Sentiment analysis inspects end-user input
and identifies the prevailing subjective opinion,
especially to determine an end-user's attitude as
positive, negative, or neutral.
When making a detect intent request,
you can specify that sentiment analysis be performed,
and the response will contain sentiment analysis values.
Supported languages
For a list of supported languages, see the sentiment column on the
language reference.
If you request sentiment analysis for an unsupported language,
your detect intent request does not fail,
but the QueryResult.diagnostic_info field contains error information.
Detect intent
Using the API, you can request sentiment analysis for each
detectIntent or streamingDetectIntent call
by setting the analyzeQueryTextSentiment field to true.
The response contains a sentimentAnalysisResult field
with score and magnitude values.
Using sentiment in conditions
You can use sentiment analysis results via the request-scoped parameters when defining a condition.
