Apparatus and method for recommending to an individual selective information contained within a computer network

摘要

The method of the invention is executed by a computer under the control of a program stored in computer memory. The method includes the step of accumulating preference data for a set of individuals. The preference data is transformed from multi-dimensional data to lower-dimensional data using a principal component analysis. The lower-dimensional data is then converted into a recommendation map where predicted preference information for a selected individual is easily computed. Recommended content is then routed to the selected individual. The invention has been tested, by way of example, to recommend jokes to users based on their ratings of sample jokes.
