Cross posted from my blog: Analyze the Data not the Drivel
Indexing documents is an ongoing chore. You would think picking out "good" book or article index words would be a trivial pseudo-sampling-sorting task, but that is not the case. Building a useful index requires something like "comprehending" the text. You must read the document, understand what's in it, and then judiciously select words that elucidate, navigate, and summarize the contents. Until recently, coding "reading comprehension" has been beyond my meager means. Then the other day, I had a brain fart; maybe ChatGPT can index LaTeX documents.
As a test, I decided to index my blog post Sympathy for Ptolemaic Epicyclers. For years I have been converting my WordPress blog posts to LaTeX with my J-based hack WordPress to LaTeX with Pandoc and J and storing the generated LaTeX code on GitHub. Here is the LaTeX for Ptolemaic Epicyclers. With code in hand, I logged into ChatGPT 3.5 and had this chat.
I first asked ChatGPT to summarize Sympathy for Ptolemaic Epicyclers.
Me: Please summarize the following text.
... upload of LaTeX code for Ptolemaic Epicyclers ...
ChatGPT: The provided text discusses the historical perspective of astronomy and the Ptolemaic system. It highlights that often, older theories are unfairly portrayed as ignorant and backward, whereas in reality, they were based on empirical observations and provided reasonable approximations. The text points out that the transition to new theories typically happens when the new model demonstrates its superiority in making predictions.
The author also mentions their recent work on a J script called "riseset," used for calculating when International Astronomical Union (IAU) stars culminate in their backyard. They explain that astronomical calculations, both in the past and today, are complex and require constant adjustments.
In conclusion, the text offers sympathy and respect for ancient astronomers who worked with limited tools and still made valuable contributions to understanding the cosmos. It emphasizes that these astronomers were not morons but rather practical philosophers trying to make sense of the observable universe.
If you read my blog post, you'll see that ChatGPT's summary is dead on. Also, ChatGPT's concluding remarks are better than mine. No wonder ChatGPT is scaring credentialed pseudo-intellectuals everywhere. I then asked.
Me: Please pick out good words to index from the text that you just summarized.
ChatGPT: Here are some good words or phrases to index from the summarized text:
Ptolemaic system, Old theory holdouts, Copernicus, Heliocentric model, Aristarchus, Sun-centered models, International Astronomical Union (IAU), GitHub, Astronomical calculations, Empirical observations, Modern calculations, N-body celestial mechanics, Gravitational theories, Backyard amateur astronomer, Ancient epicyclers
You can use these words or phrases as entries in the index of your LaTeX document to help readers easily find relevant information.
You'll notice that ChatGPT didn't just pick out words, it synthesized useful phrases that eerily sum up the contents of my post. I have no objections to the generated phrases even though I doubt I would have come up with them myself. I was impressed. This thing is a great
sounding board for writers.
Feeling lucky I decided to go for broke and ask ChatGPT to insert LaTeX indexing codes into my document.
Me: Please insert the latex index codes for the words you selected in the text I provided.
ChatGPT: Certainly! Here are the LaTeX index codes inserted into the provided text for the selected words:
... download of modified LaTeX code with \index{} commands inserted
...
ChatGPT effortlessly inserted the index codes into my document, and we concluded our chat with:
Me: Thank you
ChatGPT: You’re welcome! If you have any more questions or need further assistance, feel free to ask. Good luck with your LaTeX document!
