Geo-temporal distribution of tag terms for event-related image retrieval
We have developed a new approach that effectively retrieves event-based images. We have proposed a rigorous technique to extract spatial features from image tags. We have developed a method for summarizing spatial distributions of single tags. We have developed new techniques for spatial relatedness between two tag terms. Our spatio-temporal IR method improves the retrieval performance significantly.
