Context-Driven Image Annotation Using Imagenet, George E. Noel, Gilbert L. Peterson
Context-Driven Image Annotation Using Imagenet, George E. Noel, Gilbert L. Peterson
Faculty Publications
Image annotation research has demonstrated success on test data for focused domains. Unfortunately, extending these techniques to the broader topics found in real world data often results in poor performance. This paper proposes a novel approach that leverages WordNet and ImageNet capabilities to annotate images based on local text and image features. Signatures generated from ImageNet images based on WordNet synonymous sets are compared using Earth Mover's Distance against the query image and used to rank order surrounding words by relevancy. The results demonstrate effective image annotation, producing higher accuracy and improved specificity over the ALIPR image annotation system. Abstract …
Automated Agent Ontology Creation For Distributed Databases, Austin A. Bartolo
Automated Agent Ontology Creation For Distributed Databases, Austin A. Bartolo
Theses and Dissertations
In distributed database environments, the combination of resources from multiple sources requiring different interfaces is a universal problem. The current solution requires an expert to generate an ontology, or mapping, which contains all interconnections between the various fields in the databases. This research proposes the application of software agents in automating the ontology creation for distributed database environments with minimal communication. The automatic creation of a domain ontology alleviates the need for experts to manually map one database to other databases in the environment. Using several combined comparison methods, these agents communicate and negotiate similarities between information sources and retain …
