Sentiment Analysis

Sample task view for our Clickworkers

You can quickly obtain information about customers from tweets, blog posts, comments and many other entries and consumer traces on the Web, for instance customer opinions about certain products, brands, services, campaigns or topics.
With our sentiment analysis service, you can quickly identify reactions to new products and react to them accordingly. This service also makes it easier to identify quality problems, as well as picking up on market moods and trends that are vital for the success of your marketing campaign and the planned introduction of a new product.

Because our sentiment analysis service is performed by human beings, we provide a high level of quality and can identify the sentiments/moods based on their contextual meaning rather than on individual words. Sarcasm and spelling errors are identified and correctly evaluated. The benefits of our sentiment analysis as compared to automated tools also make the service interesting for the R&D of artificial intelligence systems. The sentiment results can be used as training data for machine learning to increase the intelligence of the systems.

To make sure that you only obtain correct sentiment analysis results, we also ensure the quality by means of our reliable quality method, the “majority decision”.
