Opinion Crawl | Big Policy Canvas

Opinion Crawl is an online sentiment analysis for current events, companies, products, and people. Opinion Crawl allows visitors assess Web sentiment on a topic – a person, an event, a company or a product. The user can enter a topic and get an ad-hoc sentiment assessment of it. For each topic, the user gets a pie chart showing current real-time sentiment, a list of the latest news headlines, a few thumbnail images, and a tag cloud of key semantic concepts that the public associates with the subject. The concepts allow to see what issues or events drive the sentiment in a positive or negative way. For more in-depth assessment, the web crawlers would find the latest published content on many popular subjects and current public issues and calculate sentiment for them on ongoing basis. Then the blog posts would show the trend of sentiment over time, as well as the Positive-to-Negative ratio
