METHOD OF PROVIDING SELECTED CONTENT ITEMS TO A USER

摘要

A method is disclosed for providing selected content items to a user; the selection of content items is based on metadata pre-assigned to content items, typically authored content metadata, and on metadata generated and associated afterwards, called derived content metadate; additionally, the selection of content items can be based also on context metadata, particularly derived context metadata. Derived metadata are automatically generating on the basis of derivation rules corresponding to algorithms to be applied to e.g. the content of content items, authored content metadata and context metadata. User profiles can be used for improving the selection quality; a method is also disclosed for building and maintaining user profiles based on machine learning techniques.
