Opinion Crawl – Web sentiment analysis, The Next Web (May 2)
Semantic Engines, creator of SenseBot for semantic search, has turned to opinion and sentiment analysis. OpinionCrawl.com - assesses Web sentiment on a subject – a person, an event, a company or product.
For oil spill it shows a pie chart of positive, negative, and neutral slices. (Hard to know how there can be 34% positive sentiment on that). Also a tag cloud of words - but no links. Get a a better idea of the analysis from Sarah Palin which shows trend in changing opinion.
Semantic Engines does not reveal sources or methods. This is likely a showcase for for-fee analysis they can do for your company. As a public tool, it's not as useful as working with Google Trends or some of the tools that analyze twitter streams.
