ABSTRACT
We investigate how to organize a large collection of geotagged photos, working with a dataset of about 35 million images collected
from Flickr.
Our approach combines content analysis based on text
tags and image data with structural analysis based on geospatial
data.
We use the spatial distribution of where people take photos
to define a relational structure between the photos that are taken at
popular places.
We then study the interplay between this structure
and the content, using classification methods for predicting such
locations from visual, textual and temporal features of the photos.
We find that visual and temporal features improve the ability to
estimate the location of a photo, compared to using just textual features.
We illustrate using these techniques to organi
