Scraping news articles

news articles

Followed the tutorial here on scraping newspaper articles and performing sentiment analysis. Made changes to use different set of dictionary and analysis tools.

Sentiment analysis using VADER and a simple dictionary using a corpus of postive and negative words.

Corpus from: http://www.cs.uic.edu/~liub/FBS/sentiment-analysis.html

Results:
