Generic text summarization approaches often fail to address the specific
intent and needs of individual users. Recently, scholarly attention has turned
to the development of summarization methods that are more closely tailored and
controlled to align with specific objectives and user needs. While a growing
corpus of research is devoted towards a more controllable summarization, there
is no comprehensive survey available that thoroughly explores the diverse
controllable aspects or attributes employed in this context, delves into the
associated challenges, and investigates the existing solutions. In this survey,
we formalize the Controllable Text Summarization (CTS) task, categorize
controllable aspects according to their shared characteristics and objectives,
and present a thorough examination of existing methods and datasets within each
category. Moreover, based on our findings, we uncover limitations and research
gaps, while also delving into potential solutions and future directions for
CTS.

总结特定用户的需要和意图，关注于开发更贴合特定目标和用户需求的文本摘要方法。最近的学术关注点转向了更可控的摘要方法的发展，但缺乏全面的调查来深入探索在这一背景下所使用的各种可控性方面或属性，并研究现有的解决方案。在本调查中，我们形式化了可控文本摘要任务，根据它们的共享特征和目标将可控性方面进行分类，并对每个类别中的现有方法和数据集进行了全面的研究。此外，根据我们的调查结果，我们发现了一些限制和研究空白，同时也探讨了 CTS 的潜在解决方案和未来发展方向。

Controllable Text Summarization: Unraveling Challenges, Approaches, and  Prospects -- A Survey

Learning to control an environment without hand-crafted rewards or expert
data remains challenging and is at the frontier of reinforcement learning
research. We present an unsupervised learning algorithm to train agents to
achieve perceptually-specified goals using only a stream of observations and
actions. Our agent simultaneously learns a goal-conditioned policy and a goal
achievement reward function that measures how similar a state is to the goal
state. This dual optimization leads to a co-operative game, giving rise to a
learned reward function that reflects similarity in controllable aspects of the
environment instead of distance in the space of observations. We demonstrate
the efficacy of our agent to learn, in an unsupervised manner, to reach a
diverse set of goals on three domains -- Atari, the DeepMind Control Suite and
DeepMind Lab.
