How do I see word frequency with OpenOffices Writer?
Here is an extension that may be helpful: http://extensions.services.openoffice.org/en/project/Linguist “The extension has been enhanced with commands for making complete lists of all words in a text document – either as an alphabetical list or sorted after word frequency – and with a readability calculating function that expresses readability in a unit called Lix.” It is platform independent, so it should work with Ubuntu.
