Watson Natural Language Processing Concepts 块会抽取一般 DBPedia 概念 (从特定于语言的维基百科版本中抽取的概念) ，这些概念在输入文本中直接引用或间接引用但未直接引用。

块名

concepts_alchemy_<language>_stock

受支持的语言

"概念" 块可用于以下语言。 有关语言代码和相应语言的列表，请参阅 语言代码。

de ， en ， es ， fr ， it ， ja ， ko ， pt

功能

使用此块可从 DBPedia (2016 版) 分配概念。 输出类型基于 DBPedia。

对其他块的依赖关系

必须先运行以下块，然后才能运行 Concepts 抽取块:

• syntax_izumo_<language>_stock

代码样本

import watson_nlp

# Load Syntax and a Concepts model for English
syntax_model = watson_nlp.load('syntax_izumo_en_stock')
concepts_model = watson_nlp.load('concepts_alchemy_en_stock')
# Run the syntax model on the input text
syntax_prediction = syntax_model.run('IBM announced new advances in quantum computing')

# Run the concepts model on the result of syntax
concepts = concepts_model.run(syntax_prediction)
print(concepts)

代码示例的输出：
