Object recognition based on human description ontology for service robots

We are developing a helper robot able to fetch objects requested by users. This robot tries to recognize objects through verbal interaction with the user concerning the objects that it cannot detect autonomously. We have shown that the system can recognize objects based on an ontology for interaction. In this paper, we extend a human description ontology to link a "human description" to "attributes of objects" for our interactive object recognition framework. We develop an interactive object recognition system based on this ontology. Experimental results confirmed that the system could efficiently recognize objects by utilizing this ontology.
