Abstract This paper describes a population of communicating agents, rewarded for successful dialogs. Agents encode and decode messages about their environment using the TAG formalism. Experimental results show that lexical and word order conventions spread under suitable con­ ditions.
1. Introduction Modeling language development and use in a group of communicating synthetic agents may bring new in­ sights to some problems of natural language processing. Such models have been proposed by MacLennan [1] [2] and by Dyer [3], using elementary, automata­like agents to study evolution of a common lexicon. Steels [4] ad­ vocates use of physical robots, and convincingly grounds lexicon and even grammatical categories in the agents' perception and categorization of the real world. Hashimoto and Ikegami [5] focus on emergent syntax from a formal point of view. In this paper, we study emergence of words and of word order conventions among agents. We use a simpli­ fied version of the Tree Adjoining Grammar [6], in which derivation trees represent configurations of the environment (ß2), commented upon by the agents (ß3.1). Dialogs allow the linguistic conventions to spread (ß3.2) as shown by experimental results (ß4). 2. The Environment Configurations of the environment are randomly generated by the control program. They consist in a logical form description of a block world made of ob­ jects (cubes, spheres, cylinders) with various character­ istics (red, big, heavy), and involved in positional rela­ tions (on, in front of, left of) and comparison relations (greater, taller, heavier). We take advantage of the TAG formalism to describe situations in terms of derivation trees (DT), which account for semantic dependencies in a phrase. Here, they represent entities and their ...
