我的CODE是
from nltk.parse import malt mp = malt.MaltParser(working_dir="/other/apps/maltparser-1.8.1",mco="engmalt.poly-1.7.mco",additional_java_args=['-Xmx1024m']) print mp.raw_parse("Hello World") 而错误是
Traceback (most recent call last): File "malt.py", line 13, in <module> print mp.raw_parse("Hello World") File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 139, in raw_parse return self.parse(words, verbose) File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 126, in parse return self.parse_sents([sentence], verbose)[0] File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 114, in parse_sents return self.tagged_parse_sents(tagged_sentences, verbose) File "/usr/local/lib/python2.7/dist-packages/nltk/parse/malt.py", line 194, in tagged_parse_sents "code %d" % (' '.join(cmd), ret)) Exception: MaltParser parsing (java -Xmx1024m -jar /usr/local/bin/malt.jar -w /other/apps/maltparser-1.8.1 -c engmalt.poly-1.7.mco -i /other/apps/maltparser-1.8.1/malt_input.conlljOba1P -o /other/apps/maltparser-1.8.1/malt_output.conllPLcoTu -m parse) failed with exit code 1
NLTK中的MaltParser API只有一个修补程序 ，可以修复和稳定以前的问题：
下面是一个如何在NLTK中使用MaltParser API的例子：
# Upgrade your NLTK. alvas@ubi:~$ cd ~ alvas@ubi:~$ pip install -U nltk # Get the latest MaltParser and model alvas@ubi:~$ wget http://maltparser.org/dist/maltparser-1.8.1.zip alvas@ubi:~$ unzip maltparser-1.8.1.zip alvas@ubi:~$ wget http://www.maltparser.org/mco/english_parser/engmalt.poly-1.7.mco # In python, now you can do this: alvas@ubi:~$ python >>> from nltk.parse.malt import MaltParser >>> mp = MaltParser('/home/alvas/maltparser-1.8.1', '/home/alvas/engmalt.poly-1.7.mco') >>> sent1 = 'I shot an elephant in my pajamas .'.split() >>> print(mp.parse_one(sent1).tree()) (shot I (elephant an (in (pajamas my))) .)
（ 在这里可以看到更多的演示代码或者更详细的演示代码）
请注意，您也可以使用导出功能，并且可以在初始化MaltParser对象时避免使用完整路径。 但是你仍然要告诉对象什么是分析器目录和模型文件名的名字来查找，例如
alvas@ubi:~$ export MALT_PARSER='/home/$UID/maltparser-1.8.1/' alvas@ubi:~$ export MALT_MODEL='/home/$UID/engmalt.poly-1.7.mco' alvas@ubi:~$ python >>> from nltk.parse.malt import MaltParser >>> mp = MaltParser('maltparser-1.8.1', 'engmalt.poly-1.7.mco') >>> sent1 = 'I shot an elephant in my pajamas .'.split() >>> print(mp.parse_one(sent1).tree()) (shot I (elephant an (in (pajamas my))) .)
