Thank you for the interest in NodeXL!You can find the features for text analysis in this NodeXL menu:
NodeXL>Analysis>Graph Metrics>Words and Word Pairs>Options>Sentiment:
There you will see the Word and Word Pair Metrics dialog:
This dialog allows you to edit the lists of words that are to be skipped or categorized as List #1, #2, or #3.
NodeXL ships with a default collection of American English language "Positive", "Negative", and "Angry/Violent" terms.
You may modify or replace these lists.
You may RENAME these lists as well.
You may use any language to populate these lists.
These lists do not need to be "Positive" and "Negative" words. Consider student versus teacher words, or investor versus consumer words, or even lists of words that are distinctive of different languages.
