Show answer & explanation
Correct answer: D
Final answer: (A) is false, (B) is true.
Statement A (Strategic value of data mining is timestamping): False. The strategic value of data mining comes from extracting actionable insights, discovering patterns, building predictive models, and enabling better decisions or competitive advantage. Timestamping is a form of metadata (recording the time of events) and is not the core strategic purpose of data mining.
Strategic benefits: insight generation, prediction, optimization, and supporting business decisions.
Timestamping: useful metadata for ordering or temporal analysis, but not the strategic value itself.
Statement B (Information collection is an expensive process in building an expert system): True. Building an expert system requires eliciting knowledge from domain experts, encoding that knowledge into rules or models, testing, and validating — activities that are labor-intensive and costly.
Knowledge elicitation involves repeated interviews, refinement, and validation with experts.
Encoding and testing rules or heuristics, and maintaining the system, add to cost and effort.
Therefore, the correct conclusion is that the first statement is false and the second statement is true.
