Amazon Comprehend (Key Phrases)

StreamableKNIME Amazon Machine Learning Integration version 4.3.0.v202011211914 by KNIME AG, Zurich, Switzerland

This node discovers key phrases within text by utilizing the Amazon Comprehend service. Amazon Comprehend is a natural language processing (NLP) service that uses machine learning to discover insights from text. The Comprehend service returns the key phrases or talking points and a confidence score to support that this is a key phrase. A key phrase consists of a noun and modifiers that distinguish the noun phrase (e.g. "a beautiful day").
The new data table contains a new row for every discovered key phrase as well as a score column which indicates the level of confidence that the text is a key phrase. Additionally, there are columns that define the start and end offsets of the key phrase within the input text. The offsets can be used to extract a key phrase from the original text

For more information about AWS Comprehend can be found on this website.
