German language support for TextBlob.
Project description
German language support for TextBlob by Steven Loria.
This python package is being developed as a TextBlob Language Extension. See Extension Guidelines for details.
Features
TextBlobDE class with initialized default models for German
German sentence boundary detection (NLTKPunktTokenizer)
Consistent use of specified tokenizer for all tools (NLTKPunktTokenizer or PatternTokenizer)
Part-of-speech tagging (PatternTagger)
Parsing (PatternParser)
Polarity detection (PatternAnalyzer) EXPERIMENTAL (only recognises uninflected word forms and does not have information on subjectivity)
Supports Python 2 and 3
See working features overview for details
Installing/Upgrading
$ pip install -U textblob-de $ python -m textblob.download_corpora
Or the latest development release (apparently this does not always work on Windows see issues #1744/5 for details):
$ pip install -U git+https://github.com/markuskiller/textblob-de.git@dev $ python -m textblob.download_corpora
Usage
>>> from textblob_de import TextBlobDE as TextBlob
>>> text = '''Heute ist der 3. Mai 2014 und Dr. Meier feiert seinen 43. Geburtstag.
Ich muss unbedingt daran denken, Mehl, usw. für einen Kuchen einzukaufen. Aber leider
habe ich nur noch EUR 18.50 in meiner Brieftasche.'''
>>> blob = TextBlob(text)
>>> blob.sentences
[Sentence("Heute ist der 3. Mai 2014 und Dr. Meier feiert seinen 43. Geburtstag."),
Sentence("Ich muss unbedingt daran denken, Mehl, usw. für einen Kuchen einzukaufen."),
Sentence("Aber leider habe ich nur noch EUR 18.50 in meiner Brieftasche.")]
>>> blob.tokens
WordList(['Heute', 'ist', 'der', '3.', 'Mai', ...]
>>> blob.tags
[('Heute', 'RB'), ('ist', 'VB'), ('der', 'DT'), ('3.', 'LS'), ('Mai', 'NN'),
('2014', 'CD'), ...]
>>> blob = TextBlob("Das Auto ist sehr schön.")
>>> blob.parse()
'Das/DT/B-NP/O Auto/NN/I-NP/O ist/VB/B-VP/O sehr/RB/B-ADJP/O schön/JJ/I-ADJP/O'
>>> blob = TextBlob(text, parser_show_lemmata=True)
'Das/DT/B-NP/O/das Auto/NN/I-NP/O/auto ist/VB/B-VP/O/sein sehr/RB/B-ADJP/O/sehr' \
'schön/JJ/I-ADJP/O/schön ././O/O/.'
>>> blob = TextBlob("Das Auto ist sehr schön.")
>>> blob.sentiment
(1.0, 0.0)
>>> blob = TextBlob("Das Auto ist hässlich.")
>>> blob.sentiment
(-1.0, 0.0)
Requirements
Python >= 2.6 or >= 3.3
TODO
Implement German noun phrase extractor
Additional PoS tagging options NLTK tagging (NLTKTagger)
Improve sentiment analysis (find suitable subjectivity scores and look up lemmas rather than word forms)
