# Senpy Plugin Taiger
|
||||
|
||||
Service that analyzes sentiments from social posts written in Spanish or English.
|
||||
Proxy for two of Taiger's sentiment analysis services for social media posts:
|
||||
|
||||
* taiger-plugin: proxy for a service that normalizes the text, and gives both a polarity and a polarity value for the text. It works for Spanish and English text.
|
||||
* taiger3c-plugin: it uses a simpler service that only returns a polarity (positive, negative or none). It only works for Spanish.
