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 &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。
