I2RS: A Distributed Geo-Textual Image Retrieval and Recommendation System
Summary: I2RS is a distributed geo-textual image retrieval and recommendation system that uses SPB-trees to index geo-tagged images. It supports metric similarity queries (top-m spatio-temporal range, kNN), offers interactive recommendations, and scales to 100M images in a browser-server deployment.
