Allied Irish Bank and their ‘Voice of Customer’ programme has accumulated a rich source of digitally available textual sources in the form of survey responses from their customers. This large collection of unstructured content contains relevant customer input, however, humans can only deal with a limited amount of unstructured content in a given time. To address this problem, the concept of sentiment analysis has been established to help human's process large amounts of unstructured content.
