Sentiment Analysis

Sentiment Analysis estimates the sentiment polarity (positive/negative) of text data

Dataiku provides several sentiment analysis capabilities

LLM-based sentiment analysis

The LLM Mesh has a native recipe for performing LLM-based sentiment analysis. This is usually the most performance option.

Please see our Tutorial for detailed information.

Offline sentiment analysis

The native sentiment analysis capability provides sentiment analysis in English.

It is an offline capability, meaning that it does not leverage a 3rd party API.

Note

This capability is provided by the “Sentiment analysis” plugin, which you need to install. Please see Installing plugins.
