Title: Computer Simulation of Language Acquisition:
A Proposal concerning early language learning in a micro-world

Abstract: The goal of this work is to investigate the acquisition of
particular elementary linguistic functions in a simulation
The linguistic functions are denotation of objects and spatial
relations. They are placed in the context of simulated action.
A simulated micro-world, as it is known from research in
situated action and learning (e.g. robotics), is supplemented
by linguistic explanations of a 'teacher'.
The agent has the (simulated) capability of visual perception
in a field of attention, of manipulation with physical objects,
and of generating utterances, which relate to perception and
action of the agent itself. The development of the latter
capability is the subject of the learning approaches.
The agent's utterances correspond by content to the
explanations of the teacher.
The goal of learning is to attribute certain nouns (e.g.
vase, ball, pen, corner, window, center, floor)
to objects or places, and prepositions in, at,
between) to spatial relations between them and
to correctly generate descriptions of actions or scenes.
The acquisition of denotations must be realized by a
learning method which is based on association, classification
Particular attention is placed on the emergence of a
semantic representation as a mediating level between cognitive
and linguistic structures.
The progression of language acquisition, the necessary input by
the 'teacher', the types of mistakes and incomplete productions
are compared to data from child language acquisition
which have been made available by the CHILDES project.
This is a work of basic research, which investigates the
relation of linguistic expression and cognitive representation
in its origination by the instrument of a
