A biosemiotic framework for artificial autonomous sign users

The approach presents a system theoretic framework inspired by
biosemiotics for the study of semantics in autonomous artificial sign users. The approach uses an ethological view of analysing animal-environment interaction. We first discuss semiotics with respect to the meaning of signals taken up from the environment of an autonomous agent.

We then show how semantic issues arise in a similar way when studying adaptive sign users. Anticipation and adaptation play the important role of defining purpose, which is a necessary concept in ALife semiotics.

The proposed focus on sign acts leads to a semantics in which meaning is defined as the anticipated outcome of sign-based interaction. Finally, we argue that a novel account of semantics based on indicative acts is compatible with merely indicative approaches in more conventional semiotic frameworks.
