We present a novel framework for querying multi-modal data from a heterogeneous database containing images, textual tags, and GPS coordinates. We construct a bi-layer graph structure using localized image-parts and associated GPS locations and textual tags from the database. The first layer graphs capture similar data points from a single modality using a spectral clustering algorithm. The second layer of our multi-modal network allows one to integrate the relationships between clusters of different modalities. The proposed network model enables us to use flexible multi-modal queries on the database.
