The Sentiment Analysis tool in Gale Digital Scholar Lab enables users to visualise the average sentiment score of each document in a Content Set, facilitating comparison and investigation.  

Sentiment Analysis compares words contained in a document or documents with a predefined lexicon - a list of human-labelled words with a corresponding sentiment score of 5 (very positive) to -5 (very negative).  

Users can plot Sentiment scores of their documents over time to track changes in sentiment within a Content Set, and drill into individual documents to investigate the changes in sentiment throughout the work.
