Knowledge Representation and Reasoning for Perceptual Anchoring

Jonas Melchert, Silvia Coradeschi, Amy Loutfi
2007 19th IEEE International Conference on Tools with Artificial Intelligence(ICTAI 2007)  
In this work we report results on the use of symbolic knowledge representation and reasoning (KRR) for perceptual anchoring.  ...  This is the creation and maintenance of a connection between symbolic and perceptual description that refer to the same physical object in the environment.  ...  We decided to solve this with a handcrafted rule Assert-Smells-Of (in Loom): Whenever a Smells-Of assertion is added to the A-Box of the KB, the method Assert-Contains-Liquid-Has-Smell asserts that the  ...
