Zusammenfassung
In recent years some researchers have explored the use of reinforcement learning (RL)
algorithms as key components in the solution of various natural language processing
(NLP) tasks. For instance, some of these algorithms leveraging deep neural learning have
found their way into conversational systems. This paper reviews the state of the art of RL
methods for their possible use for different problems of NLP, focusing primarily on conver-
sational systems, mainly due to their growing relevance. We provide detailed descriptions
of the problems as well as discussions of why RL is well-suited to solve them. Also, we
analyze the advantages and limitations of these methods. Finally, we elaborate on promis-
ing research directions in NLP that might benefit from RL.
