NLTK tag Dutch sentence
<p>I am beginning with NLTK and want to tag a Dutch sentence but I am having trouble specifying the corpus. </p>

<pre><code>from nltk.tag import pos_tag
from nltk.tokenize import word_tokenize
from nltk.corpus import alpino

pos_tag(word_tokenize("Python is een goede data science taal."), tagset = 'alpino')
</code></pre>

<p>gives,</p>

<pre><code>[('Python', 'UNK'),
 ('is', 'UNK'),
 ('een', 'UNK'),
 ('goede', 'UNK'),
 ('data', 'UNK'),
 ('science', 'UNK'),
 ('taal', 'UNK'),
 ('.', 'UNK')]
</code></pre>

<p>So clearly I am not specifying the corpus correctly. I downloaded the alpino corpus. Can anyone help me to figure out how to specify the corpus correctly?</p>
