Enterprise “imperatives” These imperatives translate into a process focus, into -– understanding and managing business processes – aligning business process with goals
and a focus on numbers and analytical magic -– measuring – modeling, forecasting, and predicting – optimizing
The statistical advantage Data Mining comprises a number of statistically rooted techniques for automated detection of patterns and relationships: Segmentation and clustering -- finding and applying the characteristics (dimensions) that best group data Link analysis -- detecting association patterns and rules Predictive modeling -- classification and scoring Predictive modeling -- regression for anomaly detection and forecasting
Text mining foundations Why isn’t Search enough? Search helps you find things you already know about. It doesn’t help you discover things you’re unaware of. Search results often lack relevance. Search finds documents, not knowledge.
Text mining foundations The old way -- an illustration: Mark Lombardi is an investigative reporter's Conceptual artist. His subject is conspiracy and scandal, his method is to “follow the money.” His pursuit results in big airy line drawings that exemplify Conceptual art's propensity for diagrams, masses of information and showing how the world works…. To keep facts and sources straight, he created a handwritten database that now includes around 12,000 3-by-5-inch cards. -- Roberta Smith in the New York Times, Dec. 25, 1998 Images on next slides are courtesy of Pierogi, pierogi2000.com
Text mining foundations Typical steps in text mining include -– Apply statistical &/ linguistic &/ structural techniques to identify, tag, and extract entities, concepts, relationships, and events within document sets. – Create a categorization/taxonomy from the extracts. – Apply statistical techniques to classify documents.

Text mining foundations These e-mail messages might be termed “semistructured.” What about a document marked up with XML? Does Structure = Syntax? What about Meaning (Semantics)?
Integrated analytics Is an exclusive focus on text and similar “unstructured” information sufficient? Remember those imperatives... – 360o views – Single version of the truth – Efficiency
Text mining applications Health Care Case Management Sources: clinical research databases, patient records, insurance filings, regulations Targets: enhance diagnosis and treatment, promote quality of service, increase utilization, control costs
Implementation roadmap On to processes: – How must you alter your information acquisition and management processes to access and exploit untapped sources? – What will your staff do differently? – What are operational support requirements?
