Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary objective?To extract previously unknown, interesting patterns and knowledge from large datasets
2. What is the core KDD step?Represents the analysis phase of the Knowledge Discovery in Databases (KDD) process
3. Why do we need data mining?Because the amount of data is huge, and people can’t find useful clues by looking at it all by hand. Data mining automatically looks for patterns that can help predict the future or solve problems.
4. How does data mining find patterns?It uses special tools like clustering, which groups similar items together, and association rules, which find items that often appear together. It also checks for odd things that might be mistakes or special events.

Knowledge Discovery in Databases (KDD): The overall process of finding useful information and patterns in large datasets.
Clustering: An unsupervised learning technique that groups similar data points together without prior labels.
Association Rule Mining: A technique used to discover relationships between variables in large datasets, often seen in market basket analysis.
