While many products appeal to consumers over a long time period, others have temporal relevance. Seasonal goods such as snow shovels and lawn care products may be highly desirable one month and useless two months later. Products for children exhibit similar patterns; the parent who buys toys for an infant should not receive infant toy recommendations for the same child two years later. Data mining research has addressed some issues in sequence identification and temporal associations. How can these results be used to influence recommendations to make them more helpful to consumers?
