%0 Journal Article %T Learning to Understand by Evolving Theories %A Martin E. Mueller %A Madhura D. Thosar %J Computer Science %D 2013 %I arXiv %X In this paper, we describe an approach that enables an autonomous system to infer the semantics of a command (i.e. a symbol sequence representing an action) in terms of the relations between changes in the observations and the action instances. We present a method of how to induce a theory (i.e. a semantic description) of the meaning of a command in terms of a minimal set of background knowledge. The only thing we have is a sequence of observations from which we extract what kinds of effects were caused by performing the command. This way, we yield a description of the semantics of the action and, hence, a definition. %U http://arxiv.org/abs/1307.7303v1
