Abstract

We present a model for anchoring categorical conceptual information which originates from physical perception and the web. The model is an extension of the anchoring framework which is used to create and maintain over time semantically grounded sensor information. Using the augmented anchoring framework that employs complex symbolic knowledge from a commonsense knowledge base, we attempt to ground and integrate symbolic and perceptual data that are available on the web. We introduce conceptual anchors which are representations of general, concrete conceptual terms. We show in an example scenario how conceptual anchors can be coherently integrated with perceptual anchors and commonsense information for the acquisition of novel concepts.

Notes

  1. http://www.semantic-robot-vision-challenge.org/.

  2. We use the term concept to refer to concrete and not abstract concepts since abstract concepts have no physical referents while concrete concepts are available to the senses. Concrete concepts in turn can be either general terms referring to groups, or specific terms referring to individuals.
