Marti Hearst, professor at the UC Berkeley School of Information, describes text mining as "the discovery by computer of new, previously unknown information, by automatically extracting information from different written resources. A key element is the linking together of the extracted information together to form new facts or new hypotheses to be explored further by more conventional means of experimentation... In text mining, the goal is to discover heretofore unknown information, something that no one yet knows and so could not have yet written down" (What Is Text Mining?).
