IB Computer Science Topic A.4.7 Situations Benefiting from Data Mining Revision Notes (SL/HL) | RevisionDojo

Fraud Detection: Banking and Credit Card Companies

Problem: Identifying fraudulent transactions in real-time.
Solution:
1. Data mining algorithms analyze transaction patterns, such as unusual spending amounts, sudden location changes, or atypical purchase sequences, to detect anomalies.
2. These algorithms can flag suspicious transactions immediately, enabling the financial institution to block or review them before any financial loss occurs.

Example

If a credit card is suddenly used in multiple locations within a short time frame, the fraud detection system flags it as suspicious, prompting immediate review or temporary suspension to prevent potential financial loss.

Customer Segmentation: Retail and Marketing

Problem: Targeting the right customers for promotions.
Solution:
1. Data mining helps segment customers based on purchasing behavior, demographics, and past interactions.
2. By analyzing purchase history, product preferences, and buying frequency, businesses can identify high-value customers, loyal buyers, or at-risk customers and tailor personalized marketing campaigns that increase conversion rates and customer satisfaction.

Predictive Maintenance: Manufacturing

Problem: Reducing downtime and maintenance costs.
Solution:
1. Data mining analyzes equipment data, such as sensor readings, usage patterns, and historical failure records, to predict when maintenance is needed.
