5 What is Business Intelligence? Business intelligence (BI) is a broad category of application programs and technologies for gathering, storing, analyzing, and providing access to data to help enterprise users make better business decisions. BI applications include the activities of decision support, query and reporting, online analytical processing (OLAP), statistical analysis, forecasting, and data mining. 5

47 Need for Real Time Analytics 47

48 The Amazon Example (the familiar example) Market Basket Analysis 48

49 What is Real-time Analytics? Real-time analytics is the use of, or the capacity to use, all available enterprise data and resources when they are needed. It consists of dynamic analysis, drawing inferences and reporting, based on data entered into a system up to the actual time of use. Real-time analytics is also known as real-time data analytics, real-time data integration, and realtime business intelligence. 49

51 Real-Time Applications based on Data Mining Why do we need Real time decisions? Recent industry changes like DO NOT CALL LIST, TIVO, spam blockers, aversion to junk post mail etc Importance of In-Bound Opportunity Finance-banking industry example 51

52 O V E R V I E W Data Mining 52

53 Data Mining Process of sifting through massive amounts of data to find hidden patterns and discover new insights Data Mining can provide valuable results: Identify factors more associated with a target attribute (Attribute Importance) Predict individual behavior (Classification) Find profiles of targeted people or items (Decision Trees) Segment a population (Clustering) Determine important relationships with the population (Associations) Find fraud or rare events (Anomaly Detection) 53

54 Data Mining Techniques(10g,10gR2) Unsupervised (clustering) K-means O-Cluster Non-Negative Matrix Factorization Anomaly Detection Supervised (classification and prediction) Adaptive Bayes Network (ABN) Naïve Bayes Support Vector Machine Decision Trees (PL/SQL code generator) 54

55 Oracle Data Mining Algorithms & Example Applications Attribute Importance Identify most influential attributes for a target attribute Factors associated with high costs, responding to an offer, etc. Classification and Prediction Predict customers most likely to: Respond to a campaign or offer Incur the highest costs Target your best customers Develop customer profiles Married >$50K Gender Income Status Gender HH Size A1 A2 A3 A4 A5 A6 A7 <=$50K Age M F >35 <=35 Single F M >4 Buy = 0 Buy = 1 Buy = 0 Buy = 1 Buy = 0 <=4 Buy = 1 55

62 Industry Specific Cases/Applications of Data Mining 62

63 The in-bound window of opportunity In-bound calls present a great opportunity for upsell and cross sell Data mining scoring for recommendations in Real time can provide CSR s with most likely loan product to offer Such an application was built using Oracle Data Mining for finance industry 63

64 Demo Scenario: Business Challenges About National Bank Fictional financial services provider Customer base: 5 million Large volume Call Center Business Challenges High customer turnover rate of 14% per year Associated replacement cost in millions per year Average cost of new customer acquisition: $250 Currently 2 products per customer, goal of achieving 4 per customer 64

65 Demo Scenario: Call Center Solution Predict in real-time customers propensity to attrite and to respond to various retention treatments Offer relevant and timely retention offers such as free online bill payment only to customers most likely to leave Predict in real-time customers propensity to respond to various cross- & up sell offers Target customers with relevant and timely cross sell offers at the time of call instead of Running costly, less relevant and less timely outbound retention and cross- & up-sell campaigns 65

66 Call Scenario A: Intelligent Cross- Sell Profile of caller (Linda Johnson): Female, 28 years old, single Holds checking and savings account at National Bank Medium-value customer Calls to change address (due to new job after grad school) Objectives of National Bank: Expand customer relationship through real-time intelligent cross- and up-sell offers 66

67 Call Scenario A: Upon caller identification, Linda Linda Johnson Johnson is is recognized recognized as as a a student student holding holding two two accounts accounts with with National. National. 67

68 In addition, upon caller identification, based based on on Linda s Linda s customer customer profile, profile, the the mining mining engine engine predicts predicts that that Linda Linda currently currently has has no no significant significant risk risk of of churning, churning, and and therefore therefore no no retention retention treatment treatment is is warranted, warranted, and and that that Auto Auto Insurance Insurance is is the the marketing marketing offer offer that that is is most most likely likely to to be be accepted accepted by by Linda. Linda. 68

69 Upon noting Linda s call reason, change of address, this this new new in-context in-context information information is is communicated communicated to to the the mining mining engine engine in in real-time. real-time. 69

70 Based on the new in-context information, the the mining mining engine engine predicts predicts in in real-time real-time that that Linda s Linda s churn churn risk risk has has not not increased increased but but that that the the most most appropriate appropriate offer offer now now is is Overdraft Overdraft Protection, Protection, addressing addressing Linda s Linda s likely likely increased increased financial financial needs. needs. 70

71 Linda s response to the extended offer is is noted noted by by the the agent agent using using the the offer offer response response buttons. buttons. The The response response information information is is communicated communicated to to the the mining mining engine engine in in real-time real-time for for self-learning. self-learning. 71
