International Business Machines Corp. Sentiment Analysis Graph - IBMAbout Sentiment Analysis
Using sentiment analysis for predicting stock prices is a fairly new field. The idea is that you can use text mining and opinion mining with Natural Language Processing (NLP) to gauge the underlying meaning of text, and to derive an overall impact of that meaning. Our sources include major news websites, stock journals, message boards, and more. All data is updated in real-time. The idea that drove sentiment was to have a computer act as your investment adviser, who is constantly up to date on all the news for a company.
