Text Mining Handbook

Long on my stack, just making my way through: The Text Mining Handbook: Advanced Approaches in Analyzing Unstructured Data by Ronen Feldman and James Sanger. A very good overview of methods in unstructured data analysis. Largely non-technical, good introductions to methodologies, architectures and metrics required. Also like the chapter on the use of visualization techniques to augment text mining methods. Has an inside-the-book capability on the Amazon link.
