A Social Image Retrieval Result Diversification Dataset
This dataset is designed to support research in the areas of information retrieval that foster new technologies for improving both the relevance and the diversification of search results with explicit focus on the social media context. The dataset consists of Creative Commons data related to 396 landmark locations and contains 43,418 Flickr photos together with their Wikipedia and Flickr metadata and some content descriptor information (visual and text). Data is annotated for the relevance and the diversity of the photos (both expert and crowd annotations are provided).
The dataset was validated during the 2013 Retrieving Diverse Social Images Task at the MediaEval Benchmarking Initiative for Multimedia Evaluation.
