SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

输入一本书,输出它在认知史里挪动的那一步。通过分解核心问题、共识基线、独特洞见(delta)、落点,以及一张 ASCII 参考系图,帮助读者把复杂的书籍结构化成可操作的认知地图。

Core Features & Use Cases

  • 识别作者真正回答的核心问题,并将它与基线共识对比,标注 delta 的类型(修正、倒转、换轴),输出清晰的落点与行囊。
  • 生成含有五件事的分析框架(问题、零点、位移、落点、行囊)以及一个 ASCII 参考系图,便于可视化对照与讨论。
  • 适用于教育研究、书评写作、课程设计等场景,帮助将阅读转化为结构化知识产出。

Quick Start

给定一本书的标题与作者,即可生成该书的拆书结构、五件事要点及 ASCII 地图的初步输出。

FAQPage Schema
What is book analysis using a cognitive map and how does it structure reading notes?

Book analysis using a cognitive map distills a book's core question, baseline consensus, unique insight (delta), and takeaway into a structured five-step framework. It converts complex reading into an actionable knowledge structure with an ASCII reference diagram for visual comparison.

How do I break down a book into its core cognitive move and delta?

To break down a book into its cognitive move and delta, you identify the author's core question, compare it against the baseline consensus, and categorize the unique insight as a modification, reversal, or axis shift. This yields clear takeaways and a structured cognitive map.

Can I use this structured book analysis framework for philosophy and business books?

Yes, this structured book analysis framework is applicable to philosophy, science, and business books. It supports a repeatable workflow to extract cognitive shifts and generate structured notes across diverse educational and research domains.

What is the best way to generate an ASCII cognitive map for book reviews?

The best way to generate an ASCII cognitive map for book reviews is using a structured five-step analysis that outputs org-mode format. By inputting a book title and author, it produces a visual ASCII reference frame for easy comparison and discussion.

Do I need any specific dependencies or components to generate structured book notes?

No specific dependencies or components are required to generate structured book notes. You simply provide a book title and author to initiate the analysis, which outputs the five-step framework and ASCII map without needing external libraries.

Why should I use a delta-based framework instead of standard book summaries for knowledge work?

A delta-based framework identifies the exact cognitive shift a book contributes rather than just summarizing content. By mapping the baseline consensus against the unique delta, it creates a repeatable, actionable reference system for advanced knowledge work.
