The document-level Sentiment Analysis module analyzes a piece of text and determines whether the text has a positive or negative sentiment.
It supports any sentiment-bearing text (that is, texts which are not too short, numeric, include only a street address, or an IP address). This module works best if the input text is over 40 characters in length.
Configuration options
This module never runs automatically during a Data Processing workflow.
In addition, the Transform API has a getSentiment function that wraps this module.
Output
Note that NULL is returned for any input which is either null or empty.
The output string is subsequently ingested into the Dgraph as a single-assign string Dgraph attribute. The name of the output attribute is <attribute>_doc_sent
.
