Quick Tutorial¶
import polyglot
from polyglot.text import Text, Word
Language Detection¶
text = Text("Bonjour, Mesdames.")
print("Language Detected: Code={}, Name={}\n".format(text.language.code, text.language.name))
Language Detected: Code=fr, Name=French
Tokenization¶
zen = Text("Beautiful is better than ugly. "
"Explicit is better than implicit. "
"Simple is better than complex.")
print(zen.words)
[u'Beautiful', u'is', u'better', u'than', u'ugly', u'.', u'Explicit', u'is', u'better', u'than', u'implicit', u'.', u'Simple', u'is', u'better', u'than', u'complex', u'.']
print(zen.sentences)
[Sentence("Beautiful is better than ugly."), Sentence("Explicit is better than implicit."), Sentence("Simple is better than complex.")]
Part of Speech Tagging¶
text = Text(u"O primeiro uso de desobediência civil em massa ocorreu em setembro de 1906.")
print("{:<16}{}".format("Word", "POS Tag")+"\n"+"-"*30)
for word, tag in text.pos_tags:
print(u"{:<16}{:>2}".format(word, tag))

Named Entity Recognition¶
text = Text(u"In Großbritannien war Gandhi mit dem westlichen Lebensstil vertraut geworden")
print(text.entities)
[I-LOC([u'Groxdfbritannien']), I-PER([u'Gandhi'])]
Polarity¶
print("{:<16}{}".format("Word", "Polarity")+"\n"+"-"*30)
for w in zen.words[:6]:
print("{:<16}{:>2}".format(w, w.polarity))
Word Polarity
------------------------------
Beautiful 0
is 0
better 1
than 0
ugly -1
. 0
Embeddings¶
word = Word("Obama", language="en")
print("Neighbors (Synonms) of {}".format(word)+"\n"+"-"*30)
for w in word.neighbors:
print("{:<16}".format(w))
print("\n\nThe first 10 dimensions out the {} dimensions\n".format(word.vector.shape[0]))
print(word.vector[:10])
Neighbors (Synonms) of Obama
------------------------------

Ahmadinejad

Morphology¶
word = Text("Preprocessing is an essential step.").words[0]
print(word.morphemes)
[u'Pre', u'process', u'ing']
Transliteration¶
from polyglot.transliteration import Transliterator
transliterator = Transliterator(source_lang="en", target_lang="ru")
print(transliterator.transliterate(u"preprocessing"))
