چکیده

In this paper, we apply reinforcement learning for automatically learning cooperative persuasive dialogue system policies using framing, the use of emotionally charged statements common in persuasive dialogue between humans. In order to apply reinforcement learning, we describe a method to construct user simulators and reward functions specifically tailored to persuasive dialogue based on a corpus of persuasive dialogues between human interlocutors. Then, we evaluate the learned policy and the effect of framing through experiments both with a user simulator and with real users. The experimental evaluation indicates that applying reinforcement learning is effective for construction of cooperative persuasive dialogue systems which use framing.

Learning cooperative persuasive dialogue policies using framing

In this paper, we propose a new framework of cooperative persuasive dialogue, where a dialogue system simultaneously attempts to achieve user satisfaction while persuading the user to take some action that achieves a pre-defined system goal. Within this framework, we describe a method for reinforcement learning of cooperative persuasive dialogue policies by defining a reward function that refle...

Learning Adaptive Referring Expression Generation Policies for Spoken Dialogue Systems using Reinforcement Learning

Adaptive generation of referring expressions in dialogues is beneficial in terms of grounding between the dialogue partners. However, handcoding adaptive REG policies is hard. We present a reinforcement learning framework to automatically learn an adaptive referring expression generation policy for spoken dialogue systems.

Reinforcement Learning of Argumentation Dialogue Policies in Negotiation

We build dialogue system policies for negotiation, and in particular for argumentation. These dialogue policies are designed for negotiation against users of different cultural norms (individualists, collectivists, and altruists). In order to learn these policies we build simulated users (SUs), i.e. models that simulate the behavior of real users, and use Reinforcement Learning (RL). The SUs ar...

Learning dialogue policies using state aggregation in reinforcement learning

The learning of dialogue strategies in spoken dialogue systems using reinforcement learning is a promising approach to acquire robust dialogue strategies. However, the trade-off between available dialogue data and information in the dialogue state either forces information to be excluded from the state representations or requires large amount of training data. In this paper, we propose to use d...

Construction and Analysis of a Persuasive Dialogue Corpus

Persuasive dialogue systems, systems which are not passive actors, but actually try to change the thoughts or actions of dialogue participants, have gained some interest in recent dialogue literature. In order to construct more effective persuasive dialogue systems, it is important to understand how the system’s human counterparts perform persuasion. In this paper, we describe the construction ...
