Effect of dialogue strategies on concept acquisition made with interactions among infant agents

摘要

This paper described concept acquisition through the interaction between an infant agent and a mother (human) and the interaction among infant agents (IAs). At the first stage, three mothers teach concepts to each IA by pointing an object on a screen and speaking an attribute of the object. The attribute includes color, figure, location, and operation to an object. At the second stage, IAs interact each other and share the concepts. Effective interaction needs sophisticated dialogue strategies, such as how to ask and how to answer. We investigated two types of experiments, the first concept learning assigns a supervisor to an IA and the second one does not assign a supervisor. The experimental results, that are evaluated using a number of dialogue tarns for each strategy, showed the importance of dialogue strategies.
