1. Data & Text Mining Abhay Ahluwalia, Chris Bruck, Christopher Stanton, Stefanie Felitto, Mike Paulus BUAD 466: Introduction to Business Intelligence November 30, 2011

2. Data Mining Background  Definition – the process of analyzing data from different perspectives and summarizing it into useful information  Data Mining Software (ex. XL Miner) allows users to analyze data from many different dimensions, categorize it, and summarize the relationships identified

3. The Basics of Data Mining  Analyzes relationships and patterns in stored transaction data based on open-ended user queries  Classes : Stored data is used to locate data in predetermined groups  Clusters : Data items are grouped according to logical relationships or consumer preferences  Associations : Data can be mined to identify associations  Sequential patterns : Data is mined to anticipate behavior patterns and trends

4. Text Mining Background  Definition: the discovery by computer of previously unknown knowledge in text, by automatically extracting information from different written resources  Goal: to extract new, never-before encountered information  Text mining can expand the ability of data mining to deal with textual materials

5. Data are Key to Business Value DATA: Measures of variables in categories  Support Decision Making  Provide Basis for Forecasting  Important to  Obtain data from new sources (text mining)  Integrate (mash) information from multiple sources

6. Software Example #1: VAIM (Value- Added Information Mash)  MINING: finding patterns in data (pattern- oriented, record-oriented searches)  MASHING: Integrating information mined from multiple resources  Useful in Hospitals and for Government Campaigns

7. Software Example #2: IBM SPSS  Assists in Statistical Analysis in predicting trends  Categorizes data, Preforms Statistical Analysis  Multiple Regressions to suggest causality

8. Software Example #3: XL Miner  Add-In on Microsoft Excel Products  Builds off of software that companies already possess  Assists in predictive forecasting based on observed data trends  Demonstration Demonstration

9. Business Value Example #1: Grocery Store  Data mining using Oracle  Analyzed buying patterns  Finding lead to changes in Marketing  Increased revenues

10. Value Example #2 - University of Rochester Cancer Center  Using KnowledgeSEEKER software  Studied effect of anxiety of Chemotherapy on nausea  Analysis helped improved treatment of patients and improved quality of life.

11. Value Example #3: MGM Grand Hotel  Analyzed customer satisfaction and probability of return stay  Found that the front desk and room where most important  Focused next 6 months improving  10% improvement in attrition  Increased guest returns and profitability

12. Business Applications Pros:  Extracts new information and Combines human linguistic capabilities with the speed and accuracy of a computer Extracts new information and Combines human linguistic capabilities with the speed and accuracy of a computer  Can answer the ‘Why?’  Competitive advantage Cons:  Expensive  Requires Training  Dependent on structure of warehouses and repositories

13. Complications & Concerns  Invasion of Privacy  According to Lita van Wel and Lamber Royakkers in “Ethical issues in web data mining”, privacy is considered lost when information about an individual is obtained, used, or spread without that individual’s permission

14. More Complications Data is made anonymous before gathered into profiles, there are no personal profiles; therefore these applications de-individualize the users by judging them just by their mouse clicks De-individualization: tendency of judging and treating people on the basis of group characteristics instead of on their own individual characteristics

15. More Concerns  Companies can claim to collect the data for one purpose and use it for another  The growing movement of selling personal data as a service encourages website owners to trade personal data obtained from their site  The companies that buy the data make it anonymous and these companies and assume ownership of the data that they release http://www.youtube.com/watch?v=zdM6vzRHrG0

16. Even More Complications  Some web mining algorithms might use controversial characteristics to categorize individuals, such as sex, race, religion, or sexual orientation  This process could result in the refusal of service or a privilege to an individual based on his race, religion, or sexual orientation.

17. Application Recommendations & Conclusion  Sync data repositories (VAIM Software)  Training  Use Data Mining and Text Mining together
