我使用NLTK和Maltparser從自然語言中的句子中提取依賴關係。我沒有使用斯坦福解析器使用此代碼一些實驗:使用NLTK和MaltParser的依賴關係解析器
sentence = '''I shot an elephant in my pajamas'''
os.popen("echo '"+sentence+"' > ~/stanfordtemp.txt")
parser_out = os.popen("/usr/local/Cellar/stanford-parser/2.0.3/bin/lexparser.sh ~/stanfordtemp.txt").readlines()
for i, tag in enumerate(parser_out):
if len(tag.strip()) > 0 and tag.strip()[0] == '(':
parse = " ".join(tag.strip())
print i, "Parse: ", tag
elif len(tag.strip()) > 0:
print i, "Typed dependencies: ", tag
bracketed_parse = " ".join([tag.strip() for tag in parser_out if len(tag.strip()) > 0 and tag.strip()[0] == "("])
print bracketed_parse
,並有這樣好的結果:
Parsing [sent. 1 len. 7]: I shot an elephant in my pajamas
Parsed 7 words in 1 sentences (12,87 wds/sec; 1,84 sents/sec).
0 Parse: (ROOT
1 Parse: (S
2 Parse: (NP (PRP I))
3 Parse: (VP (VBD shot)
4 Parse: (NP (DT an) (NN elephant))
5 Parse: (PP (IN in)
6 Parse: (NP (PRP$ my) (NNS pajamas))))))
8 Typed dependencies: nsubj(shot-2, I-1)
9 Typed dependencies: root(ROOT-0, shot-2)
10 Typed dependencies: det(elephant-4, an-3)
11 Typed dependencies: dobj(shot-2, elephant-4)
12 Typed dependencies: poss(pajamas-7, my-6)
13 Typed dependencies: prep_in(shot-2, pajamas-7)
隨着MaltParser我有這樣的代碼:
os.environ['MALTPARSERHOME']="/Applications/maltparser-1.7.2"
maltParser = nltk.parse.malt.MaltParser(working_dir="/Applications/maltparser-1.7.2",
mco="engmalt.linear-1.7",
additional_java_args=['-Xmx1024m'])
txt = '''I shot an elephant in my pajamas'''
graph = maltParser.raw_parse(txt)
print(graph.tree().pprint())
和後續輸出:
(pajamas (shot I) an elephant in my)
問題:我可以使用與使用斯坦福解析器時相同的輸出嗎?任何幫助都會很棒。
嘿你找到任何方法嗎? –
沒有不幸的不是! – Marcelo
