We propose a text editor to help users plan, structure and reflect on their
writing process. It provides continuously updated paragraph-wise summaries as
margin annotations, using automatic text summarization. Summary levels range
from full text, to selected (central) sentences, down to a collection of
keywords. To understand how users interact with this system during writing, we
conducted two user studies (N=4 and N=8) in which people wrote analytic essays
about a given topic and article. As a key finding, the summaries gave users an
external perspective on their writing and helped them to revise the content and
scope of their drafted paragraphs. People further used the tool to quickly gain
an overview of the text and developed strategies to integrate insights from the
automated summaries. More broadly, this work explores and highlights the value
of designing AI tools for writers, with Natural Language Processing (NLP)
capabilities that go beyond direct text generation and correction.

本文提出了一个文本编辑器，使用自动文本摘要为用户提供不断更新的逐段摘要，以边缘注释的方式帮助用户规划、结构化和反思写作过程。通过两个用户研究，作者发现这个系统为用户提供了一个外部的视角来帮助他们修改段落的内容和范围，并且帮助用户快速了解文本的总体情况和开发一些集成自动摘要中得到的见解的策略。通过探究和强调设计 AI 工具以帮助写作的价值，这项工作突显了自然语言处理 (NLP) 能够超越直接的文本生成和纠正。
