Issues Search: WordNet patterns that increase recall without sacrificing precision (Hollink) Issues w.r.t. thesauri Use case: find images with the same subject Issues Conceptual subject descriptions Example concepts in image Use of conceptual categories by people searching for images Thesauri for scenes: Iconclass Annotation of image content Some forms of image content are well suited to image analysis The semantic gap Example semantic bridge: microscopic cell images Segmentation often requires user interaction Automatic detection of concepts can be difficult even in 'easy' cases Image analysis useful for collection navigation Bridging the semantic gap: CBIR and ontologies Sample visual features and their mapping to WordNet Experiment: pruning the search for 'conveyance' concepts Bridging the semantic gap: concept detectors 'Concepts' for which visual detectors were built LSCOM lexicon: 229 - Weather LSCOM lexicon: 110 - Female Anchor 'Concepts' for which visual detectors were built Natural-lang proc.
