AI总结:

针对传统方法处理长文档逻辑结构提取的不足,该研究提出端到端生成式方法Seg2Act,将任务重构为动作生成,通过全局上下文感知模型迭代生成动作并更新结构,在两个数据集的监督与迁移学习场景下均取得优异性能。

摘要:

文档逻辑结构构建旨在提取文档的底层层级结构,这对文档智能至关重要。传统方法在处理长文档的复杂性和可变性方面往往存在不足。为解决这些问题,我们提出Seg2Act——一种端到端的、基于生成的文档逻辑结构构建方法,将逻辑结构提取重构为动作生成任务。具体而言,给定文档的文本片段,Seg2Act通过全局上下文感知生成模型迭代生成动作序列,并根据生成的动作同时更新其全局上下文和当前逻辑结构。在ChCatExt和HierDoc数据集上的实验表明,Seg2Act在监督学习和迁移学习设置下均表现出优异性能。

英文摘要:

Document logical structuring aims to extract the underlying hierarchical structure of documents, which is crucial for document intelligence. Traditional approaches often fall short in handling the complexity and the variability of lengthy documents. To address these issues, we introduce Seg2Act, an end-to-end, generation-based method for document logical structuring, revisiting logical structure extraction as an action generation task. Specifically, given the text segments of a document, Seg2Act iteratively generates the action sequence via a global context-aware generative model, and simultaneously updates its global context and current logical structure based on the generated actions. Experiments on ChCatExt and HierDoc datasets demonstrate the superior performance of Seg2Act in both supervised and transfer learning settings.
