OK, this one would do. On this pdf file there are images of varying quality and with text embedded in various ways. This would be the typical text I would be dealing with: https://www.nysedregents.org/USHistoryGov/Archive/20020122exam.pdf another example of textual file I work with would be: https://scholarworks.iu.edu/dspace/bitstream/handle/2022/18961/Notes and Texts.pdf on that file pdftohtml produces one background file per page, but when you stratify the content (simply using hash signatures) you realize most files are of the same kind (just blank background images or files containing a single line (for example, underlining a title) or framing a blocked message), then there are full-page blank images with segments of greek text, ... I don't quite understand why poppler utils don't just underline a word. Of course, you could easily write some code to figure out which segments of text should be underlined, but understanding the obvious tends to pay in the long run > , neither what kind of tools you would > like to use (open source or proprietary) the poppler's pdftohtml tools: https://poppler.freedesktop.org/ are pretty good, but there is always an extra twicking you need.

Yes, I do, but a few heuristics included in metadata (extracted from the names and/or headings of files) are of great help At the end of the day you can't fully automate such a process. You will need a GUI and let "users" eye ball the data . . . > 5.

I am trying to write up a set of bash scripts and code as part of a pretty complete all-purpose library. Ideally the back end text will be formatter as ODT since it is very easy to convert it to any other format anyway Do you know of such a library? > [1] ...
