Norwegian is not supported

[emilmuller]

I'm doing keyword extraction in Norwegian. If I do not use Pattern, I'm getting stop words within the keyword extraction. E.g. if I extract the keywords from the first paragraph on Albert Einstein in the Norwegian Wikipedia:

Albert Einstein var en tyskfødt teoretisk fysiker og nobelprisvinner som er mest kjent for å ha formulert relativitetsteorien og vist at masse og energi er ekvivalente ved masseenergiloven, E = mc2. Gjennom den spesielle relativitetsteorien revolusjonerte han mekanikken og presiserte tidsbegrepet. Han var sentral i utviklingen av kvantemekanikken og er grunnleggeren av moderne kosmologi. Han regnes for å være en av de mest betydningsfulle vitenskapsmenn i det 20. århundre.

I'll get the following keywords:

• i
• og
• han
• hans
• av
• for å
• ble
• om
• einstein var en
• ved
• som er mest
• relativitetsteorien
• det
• fysikk
• med
• den
• verden
• verdens
• enn
• vitenskapelige
• århundre
• århundrets
• person
• første årene
• professor

I, og, av, for, å, ble, om, etc. are stop words, and as such, the result is unusable.

When installing Pattern, I just get:

    raise BadZipFile("File is not a zip file")
zipfile.BadZipFile: File is not a zip file

And so I cannot use Pattern (issue #30), making Norwegian unusable and unsupported. Assuming this goes for other languages as well.
