This old method is for Windows users, but the principles can be applied in Linux as well. It is for creating a subject specific glossary in a specific software translation project. The idea is to get a list of commonly used jargon from the project that can be translated beforehand.
Take the PO file and do po2csv on it:
po2csv file.po file.csv
Open the CSV file in Excel or Calc.
Copy the “original” (or “source”) column into a text editor, like Babelpad, and save the file as text.txt.
Use ExtPhr32 to extract the most used terms from it:
Create a file containing the 3000 most used words in English. I used Ogden’s 850 words, plus the 3000 words, adjectives, adverbs and pronouns from here, but you could use Kevin’s lists as well (actually, that would be better because then you could legally distribute it).
Use Kastrul to spellcheck the “5ormore.txt”:
That is your glossary. Remember to change it all to lowercase, and to ensure that dud words are removed.
