Real-time web services such as Twitter allow users to express their opinions and interests, often expressed in the form of short text messages. Many business companies are looking into utilizing these data streams in order to improve their marketing campaigns, refine advertising and better meet their customer needs.

Thus, business could gauge the effectiveness of a recent marketing campaign by aggregating user opinions on Twitter regarding their product.
