Argument Summarization: A Unified Task Definition, Taxonomy, and Survey

Zhiqiang Shi, Oana Cocarascu


Abstract
Argument summarization seeks to generate concise representations of argumentative content while preserving argumentative meaning, yet the field remains conceptually fragmented. In this survey, we provide a unified task definition of argument summarization that encompasses both argumentative text summarization and key point analysis, and introduce a taxonomy along input structure, output representation, and the role of argumentative structure. Using this framework, we analyze the evolution of the field and systematically review existing datasets, methods, and evaluation practices, revealing misalignment that hinders comparability and progress. We further situate argument summarization within the broader context of generic text summarization, identifying practical limitations and intrinsic challenges. Finally, we outline promising future research directions.
