Imcube @ MediaEval 2015 Retrieving Diverse Social Images Task: Multimodal Filtering and Re-ranking.

This paper summarizes the participation of Imcube at the Retrieving Diverse Social Images Task of MediaEval 2015. This task addresses the problem of result diversification in the context of social photo retrieval where the results of a query should contain relevant but diverse items. Therefore, we propose a multi-modal approach for filtering and re-ranking in order to improve the relevancy and diversity of the returned list of ranked images.
