sys.path.append(os.path.join(os.getcwd(),'..'))
import watson_developer_cloud
import watson_developer_cloud.natural_language_understanding.features.v1 as features
nlu = watson_developer_cloud.NaturalLanguageUnderstandingV1(version='2017-02-27',
username='some_username',
password='some_password')
nlu.analyze(text='this is my experimental text. Bruce Banner is the Hulk and Bruce Wayne is BATMAN! Superman fears not Banner, but Wayne.',
features=[features.Entities(), features.Keywords()])
It generates the following output: 它生成以下输出:
{'entities': [{'count': 3,

'text': 'Bruce Banner',
'type': 'Person'},
{'count': 1, 'relevance': 0.296395, 'text': 'Wayne', 'type': 'Person'}],
'keywords': [{'relevance': 0.984789, 'text': 'Bruce Banner'},
{'relevance': 0.958833, 'text': 'Bruce Wayne'},
