Ontogator: Combining View-And Ontology-Based Search With Semantic Browsing
The authors show how the benefits of the view-based search method, developed within the information retrieval community, can be combined and extended with the benefits of ontology-based annotations and search, developed within the Semantic Web community. As a proof of the concept, they have implemented an ontology- and view-based image retrieval and recommendation browser Ontogator. Ontogator is innovative in two ways. Firstly, the RDFS-based ontologies used for annotating image metadata are used in the end user interface to facilitate view-based image retrieval. The views provide the user with a search function and means for getting useful overviews of the contents in the repository. Secondly, a semantic browsing function is provided by a recommender system.
