THE PROCEDURE FOR GROUPING PATENT DOCUMENTS BASED ON INTERNATIONAL CLASSIFICATION CODES AND TECHNOLOGY GROUPS

摘要

A method for the classification of patent documents by using international classification codes and product groups and manufacturers has for a novelty the specific way of calculating the coefficient of belonging and automatic withdrawal of the mapped products and manufacturers that are corresponding to the patent documents that have to be classified. The method comprises phase (100) including extraction of classification code from the patent documents and their automatic grouping to the groups of products and manufacturers. The method further comprises phase (101) in which the matrix is formed including: patent numbers, classification codes and groupes of products and manufacturers. The method includes also phase (103) in which coefficients of belonging of each classification codes within the groups (200) are calculated. The coefficient of (301) belonging depends of frequency of occurrence (203) of classification code (202) within the specified group (200), the total number of classification codess and the the total number of patent documents within one group. Phase (104) comprises forming of a matrix of classification of patent documents within mentioned groups, where is for each patent document in the list (201) of patent document determined coefficient (301) of belonging to each group (200), respectively. In phase (105) the algorithm determines the maximum (300) of coefficient of belonging. The proposed phases of method are executing in the classification unit (405) which communicates via communication network (402) with user unit (400) and the servers (403) which contain data related to products and manufacturers and also it communicates with servers (408) with available patent databases.
