布巴内斯瓦尔是城市

Answer 1

因此，根据您的评论句子:

"mba college in bhubaneswar"

将其放入 NLU 中，实体检测失败，并显示:

Error: unsupported text language: unknown, Code: 400

第一个问题是，由于未指定语言，因此它会尝试猜测语言。但没有足够的地方可以猜测(即使这对你来说是显而易见的)。

第二个问题是，即使您指定了语言，它也无法完全识别。这是因为它不是一个真正的句子，而是一个片段。

NLU 不仅仅进行关键字查找，它还尝试理解词性 (POS)，并据此确定该词的含义。

所以如果我给它一个真正的句子，它就会起作用。例如:

I go to an MBA college in Bhubaneswar

我使用了这个示例代码:

import json
from watson_developer_cloud import NaturalLanguageUnderstandingV1
from watson_developer_cloud.natural_language_understanding_v1 import Features, EntitiesOptions, RelationsOptions

ctx = {
  "url": "https://gateway.watsonplatform.net/natural-language-understanding/api",
  "username": "USERNAME",
  "password": "PASSWORD"
}
version = '2017-02-27'

text = "I go to an MBA college in Bhubaneswar"
#text = "mba college in bhubaneswar"

nlu = NaturalLanguageUnderstandingV1(version=version, username=ctx.get('username'),password=ctx.get('password'))
entities = EntitiesOptions()
relations = RelationsOptions()

response = nlu.analyze(text=text, features=Features(entities=entities,relations=relations),language='en')

print(json.dumps(response, indent=2))

这给了我以下结果。

    "text_units": 1,
    "text_characters": 37,
    "features": 2
  },
  "relations": [

          ]
        },
        {
          "text": "Bhubaneswar",
          "location": [
            26,
            37
          ],
          "entities": [
            {
              "type": "GeopoliticalEntity",

            }
          ]
        }
      ]
    }
  ],
  "language": "en",
