Sentiment on Word document is incorrect



When executing a Sentiment on a Word document, it is stated as Neutral or Undetected. However, in the out-of-the-box Text Analyzers, the same words are categorized as a Positive or Negative sentiment. This occurs when using the Text Analyzer's Sentiment Analysis feature.

Error Messages

Not Applicable

Steps to Reproduce

Execute the Text Analyzer with Sentiment Analysis enabled.

Root Cause

A defect in Pegasystems’ code or rules.

In the Text Analyzer rule, for Sentiment Analysis the threshold values (decimal control) are modified for a few operator locales when the rule is saved. For a few locales, the decimal separator is considered as a comma (,). Hence on performing a Save, an incorrect value is saved to the rule.


Perform the following local-change: 
  1. When saving the rule, change the operator locale to en_US.
  2. Revert to the operator locale when the changes are completed to the rule.
