Development of Syntactic and Semantic Structure in Artificial Agents

Development of syntax and semantics of language is studied with a constructive approach in a network model of agents. Agents with generative grammar systems evolve through communication in terms of their own grammar in a language game. They form a community sharing usages of symbols and develop to equip recursive structures. After development, agents become to have double articulation mechanism in their grammar. Semantics is expressed by word-space which is a space to represent interrelationship among words. The relationship is formed according to ways of usage of language and calculated by means of mutual dependency between words and sentences. An agent can develop categorization in its word-space from sentences.
