StanfordNLP / PartofspeechTagger / 0.1.0
Input a piece of text, get back the same piece of text with the parts of speech tagged according to the Stanford CoreNLP MaxEnt Tagger. You can find a large list of pretrained taggers in the "data://StanfordNLP/models/" directory, including English (multiple taggers), Arabic, German, Chinese, and Spanish. If you do not specify a tagger model a default English one will be used.

Parts are tagged according to the conventions of the Penn Treebank Project ( For example, a plural noun is denoted NNS, a singular or mass noun is NN, and a determiner (such as a/an, every, no, the, another, any, some, each, etc.) as DT.
