DefinitionPattern discovery (パターン発見) is the processing that finds regularities and trends that recur in accumulated data.
ExplanationIt probes how items relate and how they shift over time, then feeds the results into product selection and promotions. The technique of digging such regularities out of large volumes of data is called data mining (データマイニング).
AnalogyLike a store manager skimming register records and noticing that prepared foods sell first on Friday evenings. You read a trend that no single record states.
Memory hook"Mining" means digging for ore: picture striking a rich vein in a mountain of data.
