Abstract

Human, syntactic language is one of the most intriguing behaviors and receives increasing attention from researchers in numerous fields. Here we present a model that goes an important step further than previous work because it explicitly connects low-level perception and categorization, hierarchical meaning construction and syntactic language. The model thus shows a solution to the ‘symbol grounding problem’ (Harnad, 1990): the meaning of the symbolic system – logical symbols and syntactic rules – is grounded in its relation with a simplified but realistic world. We discuss the different components of this collaborative effort: (i) a realistic simulation of Newtonian dynamics of objects in a 2D plane; (ii) schemabased event-perception and categorization; (iii) a semantics based on predicate logic; and (iv) a categorial grammar for the production and interpretation of language. The integration of the different components poses on the one hand novel and important constraints; on the other hand, it allows for experiments that help to identify the relations between the different levels. We note some important similarities and differences with SHRDLU (Winograd, 1976) and the Talking Heads experiment (Steels et al., 2002), and give an agenda for future experiments.
