Online sentiment analysis for current events, companies, products, and people!
Opinion Crawl allows visitors to assess Web sentiment on a topic - a person, an event, a company or a product.
You can enter a topic and get an ad-hoc sentiment assessment of it.
For each topic you get 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 you to see what issues or events drive the sentiment in a positive or negative way.
If you want to look at the sentiment trend or get a more in-depth assessment, go to our automated blog. All posts in the blog are generated automatically and updated daily. Our Web crawlers find the latest published content on many popular subjects and current public issues, and calculate sentiment for them on an ongoing basis. The blog posts show the trend of sentiment over time, as well as the Positive-to-Negative ratio.
The cloudMonitoring the cloud of concepts over time, you can see the change in the issues and key topics that the public associates with the subject, and how it affects the sentiment. The concepts are mined from the Web pages using our semantic engine SenseBot.
How we measure the sentiment:Let's say you are looking for a sentiment on New York. Instead of just calculating the number of statements like "I love NY" or "I hate NY", we assess an overall sentiment towards the subject. In case of New York, we would take into account major events that affect people's feelings about it, like elections, crime, traveler's impressions, etc. As a result, the sentiment is covering the subject from all aspects. Note that the sentiment is almost never 100% positive or negative. Even a horrible event like an earthquake can display a measure of positive sentiment - for instance, reflecting the success of relief efforts.
In-depth reportsOur intelligent crawlers process large amounts of various Web sources - blogs, news sites, forums, Twitter. Sentiment reports are produced on an ongoing basis.
The reports are broken by day/week/month, and contain current sentiment, trend charts, key concepts associated with the topic, and references to source documents. There is an option to specify preferred Web sources that should be monitored and assessed in the reports. For example, real-time sentiment reports monitoring market-related sources can be generated.
