The Watson Natural Language Processing Concepts block extracts general DBPedia concepts (concepts drawn from language-specific Wikipedia versions) that are directly referenced or alluded to, but not directly referenced, in the input text.

Block name

concepts_alchemy_<language>_stock

Supported languages

The Concepts block is available for the following languages. For a list of the language codes and the corresponding language, see Language codes.

de, en, es, fr, it, ja, ko, pt

Capabilities

Use this block to assign concepts from DBPedia (2016 edition). The output types are based on DBPedia.

Dependencies on other blocks

The following block must run before you can run the Concepts extraction block:

• syntax_izumo_<language>_stock

Code sample

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)

Output of the code sample:
