A Part-Of-Speech Tagger (POS Tagger) is a piece of software that readstext in some language and assigns parts of speech to each word (andother token), such as noun, verb, adjective, etc., although generallycomputational applications use more fine-grained POS tags like'noun-plural'. ), ('it', 'PRP'), ('is', 'VBZ'), ('working', 'VBG'), ('great', 'JJ')], ), ('is', 'VBZ'), ('hanging', 'VBG'), ('very', 'RB'), ('often', 'RB')], ), ('for', 'IN'), ('last', 'JJ'), ('5', 'CD'), ('years', 'NNS'), (',', ','), ('he', 'PRP'), ('is', 'VBZ'), ('happy', 'JJ'), ('with', 'IN'), ('it', 'PRP')]. The task of POS-tagging is to labeling words of a sentence with their appropriate Parts-Of-Speech (Nouns, Pronouns, Verbs, Adjectives …). To perform Parts of Speech (POS) Tagging with NLTK in Python, use nltk.pos_tag() method with tokens passed as argument. First let me check tags for those sentences: [('I', 'PRP'), ('am', 'VBP'), ('using', 'VBG'), (, ), ('note5', 'NN'), ('it', 'PRP'), ('is', 'VBZ'), ('working', 'VBG'), ('great', 'JJ')], ), ('s7', 'NN'), ('is', 'VBZ'), ('hanging', 'VBG'), ('very', 'RB'), ('often', 'RB')], ), ('g5', 'NN'), ('for', 'IN'), ('last', 'JJ'), ('5', 'CD'), ('years', 'NNS'), (',', ','), ('he', 'PRP'), ('is', 'VBZ'), ('happy', 'JJ'), ('with', 'IN'), ('it', 'PRP')], You can see that all those entity I wanted to extract is coming under “, Extracting all Nouns (NNP) from a text file using nltk, See now I am able to extract those entity (, Automatickeyword extraction using TextRank in python, AutomaticKeyword extraction using Topica in Python, AutomaticKeyword extraction using RAKE in Python.
