Social event detection and retrieval in collaborative photo collections

In this paper, we present an approach to detect social events and retrieve associated photos in collaboratively annotated photo collections. We combine data of various modalities such as time, location, and textual and visual features within a framework that has a classification model at its core. Compared to traditional approaches that mainly consider the photos only as a source of information, we also incorporate external information from datasets and online web services to further improve the performance. Experiments based on the MediaEval Social Event Detection Dataset demonstrate the effectiveness of our approach.
