Method for creating association index for the analysis of documents classified in a hierarchical structure using frequency distribution, a taxonomic structure, normalizing and weighting

摘要

The present invention is a computer-enabled method for combining information stored in a hierarchical classification structure, such as the International Patent Classification system, with the frequency of events resulting from human decision processes in order to generate an association index for a patent classification. The association index can then be used to quickly analyze a portfolio of patents.
