in the importance of diversity in image search result.

Diversity is highly needed when users put poorly specified or ambiguous queries. Since search engine knows nothing about users' preference of relevant images, search engine could increase probability of finding relevant images by presenting different images which cover all possible representations within the query. Duplicate images should be reduced, as they are not considered useful by users. Diversity is also needed when users put same queries, but require different sets of results. These reasons are evidences of the importance of diversity, and image search engine should be able to tackle these problems by presenting a diverse result. This task requires participants to analyse the best way to improve diversity while still presenting images with high relevance.
