Abstract	Collaborative image tagging systems, such as Flickr, are very attractive for supporting keyword-based image retrieval, but some user-provided tags of collaboratively-tagged social images might be imprecise. Some people may use general or high-level words (i.e., abstract tags) to tag their images for saving time and effort, but such general or high-level tags are too abstract to describe the visual content of social images precisely. As a result, users may not be able to find what they need when they use the specific keywords for query specification. To tackle the problem of abstract tags, an ontology with three-level semantics is constructed for detecting the candidates of abstract tags from large-scale social images. Then the image context (nearest neighbors) and tag context (most relevant tags) of social images with abstract tags are used to ultimately confirm whether these candidates are abstract or not and identify the specific tags which can further depict the images with abstract tags. In addition, all the relevant tags, which correspond with intermediate nodes between the abstract tags and specific tags on our concept ontology, are added to enrich the tags of social images so that users can have more choices to select various keywords for query specification. We have tested our proposed algorithms on two types of data sets (revised standard datasets and self-constructed dataset) and compared our approach with other approaches.
