DefinitionBehavior log data (行動ログデータ) is data in which a system automatically records the actions and operations people perform on Web sites, apps, and so on.
ExplanationRecords build up of which pages were viewed and in what order, what was clicked, and what was bought. Actual behavior is kept as it happened without asking the person, so it helps reveal trends in how users act and is used to improve services and recommend products.
AnalogyLike footprints left in snow, the path someone took can be traced afterward even if they never thought about it.
Memory hookThe word log comes from a ship's logbook, so think of this as a logbook of behavior.
