One of the biggest challenges of Big Data is the disproportionate growth of unstructured data. According to a recent reports, 80 to 85 percent of business-relevant information originates in unstructured data. With the proliferation of smartphones and tablets, our society has become expert at generating it – from e-mails, text, tweets, blogs, news, call centers, reviews to images and video. As unstructured data continues to increase exponentially in both relevance and quantity, so does the challenge to discover valuable insight from the unstructured data. Text mining enables organizations to extract useful information and knowledge hidden in large quantities of unstructured data, thereby generating critical knowledge to drive better business decisions.
