trioptimum/pdf-ocr-score: naive shell script to gauge the OCR quality of a PDF

A very basic shell script that I'm using to gauge the quality of already OCRed PDFs. Takes the filename of a PDF as a parameter, and prints the total word count, the count of words not known by aspell, and the percentage of unknown words. A good PDF (exported straight from the original source) likely has an unknown rate of around 5%, while a poorly OCRed scan of questionable quality may be 20% or higher.

Requires pdftotext and aspell.

olduse.net

olduse.net was an interactive art installation conceived and implemented by Joey Hess that ran from 2011 to 2021.

olduse.net was posting the first 10 years of archived usenet articles to a news server, replaying usenet as it happened 30 years earlier. It also had a web interface with an interactive news reader, allowing you to access the news server via the web instead of using nntp.

The project is available at https://article.olduse.net/

The current version publishes news from 30 years ago, and some versions have a delay of 40 to 45 years.
