Abstract
The association rule method describes the rules of the relationship between data items in the database, and explores the association relationship between variables through the confidence and support degree. Depending on the appearance of some items in a transaction, other items in the same transaction can be derived, that is, relationships hidden in the data or associations between each other. In this paper, an OBE teaching resource sharing system based on data mining technology is designed, and a mathematical model consisting of the definition of distance between rules, extraction of user preference features, similarity calculation and generation of recommendation results is constructed. According to the business process, the system function composed of teaching resource collection, teaching resource processing, teaching resource storage, teaching resource mining, teaching resource recommendation, teaching resource retrieval and teaching resource statistics is constructed. And the specific function is explained.
