title: How do I do word Stemming or Lemmatization?
body: <p>I've tried PorterStemmer and Snowball but both don't work on all words, missing some very common ones. </p>
  
  <p>My test words are: "<strong>cats running ran cactus cactuses cacti community communities</strong>", and both get less than half right.</p>
