  • 【问题和解决】NLTK7.6节nltk.sem遇到的问题

    Traceback (most recent call last):
    File "<pyshell#155>", line 3, in <module>
    print nltk.sem.show_raw_rtuple(rel,Icon=True,rcon=True)
    AttributeError: 'module' object has no attribute 'show_raw_rtuple'

    在7.6关系抽取中,有这样一段代码

    >>>IN = re.compile(r'.*\bin\b(?!\b.+ing)')
    >>>for docin nltk.corpus.ieer.parsed_docs('NYT_19980315'):
    ... for rel in nltk.sem.extract_rels('ORG', 'LOC', doc,
    ... corpus='ieer',pattern = IN):
    ... print nltk.sem.show_raw_rtuple(rel)
    [ORG: 'WHYY'] 'in' [LOC: 'Philadelphia']
    [ORG: 'McGlashan &AMP;Sarrail']'firm in' [LOC: 'San Mateo']
    [ORG: 'Freedom Forum']'in' [LOC: 'Arlington']
    [ORG: 'Brookings Institution'] ', the research group in' [LOC: 'Washington']
    [ORG: 'Idealab'] ', a self-described businessincubator basedin' [LOC: 'Los Angeles']
    [ORG: 'Open Text']', basedin' [LOC: 'Waterloo']
    [ORG: 'WGBH'] 'in' [LOC: 'Boston']
    [ORG: 'Bastille Opera']'in' [LOC: 'Paris']
    255
    [ORG: 'Omnicom'] 'in' [LOC: 'New York']
    [ORG: 'DDB Needham']'in' [LOC: 'New York']
    [ORG: 'Kaplan ThalerGroup']'in' [LOC: 'New York']
    [ORG: 'BBDO South']'in' [LOC: 'Atlanta']
    [ORG: 'Georgia-Pacific'] 'in' [LOC: 'Atlanta']

    其中有一句是

    nltk.sem.show_raw_rtuple(rel),但是运行出现了错误,提示没有此方法。
    经过查询NLTK.sem的文档,发现这些函数都在更深的地方。也就是
    nltk.sem.relextract中。
