DWR_CUST_SGMNT |
CUST_SGMNT_SEQ |
The prepaid churn prediction model identifies the characteristics of a prepaid customer likely to churn. When you apply the model you get a prediction of how likely a particular customer is to churn. This is based on customer information such as customer demographic information, service quality, recharge history, calling usage, interaction, and other factors. Using the patterns learned, the model can also perform the calculation over current customer base (called 'Apply') to predict which customers are mostly like to churn in next four months. With this knowledge, operators can initiate certain retention programs to reduce the customer churn rate. However, the churn prediction produces a likely to churn value. Further processing may be required to determine if it is desirable to retain a customer that is likely to churn. For example, you may only want to initiate retention programs for high value customers.
Prepaid Churn Prediction Model and Definition
There are several levels to define churn, namely Customer, Account, and subscription. For some operators with only limited business line, customer and account churn at same time, while subscription is at a lower level. Customer can stop using some products (termination of subscription) while continue to use the other products. In later case, operator still has the customer and may promote other products in the future. However, if customer completely stopped using any products from the operator, it is very difficult for operator to bring customer back.
In Oracle Communications Data Model, the churn was defined at Customer Level, which is, a customer is recognized as a churner only when he stop using any product from the operator.
If customers churn at a given month, we may receive the data only 3 months after the actual Churn. So time window should be adjusted.

Oracle Data Miner Workflow for PREPAID_CHURN_DT_AND_SVM
Workflow Description:
In data miner workflow, relevant columns are selected from DWD_CUST_DNA in Data Source node
Data is split into source and apply datasets
Source dataset is further split into training and test datasets
Training dataset is used to train prepaid churn models using two algorithms, Support Vector Machines and Decision Tree
Models are PRPD_CUST_CHRN_DT and PRPD_CUST_CHRN_SVM
Decision Tree Churn model, PRPD_CUST_CHRN_DT, details are extracted and stored in DWV_PRPD_CHRN_DT_NODE database view
Support Vector Machines Churn model, PRPD_CUST_CHRN_SVM, details are extracted and stored in DWV_PRPD_CHRN_SVM_FACTOR database view
Test dataset is stored in DWV_PRPD_CUST_CHRN_TST database view. This data is later used to extract ROC, LIFT, and Confusion Matrix from Support Vector Machines Churn model, PRPD_CUST_CHRN_SVM
Apply dataset is scored using trained prepaid churn models. PRPD_CUST_CHRN_DT model apply results are stored in DWV_PRPD_CHRN_DT_APPLY database view and PRPD_CUST_CHRN_SVM model apply results are stored in DWV_PRPD_CHRN_SVM_APPLY database view
Data Model Mining Target Tables
prepaid_churn_dt_and_svm workflow is executed when pkg_ocdm_mining_odmr_util.odmr_run_wf procedure invoked. Workflows status is extracted and stored into dwc_odmr_wf_exctn table by invoking pkg_ocdm_mining_odmr_util.odmr_wf_ltst_exctn_log procedure.
Invoke pkg_ocdm_mining_odmr_util.odmr_wf_stat_chk_upd_trgt_tab procedure to check the status of workflow execution. If workflow is executed successfully without any errors, then the procedure will invoke pkg_ocdm_mining_util.updt_mnng_trgt_prpd_chrn_dt and pkg_ocdm_mining_util.updt_mnng_trgt_prpd_chrn_svm procedures to update mining target tables for PRPD_CUST_CHRN_DT and PRPD_CUST_CHRN_SVM models.

The postpaid churn prediction model identifies the characteristics of a postpaid customer likely to churn. When you apply the model you get a prediction of how likely a particular customer is to churn. This is based on customer information such as customer demographic information, service quality, tariff plan, calling usage, interaction, and other factors. Using the patterns learned, the model can also perform the calculation over current customer base (called 'Apply') to predict which customers are mostly like to churn in next four months. With this knowledge, operators can initiate certain retention programs to reduce the customer churn rate. However, the churn prediction produces a likely to churn value. Further processing may be required to determine if it is desirable to retain a customer that is likely to churn. For example, you may only want to initiate retention programs for high value customers.
Postpaid Churn Prediction Model and Definition
There are several levels to define churn, namely Customer, Account, and subscription. For some operators with only limited business line, customer and account churn at same time, while subscription is at a lower level. Customer can stop using some products (termination of subscription) while continue to use the other products. In later case, operator still has the customer and may promote other products in the future. However, if customer completely stopped using any products from the operator, it is very difficult for operator to bring customer back.
In Oracle Communications Data Model, the churn was defined at Customer Level, which is, a customer is recognized as a churner only when he stop using any product from the operator.
If customers churn at a given month, we may receive the data only 3 months after the actual Churn. So time window should be adjusted.

The business problem is to group customers into generally homogeneous groups (Segments) based on customer demographic value, usage pattern and list of telecom products they subscribe to (customer subscriber history).Business Analysts can look into each segment to further understand the customer group discovered by the model and name each segment.
Customer Profiling
The discovered clustering rules draw a profile of the customers along with their product subscription. Thus, the clustering rules generated for each profile group show the most important similar characteristics in each group. For example, an operator may have a group having significantly shorter message (SMS) usage than any other group. Alternatively, there may be a group with extremely higher profit than any other group (covering high end customers).

Oracle Data Miner Workflow for Customer Segmentation KMEANS
Workflow Description:
In data miner workflow, relevant columns are selected from DWD_CUST_DNA in Data Source node
Data is split into source and training datasets
Training dataset is used to train postpaid customer profiling model using K-Means algorithm
Model is CUST_SGMNT_KMEANS
CUST_SGMNT_KMEANS model segment details are extracted and stored in DWV_SGMNT_DTLS database view
Segments centroid details are extracted and stored in DWV_SGMNT_CENTROID_DTLS database view
Apply dataset is scored using trained customer profiling model. Apply results are stored in DWV_CUST_SGMNT_APPLY database view
Data Model Mining Target Tables
customer_segmentation_kmeans workflow is executed when pkg_ocdm_mining_odmr_util.odmr_run_wf procedure invoked. Workflows status is extracted and stored into dwc_odmr_wf_exctn table by invoking pkg_ocdm_mining_odmr_util.odmr_wf_ltst_exctn_log procedure.
Invoke pkg_ocdm_mining_odmr_util.odmr_wf_stat_chk_upd_trgt_tab procedure to check the status of workflow execution. If workflow is executed successfully without any errors, then the procedure will invoke pkg_ocdm_mining_util.updt_mnng_trgt_cust_sgmnt procedure to update mining target tables for CUST_SGMNT_KMEAN model.
Following table gives the list of target tables (columns) that get updated/loaded/created:

Customer Lifetime Value
When a Service Provider wants know how valuable a customer is to the Service Provider for the next n years into future. Customer predicted Life Time Value can be combined with customer predicted churn behavior to make important business decisions such as whether to retain a customer. Customers predicted to have high LTV and also predicted to churn should be retained, whereas Customer predicted to have low LTV and also predicted to churn need not be retained. This is a regression model, where a continuous value is predicted and the source data is all those customers who have been on net for at least n years. n could be 3 or 5 years.Generalized Linear Model Regression

Oracle Data Miner Workflow - CUSTOMER_LTV_SRVL_VAL_GLMR
Workflow Description
In data miner workflow, relevant columns are selected from DWD_CUST_DNA in Data Source node
Data is split into source and apply datasets
Source dataset is further split into training and test datasets
Training dataset is used to train customer lifetime value and customer lifetime survival models using Generalized Linear Model Regression algorithm
Models are CUST_LTV_RGRSN_GLMR and CUST_SRVL_RGRSN_GLMR
CUST_LTV_RGRSN_GLMR model details are extracted and stored in DWV_LTV_RGRSN_MDL_DTLS database view
CUST_SRVL_RGRSN_GLMR model details are extracted and stored in DWV_SV_RGRSN_MDL_DTLS database view
Apply dataset is scored using trained customer lifetime value model. CUST_LTV_RGRSN_GLMR model apply results are stored in DWV_LTV_RGRSN_MDL_APPLY database view and CUST_SRVL_RGRSN_GLMR model apply results are stored in DWV_SV_RGRSN_MDL_APPLY.
Data Mining Target Tables
customer_ltv_srvl_val_glmr workflow is executed when pkg_ocdm_mining_odmr_util.odmr_run_wf procedure invoked. Workflows status is extracted and stored into dwc_odmr_wf_exctn table by invoking pkg_ocdm_mining_odmr_util.odmr_wf_ltst_exctn_log procedure.
Invoke pkg_ocdm_mining_odmr_util.odmr_wf_stat_chk_upd_trgt_tab procedure to check the status of workflow execution. If workflow is executed successfully without any errors, then the procedure will invoke pkg_ocdm_mining_util.updt_mnng_trgt_ltv and pkg_ocdm_mining_util.updt_mnng_trgt_srvl_val procedures to update mining target tables for CUST_LTV_RGRSN_GLMR and CUST_SRVL_RGRSN_GLMR models.
Following table gives the list of target tables (columns) that get updated/loaded/created:

The business problem is to measure customer sentiment regarding the service quality according to any text message received from the customer. Those text messages may be emails from customer, or written down by call center agents during call center calls, and so on.
Customer Sentiment
This model leverages Text mining capability provided by Oracle database. For more information, see Oracle Data Mining Concepts

Source Tables and Attributes
There are following two steps in preparing data for Customer Sentiment Analysis:
Prepare customers comment data: pkg_ocdm_mining_util PL/SQL package has prepare_cust_cmmnt_data to prepare the data. This procedure takes l_apply_day parameter as an input and inserts concatenated customer comments (three months prior to l_apply_day) into DM_CUST_CMMNT table.
Score customers’ comments using dictionary: pkg_ocdm_mining_util PL/SQL package has cust_sntmnt_manual_score to score customers’ comments using dictionary. This procedure takes p_training_pct (by default 50%) as an input and updates MANUAL_SCORE column of DM_CUST_CMMNT table for p_training_pct (by default 50%) of customers.
Customer comments data preparation (prepare_cust_cmmnt_data) and customers’ comments scoring (cust_sntmnt_manual_score) procedures are invoked by pkg_ocdm_mining_odmr_util.odmr_run_wf procedure.
DM_CUST_CMMNT is the main source table for Customer Sentiment classification model. The data in this table further transformed using Oracle Text to make it ready to be accepted by Oracle Data Mining.

Oracle Data Miner Workflow - CUSTOMER_SENTIMENT_SVM
Workflow Description
Manually scored customer comments data is selected as source dataset and customer comments data with no manual score selected as apply dataset
Source dataset is further split into training and test datasets
Training dataset is tokenized using Oracle Text algorithm
Tokenized Training dataset is used to train customer sentiment model using Support Vector Machines algorithm
Model is CUST_SNTMNT_SVM
Apply dataset is scored using trained customer sentiment model. CUST_SNTMNT_SVM model apply results are stored in DWV_CUST_SNTMNT_APPLY database view
Mining Target Tables
customer_sentiment_svm workflow is executed when pkg_ocdm_mining_odmr_util.odmr_run_wf procedure invoked. Workflows status is extracted and stored into dwc_odmr_wf_exctn table by invoking pkg_ocdm_mining_odmr_util.odmr_wf_ltst_exctn_log procedure.
Invoke pkg_ocdm_mining_odmr_util.odmr_wf_stat_chk_upd_trgt_tab procedure to check the status of workflow execution. If workflow is executed successfully without any errors, then the procedure will invoke pkg_ocdm_mining_util.updt_mnng_trgt_cust_sntmnt procedure to update mining target table for CUST_SNTMNT_SVM model.

The business problem is to identify the patterns of which products are typically purchased together or one after another over the lifetime of a customer. This helps in providing recommendations about which products should be presented to customers according to their potential acceptance score. A typical scenario is call center can call certain customers with some specific purpose to cross-sell some products. Operators need the list of customers to save promotion cost and improve efficiency.
Targeted Promotion
The trained model generates recommendations about promotion target products. This is done based on what products the customer has subscribed to taking into account other factors such as customers credit history and the risk involved in offering the particular product to the customer.

Oracle Data Miner Workflow - TARGET_PROMOTION_SVM
Workflow Description
VAS subscription data is selected from DWD_VAS_SBRP_QCK_SUMM table
VAS subscription data is split into Source for Training and Source for Apply datasets
Source for Training dataset is combined with DWD_CUST_DNA table to generate source dataset
Source for Apply dataset is combined with DWD_CUST_DNA table to generate apply dataset
Source dataset is further split into training and test datasets
Test dataset is stored in DWV_TARGET_PROMO_TST database view. This data is later used to extract ROC, LIFT, and Confusion Matrix from Support Vector Machines model, TARGET_PROMO_SVM
Training dataset is used to train target promotion model for selected product (in Target Promotion SVM node) using Support Vector Machines algorithm
Model is TARGET_PROMO_SVM
Apply dataset is scored using trained target promotion model. TARGET_PROMO_SVM model apply results are stored in DWV_TARGET_PROMO_SVM_APPLY database view
Update Mining Target Tables
target_promotion_svm workflow is executed when pkg_ocdm_mining_odmr_util.odmr_run_wf procedure invoked. Workflows status is extracted and stored into dwc_odmr_wf_exctn table by invoking pkg_ocdm_mining_odmr_util.odmr_wf_ltst_exctn_log procedure.
Invoke pkg_ocdm_mining_odmr_util.odmr_wf_stat_chk_upd_trgt_tab procedure to check the status of workflow execution. If workflow is executed successfully without any errors, then the procedure will invoke pkg_ocdm_mining_util.updt_mnng_trgt_prod_prmtn procedure to update mining target table for CUST_SNTMNT_SVM model.
Following table gives the list of target tables (columns) that get updated/loaded/created:
