English abstract:
This paper is concerned with potential recall in multimodal information retrieval in graph-based models. We provide a framework to leverage individuality and combination of features of different modalities through our formulation of faceted search. We employ a potential recall analysis on a test collection to gain insight on the corpus and further highlight the role of multiple facets, relations between the objects, and semantic links in recall improvement. We conduct the experiments on a multimodal dataset containing approximately 400,000 documents and images. We demonstrate that leveraging multiple facets increases most notably the recall for very hard topics by up to 316%.
