%A Paul Vogt %J Robotics and Autonomous Systems %T Anchoring of semiotic symbols %X This paper presents arguments for approaching the anchoring problem using {\em semiotic symbols}. Semiotic symbols are defined by a triadic relation between forms, meanings and referents, thus having an implicit relation to the real world.Anchors are formed between these three elements rather than between `traditional' symbols and sensory images. This allows an optimization between the form (i.e. the `traditional' symbol) and the referent. A robotic experiment based on adaptive language games illustrates how the anchoring of semiotic symbols can be achieved in a bottom-up fashion. The paper concludes that applying semiotic symbols is a potentially valuable approach toward anchoring. %N 2 %K symbol grounding problem, anchoring problem, language evolution %P 109-120 %E A.
