Binary classification sentiment analysis is now performed on linked page contents and submission title. If either title or page contents has a positivity >0.9 or their average is >0.8 the news is considered positive.
Contact /u/_Timboss if you have any queries, ideas or suggestions, or you would like the bot to post to your subreddit.
The GoodNewsBot is currently in Beta and it's results may be unreliable, but are typically 70-80% accurate. I'm still experimenting with the services used to determine positiveness so this will hopefully improve in the future.
Please get in contact if you have any experience in training sentiment analysis models!
