摘要检查链 Summarization checker chain
本笔记本展示了在不同类型的文本中使用LLMSummarizationCheckerChain的一些示例。它与
LLMCheckerChain有几个明显的不同之处，即它不对输入文本（或摘要）的格式有任何假设。另外，由于LLM在进行事实检查或因上下文混淆时容易产生错觉，有时多次运行检查器会更有利。
它通过将重写的“真实”结果反馈给自己，并检查“事实”的真实性来实现这一点。从下面的示例可以看出，这在得到一个基本真实的文本体时可以非常有效。
您可以通过设置max_checks参数来控制检查器运行的次数。默认值是2，但如果您不希望进行任何双重检查，可以将其设置为1。

Your 9-year old might like these recent discoveries made by The James Webb Space Telescope (JWST):
• In 2023, The JWST spotted a number of galaxies nicknamed "green peas." They were given this name because they are small, round, and green, like peas.
• The telescope captured images of galaxies that are over 13 billion years old. This means that the light from these galaxies has been traveling for over 13 billion years to reach us.
• JWST took the very first pictures of a planet outside of our own solar system. These distant worlds are called "exoplanets." Exo means "from outside."
These discoveries can spark a child's imagination about the infinite wonders of the universe."""
