![]() In this tutorial, we saw examples of how to perform Named Entity Recognition or NER in NLTK library of Python We also understood what are the uses of NER and did a comparison between POS Tagging vs NER.

To use the tagger you can simply call postag(tokens). Here is the documentation for PerceptronTagger and here is the source code. Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, Python, PHP, Bootstrap, Java. POS tagger looks for one word at a time whereas NER looks for multiple words detecting the type of Named Entity, as well as the word boundaries. According to the source code, postag uses NLTK's currently reccomended POS tagger, which is PerceptronTagger as of 2018.Word recognized as a noun by a POS tagger is passed for the NER process. The output of POS tagging is used as an input for NER.POS tagger does not look for the relation between the words in the document whereas NER looks for the relationship between words.Next article Tensorflow.js Hand Gesture Recognition and Tracking using Handpose Model.
