1. A method of annotating an image comprising:

  • extracting and indexing both visual features and textual information from a plurality of images and a two step probabilistic modeling technique comprising identifying words from the textual information as candidate annotations and annotating the image with the candidate annotations that have the highest average conditional probabilities;

    hashing the plurality of visual features;

    clustering the plurality of images based at least in part on hash values derived from the hashing, the clustering creating clustered images;

    building one or more statistical language models based at least in part on the visual features and the textual information of the clustered images; and

    annotating the image using one or more of the statistical language models.
