OntoGen extension for exploring image collections
OntoGen is a semi-automatic and data-driven ontol- ogy editor focusing on editing of topic ontologies. It utilizes text mining tools to make the ontology-related tasks simpler to the user. This focus on building ontologies from textual data is what we are trying to bridge. We have successfully extended OntoGen to work with image data and allow for ontology construction and editing on collections of labeled or unlabeled images. Browsing large heterogenous image collections efficiently is certainly a challenging task - and we feel that semiautomatic ontology construction, as described in this paper, makes this task easier.
