[ale] Mining PDF's

[Jeff Hubbs]

I was just poking through some PDFs I have here and it seems that if the
objective is to mine arbitrary PDFs, you might have a problem on your
hands.  I might be wrong, but it looks as though sometimes PDFs of text
are made from images of the text, not the text themselves, suggesting
that you'd have to OCR the images.  However, Google appears to do this
somehow, suggesting that you might be able to engineer something similar
or perhaps even make your PDF repository available to Google and use it
to search...
